1/38. popliteal artery entrapment syndrome: specific aspect.A case of popliteal artery entrapment syndrome (PAES) is reported. A non smoker, 63-year-old man, consulted for severe claudication of the lower limb, with a sudden onset. There was no past history of vascular disease. Neither the arteriography nor the arterial doppler led to definite diagnosis. In our case, only the C.T. scan was contributive to the diagnosis. The age, 63, at which this abnormality became symptomatic, the abrupt appearance of ischaemic symptoms and the embryologic type of the arterial stenosis were particular. The surgical management was the only therapeutic option.- - - - - - - - - - ranking = 1keywords = vascular disease (Clic here for more details about this article) |
2/38. Endovascular treatment of noncarotid extracranial cerebrovascular disease.The last two decades have witnessed a growing application of endovascular techniques for the treatment of atherosclerotic disease of the extracranial vertebral arteries, subclavian arteries, and brachiocephalic artery. Beginning with simple balloon angioplasty, these minimally invasive techniques have now progressed to the use of stent-supported angioplasty. Stent-supported angioplasty is currently providing a therapeutic alternative to traditional methods of open surgery for revascularization of these vessels and increasing the therapeutic options available for patients who have failed maximal medical therapy. Additionally, endovascular techniques are also being used successfully to treat a variety of nonatherosclerotic diseases affecting the noncarotid extacranial arteries, such as inflammatory, radiation, and anastomotic-graft strictures; acute intimal dissection; traumatic and spontaneous arteriovenous fistulas; and aneurysms or pseudoaneurysms. Continued innovation and refinement of endovascular devices and techniques will inevitably improve technical success rates, reduce procedure-related complications, and broaden the endovascular therapeutic spectrum for extracranial cerebrovascular disease.- - - - - - - - - - ranking = 5keywords = vascular disease (Clic here for more details about this article) |
3/38. Intracranial aneurysms in ehlers-danlos syndrome type IV in early childhood.ehlers-danlos syndrome type IV is of special interest to neurologists because of the risk of cerebrovascular complications. We describe a 5-year-old female with ehlers-danlos syndrome type IV, demonstrating multiple intracranial aneurysms and right middle cerebral artery stenosis. The diagnosis of ehlers-danlos syndrome type IV was confirmed by electron microscopic examination of a skin biopsy. To our knowledge, this is the youngest reported patient with intracranial aneurysms associated with the ehlers-danlos syndrome type IV. ehlers-danlos syndrome type IV should be considered in the differential diagnosis of cerebrovascular disorder and stroke in early childhood.- - - - - - - - - - ranking = 9.4889719155278keywords = vascular complication (Clic here for more details about this article) |
4/38. athletes with lower limb ischaemia.The case of a young healthy sportsman and acute exacerbation of chronic infragenicular pain is presented. Further investigation revealed an obstruction of the tibiofibular trunk due to an osteochondroma, arising from the fibula, which was immediately resected. osteochondroma is observed in 1-2% of the population and may present with vascular complications. In young patients and athletes, leg pain may be of vascular origin due to an entrapment or compression and should always be considered.- - - - - - - - - - ranking = 9.4889719155278keywords = vascular complication (Clic here for more details about this article) |
5/38. Endovascular interventions on persistent sciatic arteries.PURPOSE: To report our experience with interventional procedures used to treat complete and incomplete persistent sciatic arteries (PSA). case reports: Three female patients with PSAs displayed varying symptoms referable to this rare anatomical variant. In the first woman, a 1-year history of intermittent lower limb ischemia and an acute event prompted angiography, which demonstrated proximal occlusion of 2 crural vessels and a partially thrombosed sciatic artery aneurysm. To prevent further embolism, the aneurysm was excluded with a stent-graft. Endograft patency and aneurysm exclusion have been maintained up to 22 months. In a 41-year-old diabetic with chronic limb ischemia and digital gangrene, a flow-limiting stenosis of the sciatic artery was stented, restoring adequate pedal perfusion. The stent remained patent at the 18-month follow-up. The third patient suffered from a tumor-related pelvic hemorrhage originating from retrograde perfusion through the PSA, which had been ligated during previous surgery. Attempted embolization via a collateral connection between the incomplete PSA and the popliteal artery failed, and the patient died. CONCLUSIONS: Vasculopathies involving the sciatic artery are uncommon but may be amenable to interventional techniques, such as coil embolization and stent implantation. PSA aneurysm exclusion with a stent-graft may represent a new therapeutic alternative to standard surgery that obviates potential sciatic nerve damage, but the durability of the repair remains to be determined.- - - - - - - - - - ranking = 0.05194685403346keywords = diabetic (Clic here for more details about this article) |
6/38. A complication associated with the use of neonatal liver in orthotopic liver transplantation.BACKGROUND: Neonatal livers have been associated with a higher incidence of vascular complications but are nevertheless used because of donor shortage. AIMS: We report a complication of hepatic venous outflow obstruction because we retained the neonatal retrohepatic cava from the first transplant for retransplantation using a left lateral segment. methods: Technical and post-operative complications associated with a small "native" inferior cava and transplantation are described. RESULTS: Successful treatment with balloon angioplasty resulted in re-establishing the flow in the hepatic venous outflow tract. The child is well 3 years on with stable graft function. CONCLUSION: Percutaneous transluminal angioplasty is an effective non-surgical therapy for post liver transplant hepatic venous outflow obstruction. Replacement of the inferior venacava rather than retaining neonatal venacava may be a better option during retransplantation.- - - - - - - - - - ranking = 9.4889719155278keywords = vascular complication (Clic here for more details about this article) |
7/38. Risk of ischemic stroke in patients with symptomatic vertebrobasilar stenosis undergoing surgical procedures.BACKGROUND AND PURPOSE: There is little information to provide an estimate for stroke risk in patients with established stenosis or occlusion in the basilar or intracranial vertebral arteries undergoing surgical procedures. The objective of this study was to determine the ischemic stroke risk in this specific patient population. methods: A medical records linkage system retrospectively identified patients with a diagnosis of symptomatic vertebrobasilar stenosis or occlusion matched with surgical procedures. patients were selected if they had stenosis or occlusion of the basilar or intracranial vertebral arteries identified on vascular imaging before undergoing surgical procedures under general anesthesia. Clinical and radiographic features were reviewed, along with the nature of the surgeries and details of the perioperative management. Records were reviewed for the diagnosis of stroke occurring within 1 month of surgery. RESULTS: Thirty-eight patients with a history of symptomatic vertebrobasilar ischemia underwent 50 operations under general anesthesia, and 3 had ischemic strokes in the vertebrobasilar territory immediately after surgery, a per-procedure rate of 6.0% (95% confidence interval, 1.2 to 16.6) All 3 had episodes of prolonged hypotension (systolic blood pressure <100 mm Hg for >10 minutes) during surgery. CONCLUSIONS: The risk of perioperative stroke in patients with vertebrobasilar stenosis undergoing surgery under general anesthesia is 6.0%, which is notably higher than the risk for patients with other patterns of cerebrovascular disease.- - - - - - - - - - ranking = 1keywords = vascular disease (Clic here for more details about this article) |
8/38. Cardiac arrest due to ventricular fibrillation as a complication occurRing during rigid bronchoscopic laser therapy.Laser bronchoscopy is a usually well tolerated procedure for the treatment of obstructive lesions on the tracheobronchial tree, with a very low morbidity and mortality rate. Cardiovascular complications, including atrial and ventricular arrhythmias, and myocardial ischemia, have only rarely been reported during laser bronchoscopy. Cardiac arrhythmias during such a procedure are usually well tolerated but occasionally may be life threatening. Here we report a case of a young, female patient affected by Pulmonary tuberculosis with a cicatricial stenosis of the left main bronchus who developed an episode of prolonged cardiac arrest due to ventricular fibrillation (and no signs of acute myocardial ischemia) during rigid broncoscopic laser-therapy. Underlying coronary artery disease and other cardiac abnormalities were also excluded by subsequent cardiovascular examination. The clinical implications are also discussed.- - - - - - - - - - ranking = 9.4889719155278keywords = vascular complication (Clic here for more details about this article) |
9/38. Occult stenosis of the common carotid artery complicating mandibular reconstruction with a fibular free flap.An unsuspected severely stenosed common carotid artery that compromised a free flap for mandibular reconstruction is described. To our knowledge no one has advocated the assessment of the carotid tree before transfer of free tissue. We suggest that patients with several risk factors for peripheral vascular disease should have colour flow duplex imaging of the carotid system if transfer of free tissue is being considered.- - - - - - - - - - ranking = 1keywords = vascular disease (Clic here for more details about this article) |
10/38. Severe hypogammaglobulinemia associated with hepatic vein stenosis causes cytomegalovirus infection after living-related liver transplantation.Hepatic vein stenosis is a vascular complication that can lead to graft loss after liver transplantation. Although ascites frequently occurs as a symptom of hepatic vein stenosis, the development of severe hypogammaglobulinemia associated with hepatic vein stenosis has not been reported in the literature. An 8-year-old boy underwent living-related liver transplantation (LRLT) because of Wilson disease with chronic hepatic failure. Because de novo autoimmune hepatitis was diagnosed 1 year after LRLT, azathioprine, and prednisolone were added to the baseline immunosuppression of tacrolimus. The patient developed ascites with severe hypogammaglobulinemia (immunoglobulin g [IgG], 288 mg/dL) 2 years after LRLT. ultrasonography and angiography disclosed stenosis of the hepatic vein. The ascites completely resolved after percutaneous balloon angioplasty. Despite serum IgG trough levels of >500 mg/dL maintained by the addition of immunoglobulin, cytomegalovirus reactivation and sepsis occurred. serum IgG levels should be monitored to prevent opportunistic infections when hepatic vein stenosis is diagnosed after LRLT.- - - - - - - - - - ranking = 9.4889719155278keywords = vascular complication (Clic here for more details about this article) |
