2/122. 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 = 0.5250101782458keywords = aneurysm, pseudoaneurysm (Clic here for more details about this article) |
3/122. Unilateral middle cerebral artery stenosis in an adult with Down's syndrome--case report.A 29-year-old male with Down's syndrome presented with severe headache and vomiting. Computed tomography demonstrated subarachnoid hemorrhage. Left carotid angiography showed severe stenosis of the middle cerebral artery 2 cm distal to its origin, as well as abnormal hyper-vascularization near the stenosis site similar to that seen in moyamoya disease. Right carotid angiography showed no abnormalities. However, slight stenosis of the distal part of the bilateral vertebral arteries was noted. There was no aneurysm. We judged that the subarachnoid hemorrhage had been caused by rupture of the moyamoya-like vessel. Some patients with Down's syndrome have anatomical vascular abnormality and vascular fragility. The cerebral vascular abnormality found in this case may be part of the systemic vascular abnormalities associated with Down's syndrome. The vascular changes in some adult patients with Down's syndrome may be a sign of premature aging, and long-term studies with periodic vascular examination of patients with Down's syndrome need to be performed.- - - - - - - - - - ranking = 0.2keywords = aneurysm (Clic here for more details about this article) |
4/122. Isolated dissection of the celiac artery--a case report.Isolated arterial dissection, which occurs with the absence of aortic dissection, has been reported in carotid and renal arteries but rarely in visceral arteries. A case of isolated celiac artery dissection is reported here. A healthy 58-year-old man experienced sudden upper abdominal pain, which continued for several days. A body computed tomogram (CT) showed a multiple low-density wedge-shaped area in the spleen, which was diagnosed as splenic infarction, and an aneurysm with thrombus in the celiac artery. A selective angiogram showed dilatation of the celiac artery with wall irregularity, and proximal occlusion of the hepatic artery. The distal hepatic artery was fed by collateral arteries from the superior mesenteric artery. splenic infarction was probably due to the embolism from the thrombus in the dissected celiac artery. The absence of other vascular lesions and causes or risks for the arterial dissection would suggest the occurrence of spontaneous dissection. The dissection of visceral arteries should be considered in diagnosing acute abdominal pain.- - - - - - - - - - ranking = 0.2keywords = aneurysm (Clic here for more details about this article) |
5/122. Left cervical aortic arch with aortic coarctation and saccular aneurysm.Cervical aortic arch is a very rare malformation and is occasionally accompanied by other cardiovascular anomalies. A 48-year-old male patient had a left cervical aortic arch with aortic coarctation and saccular aneurysm distal to the coarcted segment. The major clinical manifestations were upper body hypertension with a 50-mmHg discrepancy between the upper and lower limbs and a loud continuous murmur in the upper chest and back. magnetic resonance angiography successfully depicted the anomalous aorta, and the aortic coarctation and aneurysm were surgically resected and the thoracic aorta was reconstructed. The discrepancy in blood pressure diminished after the operation, but antihypertensive medication was continued to satisfactorily control the hypertension.- - - - - - - - - - ranking = 1.2keywords = aneurysm (Clic here for more details about this article) |
6/122. Dysphagia and thoracoabdominal aneurysm.Two elderly patients who presented with gradually progressive dysphagia are described. Investigations excluded an intraluminal obstruction and showed extrinsic compression of the oesophagus by an aneurysmal aorta. Surgery was not performed and they were successfully managed with a liquid diet.- - - - - - - - - - ranking = 1keywords = aneurysm (Clic here for more details about this article) |
7/122. Contained rupture of an abdominal aortic aneurysm presenting as obstructive jaundice: report of a case.Chronic rupture of an abdominal aortic aneurysm (AAA) is a rare occurrence, the presentation of which is unusual, often mimicking other conditions such as femoral neuropathy or radicular compression syndrome. We report herein the case of an 87-year-old woman found to have a contained rupture of an AAA after presenting with back pain and obstructive jaundice. A computed tomography (CT) scan revealed the contained rupture of the aneurysm with a large hematoma compressing the common bile duct. Surgical repair of the aortic aneurysm was successfully performed and the patient remains well.- - - - - - - - - - ranking = 1.4keywords = aneurysm (Clic here for more details about this article) |
8/122. Superior vena cava obstruction: a review of the literature and report of 2 cases due to benign intrathoracic tumors.A review of the literature shows an increaseing number of cases of superior vena cava obstruction associated with malignancy and a marked decrease in the number of patients with caval obstruction of benign origin. In contrast to granulomatous diseases and aneurysms of the ascending thoracic aorta, which have decreased, the incidence of benign tumors is essentially unchanged. Clinical features of superior vena cava obstruction in relation to the anatomical site of obstruction and collateral pathways are correlated. Diagnostic approaches, including angiography and technetium scanning are usually definitive in outlining the site of obstruction. Experimental data and the numerous available techniques for surgical correction indicate that an entirely satisfactory procedure is not available for all patients. methods include the use of venous bypass or Teflon prostheses and the addition of a small arteriovenous fistula proximally. Two new cases of superior caval obstruction due to benign tumor are reported. In 1 patient, who had intrapericardial bronchogenic cyst with fibrotic caval obstruction and thrombosis, a method for caval reconstruction while maintaining venous return to the right atrium is described. The second patient had an intrathoracic thyroid adenoma and caval obstruction without thrombosis.- - - - - - - - - - ranking = 0.2keywords = aneurysm (Clic here for more details about this article) |
9/122. 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 = 1.2keywords = aneurysm (Clic here for more details about this article) |
10/122. 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 = 0.8keywords = aneurysm (Clic here for more details about this article) |
