Acquired causes of cardiac disease include ischaemic heart disease treatment 002 cheap 300mg retrovir, rheumatic heart disease treatment hemorrhoids cheapest generic retrovir uk, cardiomyopathies medications ibs discount retrovir, and aneurysms and dissection of the aorta or its branches treatment programs trusted 300mg retrovir. There is peripheral vasodilatation treatment effect definition buy retrovir without prescription, an increase in heart rate treatment quietus tinnitus order 100 mg retrovir amex, and a fall in systemic and pulmonary vascular resistance. Bosentan) are usually avoided as they are teratogenic in rats, although it is not known whether there are similar risks in humans. The functional class is determined by the level of activity that leads to dyspnoea (Table 10. In addition, women with previous cardiac events including transient ischaemic attacks, arrhythmia, pulmonary oedema or heart failure, and those with left-sided lesions. During pregnancy, women with heart disease require multidisciplinary team care,2 with regular antenatal visits and judicious monitoring to avoid or treat expediently any anaemia, infection or hypertension. There should be early involvement of obstetric anaesthetists and a carefully documented plan for delivery. All the literature supports a high risk of maternal death sufficient to make this condition one of the absolute contraindications to pregnancy. There is no evidence that monitoring the pulmonary artery pressure prepartum or intrapartum improves outcome. Progressive aortic root dilatation and an aortic root dimension >4 cm are associated with increased risk [D]. Pulmonary hypertension from any cause is dangerous and maternal mortality is 25 to 40 per cent [D],4,5 although this may be decreasing. Most pregnancy-associated deaths can be attributed to thromboembolism, hypovolaemia or pre-eclampsia. Management Acute aortic dissection should be suspected if a woman in late pregnancy presents with severe chest or interscapular pain, particularly if associated with systolic hypertension, different blood pressures in each arm or an early diastolic murmur, especially if she has predisposing risk factors. Vaginal delivery is appropriate for those with stable aortic root measurements <4. Warfarin is associated with warfarin embryopathy 13 and increased risks of miscarriage, stillbirth and fetal intracerebral haemorrhage. The literature supports a higher risk of aortic rupture and maternal death if the aortic root is >4 cm. Management the safest option for some mothers is to continue warfarin throughout pregnancy [C]. In the event of bleeding or the need for urgent delivery in a fully anticoagulated patient, warfarin may be reversed with prothrombinase complex and vitamin K, and heparin with protamine sulphate. If heparin is used, this should be in full anticoagulant doses, adjusted according to regular monitoring. Mitral stenosis is the most common rheumatic heart disease and is important in pregnancy because women may deteriorate secondary to tachycardia, arrhythmias or the increased cardiac output. The commonest complication is pulmonary oedema secondary to increased left atrial pressure and precipitated by increased heart rate or increased volume (such as occurs during the third stage of labour) [C]. Beta-blockers decrease heart rate and the risk of pulmonary oedema [D],11 but if medical therapy fails or for those with severe mitral stenosis, balloon mitral valvotomy may be safely and successfully used in pregnancy [D]. Most published evidence relating to mitral stenosis comes from retrospective cohorts and case series. The literature supports a higher risk of pulmonary oedema in severe mitral stenosis. Beta-blockers should be continued in pregnancy or initiated for symptomatic women [D]. The left ventricle may not be dilated but the ejection fraction is always reduced below 45% [C]. Percutaneous coronary intervention may provide a better alternative to thrombolysis in pregnancy as it is associated with less bleeding risk and also allows management of spontaneous dissections with coronary artery stents. However, stent implantation may be associated with an increased risk of coronary dissection in a vulnerable vessel [D]. For secondary prevention in women with known ischaemic heart disease, both aspirin and beta-blockers are safe in pregnancy [A]. The safest option for some women with mechanical heart valves is to continue warfarin in pregnancy, notwithstanding the associated fetal risks. Antibiotic prophylaxis against endocarditis is no longer recommended peripartum in women with heart disease. Has there been any progress made on pregnancy outcomes among women with pulmonary arterial hypertension Pregnancy outcomes and cardiac complications in women with mechanical, bioprosthetic and homograft valves. Low molecular weight heparin for the prophylaxis of thromboembolism in women with prosthetic mechanical heart valves during pregnancy. Acute myocardial infarction in pregnancy and the puerperium: a population-based study. It increases both the synthesis and release of thyroxine (T4) and triiodothyronine (T3) by the thyroid gland. Iodide is essential for the synthesis of thyroid hormones, and the thyroid gland actively traps iodine, which is then bound to a tyrosine molecule on a thyroglobulin molecule. Each molecule carries three or, more commonly, four molecules of iodine, making T3 or T4 respectively. Most circulating T3 is produced by peripheral deiodination of T4, by deiodinase enzyme, and is three times more potent than T4. Although the production of T3 is lower than that of T4, more T3 is available as a free, inactive compound. There is relative iodine deficiency in pregnancy as a result of loss through increased glomerular filtration and increased maternal production of T4 and T3. This results in increased uptake by the thyroid gland, which can result in enlargement and the appearance of a goitre. Fetal thyroid activity also depletes the maternal iodide pool from the second trimester, probably via diffusion along a concentration gradient. Deiodination also occurs in trophoblasts, preventing excess thyroid hormone exposure to the baby and perhaps explaining the fall in T4 found in the mother in later pregnancy. From this point onwards, the fetal thyroid axis is independent of the mother, and requires only transplacental iodine; there is little relationship between maternal and fetal thyroid hormone levels. The fetal cochlea, cerebral neocortex and basal ganglia are particularly sensitive to iodine deficiency. Iodination of water, salt or flour, or even annual injections for reproductive-age women, can easily achieve this. The introduction of iodine supplementation in certain areas of the developing world has also reduced both the miscarriage and the stillbirth rates. Therefore, some cough medicines and eye drops containing iodine should be avoided, as should radiological procedures utilising iodinated contrast dyes. Similarly, amiodarone, which is rich in iodine, should be avoided in pregnancy unless absolutely necessary for life-threatening arrhythmias. Radioactive iodine, which destroys the fetal thyroid, must never be used, even in early pregnancy, as damage can occur before there is active fetal tissue. The clinical signs of thyrotoxicosis are generally absent and, as the condition improves, T4 levels only remain elevated if true hyperthyroidism ensues. Antithyroid medication should not be used in hyperemesis as the thyroid abnormality is biochemical and self-limiting and is not related to an overactive thyroid [D]. When used, this type of medication is generally ineffective or required in unusually high doses. Pregnancy-specific reference ranges should be used: as T4 levels fall slightly during pregnancy, the lower limit of normal for free T4 is below that of non-pregnant women. As there is more conversion of T4 to T3, low levels of T4 are not necessarily indicative of hypothyroidism. Hyperthyroidism Hyperthyroidism occurs in approximately 1 in 500 pregnancies and is usually diagnosed and treated prior to the pregnancy, since untreated thyrotoxicosis is associated with reduced fertility. Less than 5 per cent of cases result from a toxic nodule, thyroiditis or a carcinoma. If pregnant women present with hyperthyroidism, hyperemesis or a molar pregnancy must be considered. Typical symptoms and signs of hyperthyroidism are difficult to separate from those of normal pregnancy, but poor weight gain in the presence of a good appetite or a tachycardia >100 beats per minute that is unresponsive to a Valsalva manoeuvre may indicate the disease. Unfortunately, many other symptoms, such as fatigue, warm peripheries, amenorrhoea, hair thinning and heat intolerance, are common in pregnancy and are not useful. It is essential to maintain euthyroidism in pregnancy, as uncontrolled disease is associated with maternal and fetal complications, including thyroid storm, heart failure and maternal hypertension. Observational studies have reported increased rates of premature labour, growth restriction and stillbirth. Treatment is similar to that for non-pregnant women, although radioactive iodine must not be given [D]. Surgery may be considered if medical treatment fails or there is a clinical suspicion of cancer or compressive symptoms due to a goitre. Both drugs are equally beneficial and the dose of either can be titrated against maternal wellbeing and biochemical status [D]. Antithyroid drugs can cause agranulocytosis and so a sore throat should prompt a full blood count. Even if the fetus does become hypothyroid, neurodevelopmental status is preserved, although careful control can still lead to neonatal hypothyroidism and even neonatal goitre. The goitres are generally small, clinically unimportant and tend to resolve within 2 weeks. No long-term fetal side effects of antithyroid drugs have been demonstrated, although the studies performed have been small and retrospective. Both drugs are expressed in breast milk, but have little effect on thyroid function. An ultrasound scan can be used to exclude a fetal goitre or clinically undetected fetal growth restriction. Fetal cardiac failure can result, leading to hydrops fetalis and death; fetal goitre can cause polyhydramnios or an obstructed delivery. The condition is also associated with craniosynostosis and intellectual impairment. The fetus can be effectively treated in one of two ways, either by maternal administration of antithyroid agents, which cross the placenta, or by delivery. The mother can be treated with T4 to offset any hypothyroid effects, as T4 will not cross the placenta [C]. The symptoms may therefore present in the baby only after a week and tend to be non-specific, such as poor weight gain, feeding and sleeping. Untreated fetal/neonatal hyperthyroidism is responsible for substantial mortality. If antibody levels are high, fetal/neonatal thyroid function should be checked, both in cord samples and in peripheral samples taken approximately a week after delivery. In pregnancies complicated by hypothyroidism, babies are normally grown and do not seem to have an increased risk of congenital anomalies. The insult is likely to occur in the first trimester, and therefore pre-conceptual optimisation of T4 therapy is important [D];9,10 ideally contraception should be used until euthyroidism is achieved. Referral to a physician or obstetrician interested in the field would seem prudent. As hypothyroidism is associated with subfertility, it is rare to make a new diagnosis in pregnancy. The classic symptoms of hypothyroidism, such as tiredness, constipation, anaemia, weight gain, carpal tunnel syndrome and hair changes, are common in pregnancy and cannot be relied upon to discriminate onset or worsening of the disease. As long as the patient is clinically euthyroid, thyroid function tests should be performed every few months, such as at booking and at 28 weeks. More frequent measurements are made if the clinical or biochemical condition is deranged [E]. The incidence varies widely and, when diagnosed biochemically, has been reported to be as low as 2 per cent in New York and as high as 17 per cent in Wales. Women on long-term T4 treatment following an onset soon after pregnancy should have this diagnosis considered. The condition is thought to be autoimmune and presents postpartum following a return to normal immunity after delivery. Ninety per cent of women will have thyroid antiperoxidase antibodies (compared with 10 per cent of the normal population). The disease may present initially between 1 and 3 months postpartum with thyrotoxicosis and later with hypothyroidism. If symptomatic with hyperthyoidism, beta blockers can be used; antithyroid drugs are inappropriate, as T4 production is not increased [D]. Hyperthyroidism is due to destruction of thyroid follicles and the release of preformed hormones. The destruction of thyroid follicles ultimately leads to the hypothyroid phase, which is more likely to be associated with symptoms such as tiredness and cold intolerance, and even a goitre. The period of hypothyroid state is variable, and permanent hypothyroidism can result (approximately 5 per cent of antibody-positive postpartum thyroiditis sufferers). The condition will recur in 70 per cent of future pregnancies and women with postpartum thyroiditis should be followed up to ensure that permanent hypothyroidism does not occur [E]. Pregnancy itself does not appear to influence the survival rates of women diagnosed with thyroid cancer.

The asterisks indicate the mitral valve orifice medications causing dry mouth buy retrovir in united states online, which is closed in systole (A) and open in diastole (B) symptoms dehydration cheapest generic retrovir uk. The arrowheads indicate hypoechoic material surrounding the heart symptoms zoloft dosage too high buy retrovir 300 mg online, consistent with a pericardial effusion medicine 44 159 buy online retrovir. The patient was transferred to the medical intensive care unit for further management symptoms for strep throat retrovir 300mg low cost. A bedside ultrasonographic examination of the thorax showed pericardial effusion and left pleural effusion schedule 8 medicines buy retrovir overnight. The patient improved and was discharged to the general medical unit to receive palliative care. The full triad, however, is quite uncommon in cases of tamponade, and the diagnosis requires a high degree of awareness. Atypical presentations of cardiac tamponade can be diagnosed earlier with the use of bedside cardiac ultrasonography, which is now commonplace in the intensive care unit. It can occur with a pericardial effusion of any size and progress to cardiac arrest unless it is diagnosed and treated promptly. Tamponade is generally thought of as being linked to hypotension; however, hypotension is present in only 26% of patients with cardiac tamponade (2). Some patients with tamponade may present with elevated blood pressure from underlying hypertension or high adrenergic tone (3), which was likely present in the patient described above. More reliable physical findings include pulsus paradoxus of 12 mm Hg or more (sensitivity 98%, specificity 83%) and tachycardia, tachypnea, and elevated jugular venous pressure (sensitivities 76%-82%) (2). Cardiac tamponade is often a clinical diagnosis when the appropriate clinical context and typical clinical features are present. However, subtle or atypical clinical and electrocardiographic findings are sometimes present, which may delay the clinical diagnosis of cardiac tamponade. Initially, increased intrapericardial pressure compresses the low-pressure atria, especially in diastole. A progressive increase in intrapericardial pressure leads to compression of the right ventricle, which leads to compromised cardiac output (1). The earliest echocardiographic sign of cardiac tamponade is atrial diastolic collapse; however, this finding alone is not very specific (1). Right atrial collapse, especially when it persists for more than one-third of the cardiac cycle, is highly sensitive and specific for cardiac tamponade (5). Left atrial collapse is seen in only 25% of patients with tamponade but is highly specific when present (5). Right ventricular diastolic collapse is more significant and more specific for 18 A Well-Known Cardiac Condition With a Unique Presentation 83 tamponade (1). The inferior vena cava is usually dilated with decreased inspiratory collapse due to impaired cardiac filling (5). She was treated with antithymocyte globulin, high-dose methylprednisolone, azathioprine, mycophenolate mofetil, and tacrolimus; however, her cardiac function did not recover appreciably. She was taken to the operating room for initiation of venoarterial extracorporeal membrane oxygenation as a bridge to mechanical cardiac support or transplant. As a consequence of the cardiogenic shock and intraoperative hypotension, anuric acute kidney injury (Acute Kidney Injury Network stage 3) developed, with the creatinine level peaking at 2. She received broad coverage with antimicrobials, including vancomycin, piperacillin-tazobactam, and caspofungin, in addition to Pneumocystis jiroveci prophylaxis with sulfamethoxazole-trimethoprim. After the citrate infusion was decreased to 250 mL hourly, laboratory test results were total calcium 10. Latest Blood Test Results Component Sodium, mmol/L Chloride, mmol/L Potassium, mmol/L Bicarbonate, mmol/L Serum urea nitrogen, mg/dL Creatinine, mg/dL Calcium (total), mg/dL Calcium (ionized), mg/dL Magnesium, mg/dL Inorganic phosphorous, mg/dL Albumin, g/dL Total bilirubin, mg/dL Direct bilirubin, mg/dL Alanine transaminase, u/L Prothrombin time, s Value 137 103 4. Infused into the afferent blood line, citrate chelates ionized calcium, thereby preventing the progression of the coagulation cascade. The majority of the calcium citrate complex is removed across the hemofilter, and the remainder is metabolized by the liver, kidney, and skeletal muscle. Each citrate molecule potentially produces 3 bicarbonate molecules through metabolism in the Krebs cycle (2). Calcium released from the calcium citrate complex, along with a continuous calcium infusion, restores serum ionized calcium concentrations. An increase in the total calcium level accompanied by a decrease in ionized calcium that results in a ratio of total calcium to ionized calcium of 2. The presence of a high anion gap metabolic acidosis usually indicates hypercitratemia with low serum bicarbonate in this clinical setting. The patient described above was receiving parenteral nutrition, caspofungin, piperacillintazobactam, and sulfamethoxazole-trimethoprim, and congestive or ischemic liver injury probably occurred secondary to cardiogenic shock, all of which are associated with liver injury that is hepatocellular or cholestatic or both. Impaired hepatic function in this patient likely resulted in citrate accumulation, which led to various biochemical abnormalities. When citrate toxicity is suspected, the rate of citrate infusion should be decreased, and laboratory tests must be rechecked 19 Electrolyte Abnormalities During Continuous Renal Replacement Therapy 87 regularly to ensure resolution of the toxicity. Further adjustments to the calcium infusion may be required depending on electrolyte results. Decreasing the citrate dose may increase the likelihood of recurrent hemofilter clotting. This may be managed by 1) decreasing the filtration fraction by increasing the blood flow rate or decreasing the ultrafiltration rate or 2) increasing the prefilter replacement fluid fraction to dilute the blood going through the filter and decrease the risk of filter clotting. Continuous venovenous hemodialysis with regional citrate anticoagulation in patients with liver failure: a prospective observational study. Total-to-ionized calcium ratio predicts mortality in continuous renal replacement therapy with citrate anticoagulation in critically ill patients. Continuous renal replacement therapy: cause and treatment of electrolyte complications. He had a past medical history significant for saddle pulmonary embolism (he was receiving warfarin for anticoagulation), congestive heart failure, type 2 diabetes mellitus, hypertension, degenerative joint disease, and monoclonal gammopathy of undetermined significance. The patient was initially treated with intravenous fluids for volume resuscitation and broad-spectrum antibiotics (ampicillin, vancomycin, and ceftriaxone) because of concerns of possible meningitis. Findings were unremarkable from blood and cerebrospinal fluid cultures and a chest radiograph. His antibiotic therapy was narrowed to only vancomycin, and he was transferred to the general medicine unit. Shortly after being transferred, the patient became hypotensive with altered mental status, fever, and tachycardia, prompting immediate fluid resuscitation and transfer back to the intensive care unit. Noncontrast magnetic resonance image shows a T1-hyperintense mass within the sella that is consistent with subacute pituitary hemorrhage. Laboratory test results included low serum cortisol, low free thyroxine, low thyrotropin, and hypernatremia. These findings, along with increased urine output, made a diagnosis of pituitary apoplexy more likely, and the patient was given high-dose hydrocortisone, desmopressin acetate, and fludrocortisone. Pituitary apoplexy is usually caused by hemorrhage, hemorrhagic infarction, or bland infarction of a pituitary adenoma. Peculiar vascularity of the pituitary gland and structural problems in small blood vessels in the suprasellar region may increase the risk of pituitary apoplexy. Pituitary apoplexy can be an elusive diagnosis because of its rarity and because pituitary adenoma can be undiagnosed at presentation (2). The first symptom of pituitary apoplexy is usually severe, postorbital, frontal, or occipital headache. Headache is the most consistently described and the most frequently occurring symptom in patients with pituitary apoplexy. Diplopia and other cranial nerve palsies can be caused by lateral compression of the cavernous sinus contents. Hypopituitarism is the primary cause of morbidity and death among patients with pituitary apoplexy. The corticotropin deficiency is most important because it may lead to Addisonian crisis. In studies of patients with pituitary apoplexy, up to 100% have corticotropin deficiency, up to 80% have thyrotropin deficiency, and up to 100% have gonadotropin deficiency (3). The most important aspect of treatment of pituitary apoplexy is administration of glucocorticoids, which results in hemodynamic stability. A supraphysiologic dose of glucocorticoids is required, not only to serve as replacement therapy but also to reduce the suprasellar edema. Hormone replacement therapy, including corticosteroids, may be required for several weeks. Most patients treated with hormone replacement and other supportive measures recover fully (3). Urgent surgical decompression is used only in patients with worsening neurologic symptoms, such as headache, and other signs of worsening suprasellar pressure, such as diplopia and visual field deficits. For these patients, early surgical intervention through a transsphenoidal approach has been associated with better outcomes. Pituitary apoplexy is a rare clinical diagnosis that commonly results from hemorrhagic infarction of a pituitary adenoma. Most cases of pituitary apoplexy are spontaneous, but many precipitants are known. Classically, symptoms include nausea and vomiting, severe headache, visual field deficits, diplopia, sometimes fever, and frequently hypotension. All patients require glucocorticoid replacement, and those with worsening neurologic symptoms may require surgical intervention. The day before admission he was seen in an urgent care facility, where he was noted to have a stable cardiopulmonary status, although he had a cough and coarse breath sounds on examination. He was prescribed azithromycin and an albuterol inhaler with a plan for reevaluation if the symptoms worsened. Bacterial cultures were started and a nasopharyngeal swab for influenza testing was obtained. The patient was given an empirical dose of oseltamivir and admitted to the general medical unit. Point-of-care ultrasonography showed no evidence of pneumothorax or deep vein thrombosis; a normal-sized, collapsible inferior vena cava with a decreased ejection fraction of 25% to 30%; and a small right ventricle. Formal venous ultrasonography and transthoracic echocardiography confirmed these findings. Chest radiography showed patchy opacities in the right mid and upper lung and in the left lung base that were more consistent with an infectious process than with pulmonary edema. For presumed septic shock and an elevated level of lactate, early goal-directed therapy was initiated with vasopressors and broad-spectrum antibiotics (vancomycin, levofloxacin, cefepime, metronidazole, and trimethoprim-sulfamethoxazole) in combination with the ongoing oseltamivir. During the 2011-2012 influenza season, the overall (adjusted) vaccine efficacy was only 47% in preventing influenza that required medical attention. As a result of this variance, influenza may still develop in patients who have received the vaccine (1). Influenza C virus causes a mild illness that does not require treatment and is therefore rarely discussed as being clinically relevant. The increase in critical care use during the 2009 pandemic heralded a renewed interest in management of severe influenza. Risk factors for severe disease include the following: age younger than 2 years or older than 65 years, American Indian or Alaskan native ethnicity, chronic cardiopulmonary disease, diabetes mellitus, immunosuppression, pregnancy or within 2 weeks post partum, and morbid obesity. Elderly patients who present initially with fever but no respiratory symptoms should also be tested. Diagnostic influenza testing should be performed as soon as possible, ideally within 5 days after symptom onset. Hospitalized patients should receive antiviral therapy for suspected or confirmed influenza, preferably with oseltamivir, zanamivir, or peramivir, even if more than 48 hours has passed since symptom onset. In the 2009 pandemic, oseltamivir-resistant strains of the H1N1 virus were documented; however, the prevalence remains low (3). In the 2009 pandemic, critically ill patients who had limited gastric absorption (eg, septic shock with poor limited gut perfusion or gastrointestinal hemorrhage) were eligible for compassionate use of intravenous zanamivir, although its availability was limited. At publication, intravenous 21 A Respiratory Infection 97 zanamivir was available only as an investigational drug through clinical trials; however, intravenous peramivir is available, but efficacy data on hospitalized patients are limited (4). Additional therapies for critically ill patients with influenza also garnered much attention after the 2009 pandemic. Corticosteroids should not be used because of the potential for prolonged viral replication and worse overall outcomes. Additional therapies, such as monoclonal antibodies, convalescent plasma (5), and hyperimmune intravenous immunoglobulin, are not routinely recommended currently. Even more than 48 hours after symptom onset, inpatients who have suspected or confirmed influenza should receive antiviral therapy, and respiratory droplet precautions should be instituted.

On abdominal ultrasonography, a small amount of free fluid was identified adjacent to the liver and gallbladder in addition to gallbladder wall distention and the presence of biliary sludge. Prophylactic antibiotic therapy included penicillin V, levofloxacin, metronidazole, acyclovir, and caspofungin. Chest radiography showed right upper lobe alveolar infiltrate that was confirmed with computed tomography of the chest, which also showed acute pulmonary embolism in segmental and subsegmental right upper 98 22 Infection in a Patient With Chronic Myeloid Leukemia 99 lobe pulmonary arteries, multiple bilateral pulmonary nodules, mediastinal adenopathy, and hypoattenuation within the spleen, which likely resulted from infarction. The patient became hypotensive with respiratory distress, fever, and altered mental status.

Sutures are placed through the fibromuscular tissue of the vagina but not through the underlying epithelium medicine in ukraine buy retrovir 300 mg otc. Delayed absorbable sutures should be used for the most distal stitches close to the bladder to avoid suture erosion or fistula formation into the bladder symptoms hiv cheap retrovir 300 mg mastercard. When the posterior arm is secured first medications ending in pril generic 300 mg retrovir fast delivery, it is easiest to place the apical posterior sutures first treatment brown recluse bite 100mg retrovir free shipping. Next top medicine retrovir 100mg on line, the posterior most distal sutures are placed medicine dropper buy retrovir with visa, which keeps the graft from bunching along the posterior vagina and minimizes the amount of sutures required for graft attachment. It is important to place the most apical stitch first while simulating desired suspension and maintaining the correct anatomic axis of the vagina in order to avoid the need for readjustment. The graft is trimmed to the appropriate length and then secured to anterior longitudinal ligament using two No. Great care is taken to avoid placement of the suture through the intervertebral disk or the periosteum of the vertebra rather than the anterior longitudinal ligament of the S1 vertebra as cases of osteomyelitis have been reported after robotic sacral colpopexy (Propst et al. Mobilization of the peritoneum during initial dissection facilitates reperitonealization after graft attachment. A cystoscopy is performed to confirm no injury to the bladder and patency of the ureters bilaterally. A vaginal examination should be performed at the completion of the procedure to ensure adequate suspension (without tension) of the vagina, and to determine if a posterior colporrhaphy and/or perineorrhaphy are necessary. As an aside, if a hysterectomy is planned prior to sacral colpopexy, a supracervical hysterectomy should be considered as preservation of the cervix and avoidance of amputation at the level of the vagina may decrease the risk of future mesh erosions (Osmundsen et al. If total vaginal hysterectomy is indicated, we recommend performing a vaginal hysterectomy with a double-layered closure of the vaginal cuff prior to the minimally invasive abdominal repair. In addition, care should be taken to avoid suturing the mesh to the vaginal apex suture line in order to minimize the risk of mesh erosion into the vagina. From a cost-efficiency perspective, conventional laparoscopy may be more appropriate following a vaginal hysterectomy; however, indications for robotic sacral colpopexy may still be present. Total laparoscopic or roboticassisted hysterectomy is another option; however, electrosurgical current spread to the vaginal apex tissues may predispose patients to mesh erosion. The objective success rate for abdominal sacral colpopexy, as defined by the lack of vaginal apex prolapse postoperatively, is reported to range from 78% to 100% (Nygaard et al. The most up-to-date Cochrane review on the surgical management of pelvic organ prolapse reported that abdominal sacral colpopexy had lower rates of recurrent vaginal apex prolapse [3. However, sacral colpopexy was significantly associated with a longer operative time, longer time to recovery and was more costly than transvaginal colpopexy. The estimated probabilities of treatment failure for symptomatic pelvic organ prolapse for open sacral colpopexy with concomitant urethropexy compared with no urethropexy were 0. Additionally, the calculated sacral colpopexy mesh erosion rate at 7 years was determined to be 10. All sacral colpopexy procedures in this trial were performed via the open approach; therefore, we can only extrapolate what the long-term outcomes after minimally invasive sacral colpopexy may be. Ventral rectopexy 211 Most of the literature has been focused on abdominal sacral colpopexy, but there are also data on outcomes after the laparoscopic and robotic-assisted approach as well. They found that the conversion rates and the operative time using this modality decreased significantly with increased surgeon experience. The authors concluded that outcomes after laparoscopic sacral colpopexy reflected those of open abdominal sacral colpopexy making the laparoscopic approach a good minimally invasive option for patients with vaginal apex prolapse. Additionally, open abdominal sacral colpopexy was associated with higher operative blood loss, longer hospital stay, and longer operative times. Randomized controlled trials have also reported on the outcomes after minimally invasive sacral colpopexy. The primary outcome in this study was operative time, and secondary outcomes looked at postoperative vaginal support, postoperative pain, functional activity, postoperative bowel and bladder symptoms, quality of life, and cost. At 6- and 12-month follow-up, anatomic and quality-of-life outcomes did not differ between the two groups. Cost was the primary outcome of this study, and the authors found that when costs of the robot and maintenance were considered, the robotic group had higher initial hospital costs ($19,616 vs. When costs of robot purchase and maintenance were excluded, there were no statistical differences in initial day of surgery costs for the robotic group compared to the laparoscopic group ($12,586 vs. The remaining studies that compare robotic and laparoscopic sacral colpopexy are small retrospective cohorts from either one or two institutions. Measured outcomes in these studies as well as the length of follow-up are variable, and findings differ among the studies, making it hard to draw generalized conclusions about the two different minimally invasive modes. A T-shaped mesh is used posteriorly, and is attached to the perineum and medial aspect of the pubococcygeus and iliococcygeus muscles in addition to the posterior vagina. If rectal prolapse is present, a colorectal surgeon can perform concomitant ventral rectopexy. While there are no data to support this, we feel that the robotic platform is especially useful for sacral colpoperineopexy as the visualization and the improvement in dexterity provided helps the surgeon to reduce the difficulty that is sometimes encountered with the perineal and levator muscle dissection as well as the suturing into the deep pelvis that is necessary to accomplish the operation. In this small retrospective study (N = 68), the authors compared the abdominal versus vaginal introduction of the mesh, which was then attached to the perineal body and rectovaginal septum either laparoscopically or transvaginally followed by laparoscopic attachment of a second mesh to the anterior vagina with laparoscopic securement of both mesh arms to the sacrum. At 6 months, there were no significant differences in objective anatomic outcomes. Data on the mesh erosion rate after sacral colpoperineopexy are sparse but have been estimated to be approximately 6% with sacral colpoperineopexy (Nosti et al. Patients with coexisting rectal prolapse should be referred to a colorectal surgeon for management at the time of pelvic organ prolapse repair. If minimally invasive abdominal sacral colpopexy is planned, concomitant ventral rectopexy may also be an appropriate choice for some patients (Cullen et al. The procedure is often performed with sacral colpoperineopexy and takes advantage of the extensive perineal dissection that is performed. Trocar placement remains the same for this procedure, and the colorectal surgeon usually performs his or her dissection either before or after the vaginal and presacral dissections. Care should be taken to avoid full-thickness bites into the lumen of the rectum as this will lower the risk of postoperative abscess and may reduce the rarer risk of osteomyelitis. A retrospective cohort study of 110 women who underwent laparoscopic sacrocolpopexy with rectopexy for management of pelvic organ and rectal prolapse found that constipation, fecal incontinence, and overall quality-of-life symptoms improved significantly postoperatively and was associated with low overall morbidity (Watadani et al. A few comparison studies between laparoscopic and robotic-assisted laparoscopic rectopexy exist. Other studies have also compared operative, clinical, and cost outcomes between laparoscopic and robotic ventral rectopexy and have reported no difference in perioperative complications; however, operative time and cost were significantly higher in robotic cases (de Hoog et al. A cohort study examining the long-term outcomes of robotic rectopexy for rectal prolapse followed 77 subjects for a mean follow-up time of 52. The authors of that study concluded that the long-term results of roboticassisted laparoscopic rectopexy were favorable (Perrenot et al. In this procedure, the vaginal apex is affixed to the proximal portion of the uterosacral ligament, which restores the apical support of the vagina. In order to suspend the vaginal apex to the uterosacral ligaments, the pubocervical and rectovaginal fascia must first be well delineated. Next, an Allis clamp can be used to elevate the vaginal cuff to enhance visualization of the uterosacral ligaments. Alternatively, a vaginal probe can be used to elevate the vagina, demarcating the uterosacral ligaments. A releasing peritoneal incision between the ligament and the ureter can be made in order to reduce peritoneal tension and subsequent ureteral kinking and injury from suture placement. This stitch is tied intracorporeally, and the opposite uterosacral ligament is reattached in the same fashion. If concomitant enterocele repair is performed, the uterosacral ligaments are tagged prior to dissection of the posterior vagina and rectovaginal septum. This allows the uterosacral ligaments to be easily identified for subsequent suspension. Separate mesh from the sacrocolpopexy can be used to perform the rectopexy, or the posterior arm of the sacral colpopexy mesh may be used to suspend the rectum as well. This study also determined that blood loss and length of hospital stay were significantly less in the laparoscopic group. However, uterine preservation surgery can also be done in women with uterovaginal prolapse who desire future fertility, who are concerned about early-onset menopause as a result of hysterectomy, or who feel that the uterus remains important for issues related to sexuality, body image, and cultural norms (Walters & Ridgeway 2013). While the rate of occult pathology remains low in asymptomatic women (Frick et al. For example, women with a history of cervical dysplasia, dysfunctional uterine bleeding, postmenopausal bleeding, and risk factors for endometrial carcinoma should not be offered uterine-sparing surgeries. Women who do choose to undergo uterine-preserving surgery should be thoroughly counseled about the need for routine cancer surveillance as well as the potential complications associated with future pregnancy (Burgess & Elliott 2012). Minimally invasive abdominal repair of uterovaginal prolapse with uterine preservation can be achieved with either laparoscopic uterosacral ligament suspension or laparoscopic sacral hysteropexy. Laparoscopic uterosacral ligament suspension can be done via conventional laparoscopy or with the assistance of the robot. The uterus is suspended to a portion of the ligament on each side, preferably using a permanent suture. The main advantage of this approach is that it restores normal anatomy and is associated with minimal risk of future pregnancy and delivery. There are very little data that report on outcomes after minimally invasive abdominal hysteropexy with uterosacral ligament suspension. Fifty subjects were included in this study, and the authors reported that the hysteropexy patients had better postoperative anatomic outcomes and experienced fewer failures as measured by reoperation rates when compared to the transvaginal group. Laparoscopic sacral hysteropexy has been described using varying techniques but is essentially performed using a technique similar to the one used for sacral colpopexy. A mesh or graft is sutured anteriorly and/or posteriorly, usually on the cervix, and sometimes a portion of the proximal vagina. The graft is then suspended to the anterior longitudinal ligament of the sacrum using permanent sutures. Anterior mesh placement should be avoided in patients desiring future fertility, and solitary posterior mesh placement is sufficient in these patients. Outcome data are also sparse for this procedure; however, studies looking at open abdominal sacral hysteropexy have shown similar high success rates when compared to open abdominal hysterectomy with concomitant sacral colpopexy (Costantini et al. These favorable outcomes support the use of minimally invasive sacral hysteropexy as a good option for women desiring uterine conservation at the time of uterovaginal prolapse repair. An advantage of robotic suspension compared to the transvaginal approach is that the risk of rectal and ureteral injuries at the time of placement of the suspension sutures may be reduced, as these structures are more easily delineated with robotic surgery (Rardin et al. There are no substantial data on the outcomes after uterosacral ligament suspension performed via a minimally invasive abdominal route; however, cure rates are reported to range from 76% to 90% (Behnia-Willison et al. Comparison studies have been done looking at laparoscopic uterosacral ligament colpopexy and transvaginal suspension. Over the last decade, the midurethral sling has become the most commonly performed procedure for the surgical management of stress urinary incontinence. However, prior to the evolution of the midurethral sling, the open Burch colposuspension was referred to as the gold standard for surgical management of stress urinary incontinence with a reported cure rate >80% (Carey et al. The procedure remains an important technique for management of stress urinary incontinence in patients who have failed treatment with the midurethral sling, who decline synthetic mesh placement, or who are undergoing concomitant laparoscopic or robotic prolapse repair surgery and would prefer to have an abdominal approach for their incontinence procedure. Many modifications of this procedure exist without any evidence of improvement in outcomes; therefore, the recommendation is to perform this procedure in the same fashion as the open abdominal technique using suture only. Many surgeons who have not adopted laparoscopic Burch due to a prolonged learning curve to achieve proficiency have found that robotic assistance is sometimes helpful for the challenging dissection and the suturing that are necessary to perform the procedure. We recommend the intraperitoneal approach because it allows for a larger dissection, creating a larger operating space that makes it easier and safer to suture. Additional advantages of the intraperitoneal approach is that it is safer in patients who have undergone prior retropubic surgery, and it allows for concomitant culdoplasty or paravaginal defect repair to be performed. For the purposes of this chapter, we will describe the intraperitoneal approach to the Burch colposuspension since the extraperitoneal approach is neither commonly performed nor taught. To perform the intraperitoneal technique, a three-way Foley catheter should be in place, and the bladder should be retrograde filled at the start of the procedure in order to help assist in visualizing the superior border of the bladder edge. The space of Retzius is first entered by creating a 2 cm transverse incision approximately 2 cm above the bladder reflection between the medial borders of the right and left obliterated umbilical ligaments. The proper plan is created when the loose areolar tissue is encountered and the pubic rami are visualized. Therefore, awareness of the proximity of the structures is necessary during the dissection of this portion. Once these landmarks are identified, the bladder is drained, and careful dissection is performed until the arcus tendinus fascia pelvis is identified. The surgeon places two fingers in the vagina and identifies the urethrovesical junction by placing gentle traction on the Foley catheter. With elevation of the vaginal fingers, blunt dissection is done along the vaginal wall lateral to the bladder neck. Care should be taken to avoid aggressive dissection within 2 cm of the bladder neck to avoid bleeding and damage to the periurethral nerve supply. The sutures are tied in an intracorporeal fashion with simultaneous vaginal elevation. A cystourethroscopy is performed after the sutures are passed to confirm ureteral patency and the absence of bladder and urethral injuries.
