1/8. Giant aneurysms of coronary arteries and saphenous vein grafts: angiographic findings and histopathological correlates.INTRODUCTION: Giant aneurysms that develop in native coronary arteries or saphenous vein grafts are morphologically defined as abnormally expanded outpouching vascular structures >4 cm in diameter. The location, morphology, and content of giant aneurysms account for adverse cardiovascular effects. methods: Two cases of giant aneurysms were studied comprehensively by noninvasive and invasive cardiac methods and subsequent histopathology. The first patient had a giant aneurysm that developed over a course of several years in a saphenous vein graft whereas the second patient had a giant aneurysm occurring within a native coronary artery. Accompanying clinical and angiographic findings are described. RESULTS: atherosclerosis and thrombosis were among the prominent histopathological findings. CONCLUSIONS: atherosclerosis and associated thrombosis within giant aneurysms result in obstruction of flow, distal embolization, and development of acute coronary syndromes including recurrent ischemic chest pain, unstable angina, and acute myocardial infarction. The options for clinical management of giant coronary or vein graft aneurysms include surgical excision, percutaneous coil occlusion and stent deployment, or medical approach.- - - - - - - - - - ranking = 1keywords = aneurysm (Clic here for more details about this article) |

3/8. A giant coronary artery aneurysm in the right coronary artery.Aneurysms of the coronary arteries are uncommon occurrences that usually develop secondary to atherosclerosis and are often asymptomatic. They are usually diagnosed incidentally during investigation for ischemic heart disease or at autopsy for sudden death. We present a case of a "giant" right coronary artery aneurysm (CAA) discovered incidentally at surgery. Pathological examination confirmed that this was a true aneurysm showing marked thinning of the media and fibrocalcific plaques with small, multifocal areas of lymphocytic infiltrates.- - - - - - - - - - ranking = 0.54545454545455keywords = aneurysm (Clic here for more details about this article) |
4/8. A true posterior tibial artery aneurysm--a case report.Aneurysms of infrapopliteal arteries are rare. The etiology is usually traumatic, and most aneurysms are false. The English-language literature reports only 33 cases of infrapopliteal arterial true aneurysms, of which 8 involve the posterior tibial artery. The etiology of these lesions is unclear; a fibromuscular fibrodysplasia similar to ulnar aneurysm may be hypothesized, but traumatic, atherosclerotic, inflammatory, and other pathological processes are also probably involved. The natural history seems to be related to thrombosis and distal embolism more than to rupture. Surgical indications are debated. Aneurysm repair with a complete restoration of the blood flow through the affected artery is particularly challenging owing to the small size of the vessels, and ligation may be required. We report, to the best of our knowledge, the first case of an atherosclerotic posterior tibial artery true aneurysm successfully treated with aneurysmectomy and end-to-end direct reconstruction with a documented good long-term patency. Clinical features, imaging findings, and surgical management are described; indications and treatments (open or endovascular) are discussed.- - - - - - - - - - ranking = 0.81818181818182keywords = aneurysm (Clic here for more details about this article) |
5/8. Aortopulmonary artery fistula in atherosclerotic pseudoaneurysm presenting with congestive heart failure after aortic valve replacement.An exceptional case of a giant pseudoaneurysm of the atherosclerotic ascending aorta complicated by aortopulmonary fistulization twelve years after aortic valve replacement is presented. The patient underwent successful surgical repair. In patients with a marked atherosclerotic thoracic aorta presenting with congestive heart failure and an acquired continuous systolo-diastolic murmur, aortopulmonary fistula should be considered and differentiated from ruptured sinus of valsalva aneurysm. Multi-slice computed tomography was the most useful diagnostic tool in planning surgical strategy and approach. Surgery is the treatment of choice for this serious albeit rare entity.- - - - - - - - - - ranking = 0.57041067628595keywords = aneurysm, pseudoaneurysm (Clic here for more details about this article) |
6/8. Uncommon presentation of Behcet's syndrome: aortic aneurysm and dissection due to Behcet's syndrome.Aneurysm and dissections localized to the ascending aorta are usually encountered in patients with atherosclerosis and hypertension. Behcet's syndrome is a rare vasculitic syndrome occasionally responsible for inflammation in small to large vessels. Aneurysm formation and dissection in the ascending aorta due to Behcet's disease is an even rarer presentation of this vasculitis that will be discussed in conjunction with a case presentation.- - - - - - - - - - ranking = 0.36363636363636keywords = aneurysm (Clic here for more details about this article) |
7/8. Is every chronic low back pain benign? Case report.BACKGROUND: There is a well-recognized association between chronic back pain and the existence of an AAA. In literature, there are few reported AAA cases that describe patients with extensive pressure erosion of the vertebral body. CASE DESCRIPTION: The authors present the case of a 38-year-old woman with chronic low back pain for the last 2 years in whom an AAA was formed during the follow-up period. The patient presented with an episode of low back pain following hard work 2 years ago. MR imaging of the lumbar spine was reported as disc degeneration at the L4-5 and L5-S1 levels. She was given medical treatment and was doing well with occasional back pain for a year. One year later, she suffered another disabling pain attack, and MR imaging revealed an additional focal disc protrusion at the L4-5 level. She was again medically treated. In August 2004, she presented with severe low back pain, and this time, MR imaging showed edema and erosion at the anterior part of L3 vertebra body. MR imaging studies (2- and 3-dimensional) depicted AAA as the cause. She was operated on, and the aneurysm was resected with graft repair of the site. She was pain-free in the postoperative period. CONCLUSIONS: The evaluation of a patient with chronic back pain needs a thorough clinical and radiological workup. Limited evaluation of the bony and nervous structures of the spinal canal radiologically is insufficient. Pre- and paravertebral structures as well as vertebral body should carefully be evaluated to diagnose other causes of pain.- - - - - - - - - - ranking = 0.090909090909091keywords = aneurysm (Clic here for more details about this article) |
8/8. atherosclerosis and central adiposity in a pediatric patient with AIDS treated with HAART: autopsy findings.Several types of cardiovascular lesions may develop in pediatric human immunodeficiency virus-positive (hiv )/acquired immunodeficiency syndrome (AIDS) patients, namely myocarditis, dilated cardiomyopathy, pericardial effusion, pericarditis, left ventricle hypertrophy, fibrocalcific arteriopathy, and aneurysms. Additional lesions may be discovered by histological examination. These include fibrocalcific lesions in medium-sized arteries and small vessels, mainly of the heart and brain, and vasculitis. In the large arteries the vasa vasorum may present chronic inflammatory infiltrates or leukocytoclastic vasculitis, resulting in aneurysms. We are reporting the case of a 14-year-old girl with mother-to-infant hiv transmission with a long history of several central nervous system infections and AIDS dementia, who received treatment with the HAART protocol (including a protease inhibitor) for 3 years. A year after beginning this treatment, cholesterol serum levels were 2.8 g/L and 3.8 g/L. autopsy findings showed gross and microscopic features of adult-type atherosclerosis involving the whole thoracic aorta, its main branches, and the coronary arteries. Remarkably, the abdominal aorta and all its branches were almost completely devoid of these lesions. At the same time, although the body presented extreme cachexia, there were obvious subepericardial, periadrenal, and peripancreatic fat deposits. The referred findings may have resulted from the well-known metabolic-dyslipemic syndrome induced by the HAART therapy and have not been specifically mentioned previously in the literature in the particular setting observed in the case of this patient.- - - - - - - - - - ranking = 0.18181818181818keywords = aneurysm (Clic here for more details about this article) |
