1/24. intracranial hypotension with parkinsonism, ataxia, and bulbar weakness.OBJECTIVE: To describe a case of spontaneous intracranial hypotension with a previously unreported constellation of presenting features. DESIGN: Case report. SETTING: Tertiary care center. MAIN OUTCOME AND RESULTS: We describe a patient with intracranial hypotension who presented with a parkinsonian syndrome and later development of ataxia and prominent bulbar symptomatology. headache was not a feature of her initial presentation and was only reported after repeated questioning during later evaluations. magnetic resonance imaging of the patient's head revealed findings characteristic of intracranial hypotension. An [18F]fluoro-m-tyrosine positron emission tomographic scan showed normal striatal activity, suggesting intact presynaptic nigrostriatal function. Opening pressure on lumbar puncture was reduced at 40 mm H2O. A source of cerebrospinal fluid leakage was not identified on nuclear cisternography and the patient underwent lumbar epidural blood patching, which resulted in complete resolution of her signs and symptoms as well as in a marked improvement in her imaging findings. CONCLUSIONS: The clinical spectrum of intracranial hypotension can be broadened to include parkinsonism, cerebellar ataxia, and prominent bulbar dysfunction. As with more common manifestations of the disorder, these features may resolve after appropriate treatment.- - - - - - - - - - ranking = 1keywords = leak (Clic here for more details about this article) |
2/24. Endoleaks following conventional open abdominal aortic aneurysm repair.OBJECTIVE: to describe the complication of <<<<endoleak>>>> following conventional open abdominal aortic aneurysm (AAA) repair. DESIGN: prospective case study. SETTING: two specialist vascular surgical centres. patients AND methods: six patients who had successful conventional open AAA repair. RESULTS: six patients presented with back or abdominal pain or hypotension between one and eighteen months later. An endoleak at the distal anastomosis was noted in five of the cases and one endoleak at the proximal anastomosis. All six cases were successfully repaired; two of these patients required Dacron graft replacement, whilst in four cases only direct resuturing was needed. There was no evidence of infection. CONCLUSIONS: an endoleak is not a phenomenon confined to stent grafts. It should be considered in all patients who present with back or abdominal pain within eighteen months of open AAA repair. The combination of computed tomography (CT) scan and digital subtraction angiography is most useful for preoperative diagnosis.- - - - - - - - - - ranking = 8keywords = leak (Clic here for more details about this article) |
3/24. amniotic fluid embolism.amniotic fluid embolism is a rare occurrence, with no single pathognomonic clinical or laboratory finding. diagnosis is based on clinical presentation and supportive laboratory values. We describe the case of a 17-year-old nulliparous woman at 27 weeks' gestation who had uterine bleeding, hematuria, hemoptysis, hypotension, dyspnea, and hypoxemia within 30 minutes of vaginal delivery. Laboratory values revealed diffuse intravascular coagulation. Chest films were consistent with adult respiratory distress syndrome. pulmonary artery catheterization revealed moderately increased pulmonary capillary wedge pressure. Supportive measures, including oxygenation, fluid resuscitation, and plasma, were administered. Central hemodynamic monitoring and inotropic support were necessary. Our patient recovered uneventfully and 6 weeks later was living an unrestricted life-style.- - - - - - - - - - ranking = 8.731697562133keywords = capillary (Clic here for more details about this article) |
4/24. Posterior ischemic optic neuropathy related to profound shock after penetrating thoracoabdominal trauma.Ischemic optic neuropathy is a rare cause of blindness reported most commonly in association with collagen-vascular diseases, infectious processes, and systemic hypotension related to massive exsanguinating hemorrhage. We report what we believe to be the first case of posterior ischemic optic neuropathy due to perioperative hypotension in a patient who had a penetrating thoracoabdominal injury with massive hemorrhage, severe hypotension, massive microcapillary circulatory leak, multiple system organ failure, and acute respiratory distress syndrome. Although the incidence of postoperative visual loss is low (-0.002%), awareness of this entity must be raised within the trauma surgical community.- - - - - - - - - - ranking = 9.731697562133keywords = capillary, leak (Clic here for more details about this article) |
5/24. Acute cardiomyopathy with recurrent pulmonary edema and hypotension following heroin overdosage.An 18-year-old man developed acute pulmonary edema following heroin overdose. Two days after initial improvement, there was recurrence of hypotension and pulmonary edema with severe hypoxemia refractory to mechanical ventilatory support utilizing positive and end-expiratory pressure. cardiac catheterization revealed elevated pulmonary capillary wedge pressure suggestive of left ventricular failure. The use of digitalis and diuretics resulted in prompt clinical improvement and ultimate recovery. Evidence is presented indicating that this patient represents an uncommon but important syndrome of acute cardiomyopathy with left ventricular failure which complicates the clinical course of certain cases of heroin overdose. Its physiologic diagnosis is of obvious importance in the choice of proper therapy, thereby increasing the patient's chances of recovery.- - - - - - - - - - ranking = 8.731697562133keywords = capillary (Clic here for more details about this article) |
6/24. Treatment of spontaneous intracranial hypotension with percutaneous placement of a fibrin sealant. Report of four cases.Spontaneous intracranial hypotension due to a cerebrospinal fluid (CSF) leak in the spine is an important cause of new, daily persistent headaches. Most patients respond well to conservative treatments including epidural blood patching. Limited options for effective treatment are available for patients in whom these treatments fail. The authors treated four patients (mean age 38 years; range 26-43 years) with percutaneous placement of a fibrin sealant. All these patients presented with intractable positional headaches. The CSF leak was located in the lower cervical spine in three patients and in the lower thoracic spine in one patient. Four to 20 milliliters of fibrin sealant was injected at the site of the CSF leak. Two of the four patients became asymptomatic within days of the procedure and thus avoided surgery. There were no complications of this procedure. Percutaneous placement of a fibrin sealant is a safe, minimally invasive treatment for spontaneous spinal CSF leaks and should be considered in patients in whom conservative treatment has failed.- - - - - - - - - - ranking = 4keywords = leak (Clic here for more details about this article) |
7/24. intracranial hypotension syndrome: a comprehensive review.intracranial hypotension may have variable clinical presentations, but has a rather uniform component of postural headache among its symptomatology. Its symptoms are explainable given the effects of the hypotension and attempts within the craniospinal axis to maintain volume homeostasis in the face of cerebrospinal fluid leakage (Monro-Kellie hypothesis). The imaging corollaries of the consequences of intracranial hypotension are especially well depicted on magnetic resonance imaging studies.- - - - - - - - - - ranking = 1keywords = leak (Clic here for more details about this article) |
8/24. diabetes mellitus and autonomic dysfunction after vacor rodenticide ingestion.A case of N-3 pyridylmethyl-N' 4 nitrophenyl urea (Vacor) rodenticide poisoning in a 52-year-old man is presented. Vacor is structurally related to alloxan and streptozotocin, agents that have been used extensively to produce diabetes mellitus in laboratory animals. Seven days after ingestion of Vacor, the patient presented in diabetic ketoacidosis complicated by postural hypotension and adynamic ileus. The patient recovered from ketoacidosis but has continued to require insulin. With infusion of arginine, glucagon rose from 185 to 650 pg./ml. and c-peptide from 0.5 to 3.4 ng./ml. Six weeks after onset of diabetes, no anti-islet-cell antibodies were detected. Muscle capillary basement membrane thickness on electron microscopy was found to be 1,918 /- 194 A. The absence of hyperglycemia after Vacor ingestion should not lead to complacency on the part of the attending physician. The patient must be observed closely for development of ketoacidosis and treated prophylactically with nicotinamide, the suggested antidote.- - - - - - - - - - ranking = 8.731697562133keywords = capillary (Clic here for more details about this article) |
9/24. Stent-graft treatment of patients with acute bleeding from hepatic artery branches.PURPOSE: To present a new treatment option in patients with acute bleeding from the hepatic artery branches. methods: Four male patients, 23-49 years old (mean 36.3 years), were treated for acute bleeding and subsequent transient hypotension. Bleeding episodes were secondary to hepatic artery pseudoaneurysms in two patients and surgical suture insufficiency in one patient. In the remaining patient, anastomotic leakage occurred following thrombolysis for hepatic artery thrombosis. patients were treated by endovascular placement of one or two balloon-expandable stent-grafts, ranging from 17 to 28 mm in length. RESULTS: All procedures were carried out without serious complications. All stent-grafts were deployed in the intended position with immediate cessation of bleeding and initial preservation of satisfactory blood flow. CONCLUSIONS: Bleeding from the hepatic artery can be treated by insertion of balloon-expandable stent-grafts in the acute setting.- - - - - - - - - - ranking = 1keywords = leak (Clic here for more details about this article) |
10/24. Control of systemic capillary leak syndrome with aminophylline and terbutaline.PURPOSE: patients with systemic capillary leak syndrome have a characteristic triad of hypotension, hemoconcentration, and monoclonal gammopathy. They have frequent and severe attacks of hemoconcentration and hypotension accompanied by marked plasma shifts. The exact role of this monoclonal protein is unknown, but it probably leads, in some way, to an increase in capillary permeability. Despite efforts to resuscitate the patients during an acute attack, the syndrome is often fatal. Some success has been obtained in preventing the attacks with the beta-adrenergic-stimulating agent terbutaline. The purpose of this study was to determine the effectiveness of aminophylline and terbutaline in the treatment of systemic capillary leak syndrome. methods: Over a decade, three patients with systemic capillary leak syndrome presented at our institution. All three patients were treated with terbutaline and aminophylline. prednisone was used during the course of treatment in each of the three patients. RESULTS: In contrast to previous reports of partial or temporary control of episodes, all three patients are alive with almost complete resolution of their recurrent attacks and have been able to return to their normal lifestyles. CONCLUSION: The regimen of terbutaline and aminophylline effectively prevents the attacks of hypotension and hemoconcentration that occur in systemic capillary leak syndrome. The role of prednisone is not clear. Until more is known about the pathophysiology of the disorder, treatment must remain empiric and supportive.- - - - - - - - - - ranking = 144462.69051837keywords = capillary leak syndrome, systemic capillary leak syndrome, systemic capillary leak, capillary leak, leak syndrome, systemic capillary, capillary, leak (Clic here for more details about this article) |
