1/257. Atherosclerotic aneurysms of the superficial femoral artery: report of two ruptured cases and review of the literature.Isolated arteriosclerotic aneurysms of the superficial femoral artery are rare. In citing the literature a total of 30 cases in 28 patients in the last 25 years were found. In addition to the above cases, two aged patients with ruptured aneurysms of the superficial femoral artery are reported; these were managed successfully with partial aneurysmectomy and restoration of the circulation of the extremity with a synthetic graft. The prognosis for this type of aneurysm following surgical therapy is good, despite the advanced age of the patients, and amputation is relatively rare, occurring in only two out of the 30 aneurysms (6.6%) reported. The risk of rupture is 46.6% (14/30) and is greater than that found in peripheral aneurysms. This, in association with the possibility of the creation of thrombosis (5/30; 16.6%) or embolization (1/30; 3.3%), threatens the extremity itself as well as the life of the patient, increasing the risk of complications and even death at a rate of 66.6% (20/30). Timely diagnosis, immediate surgical reconstruction and prompt mobilization, however, can guarantee a good prognosis for these aged patients.- - - - - - - - - - ranking = 1keywords = aneurysm (Clic here for more details about this article) |
2/257. Aneurysm of the celiac trunk: diagnosis with US-color-Doppler. Presentation of a new case and review of the literature.Aneurysms of the celiac trunk are the rarest forms of aneurysms of the visceral arteries. Since 1958, when Schumaker reported the first case to be successfully treated surgically, only 69 cases have been reported in the international literature. The detection of such aneurysms, which are often asymptomatic, is mostly occasional. Approximately 15-20% of cases may be complicated by rupture with a mortality rate of around 80%. This eventuality makes surgical treatment mandatory even in asymptomatic cases. The authors report on their experience with the surgical treatment of one case of aneurysm of the celiac trunk and then go on to review the relevant literature.- - - - - - - - - - ranking = 0.3keywords = aneurysm (Clic here for more details about this article) |
3/257. coronary artery bypass grafting in a case with severe aortic atheromatosis associated with abdominal aortic aneurysm.A 69-year-old man with coronary artery disease associated with abdominal aortic aneurysm underwent a one-stage operation utilizing a low-flow cardiopulmonary bypass. Ordinary cardiopulmonary bypass was abandoned as a result of severe atheromatous finding in the entire aorta. However, coronary artery bypass grafting without cardiopulmonary bypass was hazardous as a result of heart enlargement and deteriorating function. Therefore, the abdominal aortic aneurysm was first replaced with a bifurcated graft. coronary artery bypass grafting with two arterial grafts was then performed successfully on the beating heart with the support of a low-flow cardiopulmonary bypass connected to the bifurcated graft.- - - - - - - - - - ranking = 0.6keywords = aneurysm (Clic here for more details about this article) |
4/257. Pseudoaneurysm of the internal carotid artery after shrapnel injury in World war II: demonstration by CT angiography with 3D MIP reconstruction.A case of pseudoaneurysm of the left internal carotid artery (ICA) after shrapnel injury is demonstrated by intra-arterial digital subtraction angiography (DSA) and computed tomography angiography (CTA) with subtraction technique. Although the pseudoaneurysm was well demonstrated by intra-arterial DSA, CTA was the only modality to demonstrate the three-dimensional shape of the perfused part of pseudoaneurysm and the aneurysmal neck, which affected the therapeutic strategy. The CTA technique is useful in the assessment of large pseudoaneurysms and for therapeutic planning.- - - - - - - - - - ranking = 0.91952024295181keywords = aneurysm, pseudoaneurysm (Clic here for more details about this article) |
5/257. Idiopathic nodular glomerulosclerosis.Idiopathic nodular glomerulosclerosis is an unusual entity with light microscopic and ultrastructural features similar to those of nodular diabetic glomerulosclerosis but without evidence of abnormal glucose metabolism. We report 2 patients whose renal biopsies showed nodular glomerulosclerosis with afferent and efferent arteriolosclerosis, glomerular basement membrane thickening, focal mesangiolysis and capillary microaneurysm formation, and who had no evidence of abnormal glucose metabolism or other features of diabetes mellitus. review of the literature shows that, of the 27 reported cases of idiopathic nodular glomerulosclerosis (not including the 2 cases reported herein), 11 showed evidence of abnormal glucose metabolism or were frankly diabetic. Of the remaining 16 cases with normal serum blood glucose measurements, 3 had diabetic retinopathy and 1 had a delayed insulin response curve. The cause and pathogenesis of the glomerular nodules are discussed, and it is suggested that arteriolar stenosis and glomerular ischemia may be involved in the development these lesions.- - - - - - - - - - ranking = 0.1keywords = aneurysm (Clic here for more details about this article) |
6/257. Ischaemic complication following obliteration of unruptured cerebral aneurysms with atherosclerotic or calcified neck.We report three cases of ischaemic complications following direct surgery of unruptured cerebral aneurysms having necks with atherosclerotic or calcified walls. Among 30 patients we treated directly for unruptured aneurysm over the last 4 years, 6 had 8 such aneurysms. Atherosclerotic or calcified neck was a major contributor to postoperative ischaemic sequelae in our recent series of unruptured aneurysms treated surgically, and common technical problems during surgery seemed to have caused ischaemic complications in the 3 patients reported here. In this report, attention is given to ischaemic complications in the treatment of such aneurysms.- - - - - - - - - - ranking = 0.9keywords = aneurysm (Clic here for more details about this article) |
7/257. A bidirectional closing aortic dissection from an atherosclerotic distal aortic arch aneurysm: report of a case.We experienced one rare case of a 76-year-old male with a Stanford type A bidirectional closing aortic dissection from a coexisting atherosclerotic distal arch aneurysm. He showed a cardiac tamponade, and effective pericardial drainage allowed us to conservatively manage the patient. Both an increase in the size of the aneurysm and a recrudescent dissection in the descending aorta were identified 2 months after the onset. A scheduled surgical repair was successful. The coexistence of an acute aortic dissection and an atherosclerotic aneurysm increases the risk of an aortic rupture, particularly at the confluence of the two lesions. Meanwhile, the management of a closing aortic dissection remains controversial because its characteristics still are not well known. We studied not only the pathogenesis but also the management of these two forms of aortic disease and their complex relationships.- - - - - - - - - - ranking = 0.7keywords = aneurysm (Clic here for more details about this article) |
8/257. Epstein-Barr virus-containing T-cell lymphoma and atherosclerotic abdominal aortic aneurysm in a young adult.Malignant lymphoma infiltrating the abdominal aorta and resulting in an aortic aneurysm has never been documented. We report here a case of angiocentric T-cell lymphoma in a 33-year-old man who for months presented intermittent fever, splenomegaly, and an abdominal pulsatile mass. angiography revealed extensive aneurysmal dilatation of the infrarenal abdominal aorta, bilateral iliac artery, and right common femoral artery. Splenic abscess and infected abdominal aortic aneurysm were initially suspected. An urgent splenectomy and aneurysmectomy with an aortic bifemoral bypass were performed. Pathological examination of the aortic aneurysm showed extensive necrosis, severe atherosclerosis, and lymphoma cell infiltration of the aortic wall. The lymphoid cells in the aorta and spleen were stained positive for CD45RO, CD56, and CD8, but negative for CD4 and CD19. Double-labeling immunohistochemistry and in situ hybridization using EBER1 for Epstein-Barr virus (EBV) revealed positive nuclear staining in the atypical T-lymphoid cells. This is the first definitive proof of peripheral T-cell lymphoma involving the abdominal aorta. Our evidence also supports that the EBV infection of T cells could be responsible for the atherosclerosis and hypertriglyceridemia, and the angiocentricity of the tumor cells apparently results in the presenting atherosclerotic aortic wall destruction, providing an additional causative concept for abdominal aortic aneurysm.- - - - - - - - - - ranking = 1keywords = aneurysm (Clic here for more details about this article) |
9/257. Isolated true atherosclerotic aneurysm of the profunda femoris artery. Case report.The authors report a case of true isolated atherosclerotic aneurysm of the profunda femoris artery. On the basis of a careful search of the literature some aspects of this rare disease are illuminated in terms of its low incidence, pathologic background and treatment; the last should always be aggressive due to the high possibility (about 50%) of major complications mainly represented by rupture. Simple aneurysmectomy without flow re-establishment may be allowed only if the femoropopliteal tract is normal- - - - - - - - - - ranking = 0.6keywords = aneurysm (Clic here for more details about this article) |
10/257. Giant unruptured aneurysm of the thoracic aorta--a case report.An asymptomatic 88-year-old woman underwent a screening medical examination. The chest x-ray film showed a large mediastinal mass with calcification. Both chest computed tomography and nuclear magnetic resonance imaging revealed an unruptured aortic aneurysm, predominantly affecting the ascending aorta and the proximal part of the aortic arch. Its maximum diameter was 10.5 cm. An ascending aortic aneurysm more than 10 cm in diameter is very rare. She died of acute pulmonary embolism unrelated to the aneurysm, and autopsy indicated that the etiology of the aneurysm was atherosclerotic degeneration. Retrospectively, the natural progression of the aneurysm was able to be followed on a series of chest x-ray films obtained over 18 years.- - - - - - - - - - ranking = 0.9keywords = aneurysm (Clic here for more details about this article) |
