1/25. 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) |
2/25. 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) |
3/25. 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) |
4/25. 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) |
5/25. Volume subtraction three-dimensional CT angiography for cerebrovascular disease: report of two cases.We report two cases in which volume subtraction three-dimensional CT angiography (VS-3DCTA) was used for cerebral aneurysm and vascular stenosis with intramural calcification. Case 1: VS-3DCTA with volume rendering clearly showed carotid cave aneurysm of the internal carotid artery. The location and size of the aneurysm was confirmed by digital subtraction angiography (DSA). In evaluation of the aneurysm, VS-3DCTA was equal to DSA and endovascular findings. Case 2: VS-3DCTA with volume rendering clearly showed stenosis of the middle cerebral artery, and intramural calcification with the cause of the stenosis was subtracted. On the other hand, it was difficult for DSA to reveal the stenosis because of the limitation of the imaging angle. In evaluation of the stenosis, VS-3DCTA was superior to DSA. VS-3DCTA was an important diagnostic tool that enabled visualization of the aneurysm in the area of the skull base and stenosis of the intracerebral artery.- - - - - - - - - - ranking = 4keywords = vascular disease (Clic here for more details about this article) |
6/25. popliteal artery entrapment syndrome.popliteal artery entrapment syndrome is a rare but potentially limb threatening peripheral vascular disease occurring predominantly in young adults. We report a case of a 17-year-old boy who presented with intermittent claudication on the right side. Digital subtraction angiography revealed bilateral, focal narrowing of the popliteal arteries. magnetic resonance imaging displayed compression of the arteries by the medial head of the gastrocnemius muscles. The mechanism, presentation, imaging findings, and management of this rare disease are discussed.- - - - - - - - - - ranking = 1keywords = vascular disease (Clic here for more details about this article) |
7/25. Cystic adventitial disease: a case report and literature review.Cystic adventitial disease (CAD) is a rare non-atherosclerotic cause of peripheral vascular disease (PVD). We describe a 54-year-old man who presented with calf claudication and catheter angiography showed the typical scallop appearances of CAD. Surgery involved resection of the diseased segment with a femoral popliteal venous bypass graft. A literature review revealed the different theories for pathogenesis, the investigation of choice being catheter angiography and the treatment excision with bypass grafting.- - - - - - - - - - ranking = 1keywords = vascular disease (Clic here for more details about this article) |
8/25. Iatrogenic entrapment: femoro-popliteal vein bypass graft.A rare cause of occlusive vascular disease is the "popliteal artery Entrapment syndrome." The most common cause of this problem is abnormal position of the popliteal artery caused by abnormal migration of the medial head of the gastrocnemius. An acquired form can occur because of tunneling defects by inadvertent placement of venous bypass graft medial to the medial head of the gastrocnemius muscle. We present 2 cases of iatrogenic entrapment of the femoropopliteal bypass graft. Investigations revealed compression of the graft with extension of the knee. Both cases were treated surgically. Intraoperatively there was evidence of compression of the graft between the tendons of the semitendinosus and the gracilis muscles and the medial head of the gastrocnemius muscle. Treatment involved division of the medial head of the gastrocnemius in 1 patient, and in the other, the tendons of gracilis and semitendinosus were divided. No compression of the graft was noted postoperatively by noninvasive test. No significant mobility issues caused by the division of muscle or the tendons were present in the postoperative period.- - - - - - - - - - ranking = 1keywords = vascular disease (Clic here for more details about this article) |
9/25. Diffuse dermal angiomatosis.Diffuse dermal angiomatosis (DDA) is an acquired, benign vascular proliferation characterized clinically by poorly circumscribed, violaceous, livedoid plaques with frequent ulceration. Histologically, a diffuse interstitial proliferation of CD31-positive endothelial cells is present within the papillary and reticular dermis. Endothelial atypia, atypical mitoses, and vasculitis are lacking. We describe a case of DDA in a 53-year-old man with peripheral vascular atherosclerosis that resolved following revascularization. Early correction of the associated ischemic peripheral vascular disease promotes resolution of this unusual clinicopathologic entity.- - - - - - - - - - ranking = 1keywords = vascular disease (Clic here for more details about this article) |
10/25. Iliac arteries injury secondary to extracorporeal shock wave lithotripsy: a case report.The authors report a case of a 40-year-old woman who developed claudication of the right limb 3 months after extracorporeal shock wave lithotripsy (ESWL) owing to a pyelic calculus. Patient had no previous vascular disease. Arteriography revealed a 12-cm-long 80% stenosis of the right common, external, and internal iliac arteries; the rest of the arterial tree had no detectable pathology. Arterial complications related to ESWL have been reported before in patients with aortic aneurysms or very intense calcifications. To the authors' knowledge this is the first report of ESWL-induced injury in a patient without previous arterial pathology.- - - - - - - - - - ranking = 1keywords = vascular disease (Clic here for more details about this article) |
