1/850. A giant dissecting aneurysm mimicking serpentine aneurysm angiographically. Case report and review of the literature.Intracranial dissecting and giant serpentine aneurysms are rare vascular anomalies. Their precise cause has not yet been completely clarified, and the radiological appearance of such lesions can be different in each case according to the effect of hemodynamic stress on a pathologic vessel wall. For berry aneurysms, available evidence overwhelmingly favors their causation by hemodynamically induced degenerative vascular disease and there is an obvious need to determine the hemodynamic parameters most likely to induce the precursor atrophic lesions. In this study, a case of a giant dissecting aneurysm angiographically mimicking serpentine aneurysm of the right ophthalmic artery is reported and the relevant literature is reviewed to investigate the pathological characteristics and pathogenesis of this lesion. In the present case, radiological investigation of the lesion suggested a serpentine aneurysm, but the diagnosis was corrected to dissecting aneurysm subsequent to the pathological examination of the resected aneurysm. A giant dissecting aneurysm angiographically mimicking serpentine aneurysm and developing as the result of a circumferential dissection located between the internal elastic lamina and media is of particular interest when the etiology of these aneurysms is considered. To our knowledge this is the first report on intracranial dissecting aneurysm mimicking serpentine aneurysm angiographically. Our case illustrates the importance of careful serial section studies for a better understanding of the vascular pathology underlying the processes involved in intracranial serpentine aneurysms. We conclude that serpentine, dissecting and berry aneurysms may all arise by way of similar pathophysiological mechanisms.- - - - - - - - - - ranking = 1keywords = artery (Clic here for more details about this article) |
2/850. Atrial tamponade causing acute ischemic hepatic injury after cardiac surgery.A patient developed late cardiac tamponade after aortic valve replacement and coronary artery bypass grafting. nausea and dramatic elevations of serum aminotransferases were the initial clinical manifestations of cardiac tamponade. Severe acute ischemic hepatic injury secondary to isolated compression of both atrial cavities by two loculated thrombi was diagnosed.- - - - - - - - - - ranking = 1keywords = artery (Clic here for more details about this article) |
3/850. Subacute stent thrombosis occurring more than one month after implantation for acute myocardial infarction. Description of two cases successfully treated with angioplasty and further stenting.Two patients are described with anterior acute myocardial infarction who had a successful recanalization of a totally occluded left anterior descending coronary artery by means of primary angioplasty and stenting. Reinfarction occurred more than 1 month after implantation. At angiography, a totally occluded left anterior descending coronary artery at the site of stenting was observed and was effectively reopened with angioplasty and stenting in both cases. This report aims to emphasize that acute myocardial infarction still represents a major risk factor for subacute stent thrombosis and that this potentially catastrophic event may occur late after implantation. Potential implications for revascularization strategies and medical treatment are discussed.- - - - - - - - - - ranking = 2keywords = artery (Clic here for more details about this article) |
4/850. Anemic infarction of the liver resulting from hepatic and portal vein thrombosis.True anemic infarction of the liver is a rare lesion. Most of the reported cases are due to occlusion of the hepatic artery. Whether venous occlusion can result in such anemic infarcts has been disputed although few authentic cases have been reported. A case of polycytheia vera complicated by hepatic and portal vein thrombosis with anemic infarction of a large segment of the liver is presented. The case illustrates that anemic infarcts of the liver can result from venous occlusion. The intense congestion secondary to hepatic vein occlusion may cause secondary arterial hypoperfusion unless the portal vein is available as an outflow tract.- - - - - - - - - - ranking = 1keywords = artery (Clic here for more details about this article) |
5/850. diagnosis of MCA-occlusion and monitoring of systemic thrombolytic therapy with contrast enhanced transcranial duplex-sonography.A case of a successful systemic thrombolysis of an acute middle carotid artery occlusion is reported. The case underlines the role of contrast-enhanced transcranial color-coded duplex sonography as a noninvasive technique for rapid diagnosis of vessel occlusion in acute stroke. The diagnostic potential of transcranial color-coded duplex sonography for indication and monitoring of intravenous systemic thrombolytic therapy is demonstrated.- - - - - - - - - - ranking = 1.5867363520303keywords = artery, carotid, carotid artery (Clic here for more details about this article) |
6/850. Spontaneous native aortic valve thrombosis.Spontaneous thrombosis of a native aortic valve is an uncommon event that usually follows local trauma, such as cardiac surgery or left heart catheterization, or occurs as a complication of bacterial endocarditis. We report the case of a 65-year-old woman with a history of retinal artery occlusion and severe aortic valve stenosis, in whom transesophageal echocardiography revealed a mobile mass attached to the ventricular surface of the aortic valve. There was no evidence of any hypercoagulable state or infection process. Surgery was performed and a severely stenotic valve resected; a partially organized and firmly adherent free-floating thrombotic mass was observed on the ventricular surface of the aortic valve. Histologic examination demonstrated an organized thrombus. Eleven months after surgery the patient is doing well.- - - - - - - - - - ranking = 1keywords = artery (Clic here for more details about this article) |

Primary antiphospholipid syndrome: a cause of catastrophic shunt thrombosis in the newborn.This is a unique report of systemic-to-pulmonary artery shunt thromboses secondary to primary antiphospholipid syndrome and antithrombin iii deficiency in a neonate with cyanotic congenital heart disease. This infant with tricuspid atresia experienced thromboses of two modified Blalock-Taussig shunts en route to a bidirectional cavo-pulmonary shunt and potential future Fontan operation.

10/850. An aneurysm involving the axillary artery and its branch vessels in a major league baseball pitcher. A case report and review of the literature.baseball pitchers appear to be prone to aneurysms of the axillary artery and its branches. The cause is probably related to repetitive compression of or tension on the vessels at the level of the pectoralis minor muscle and the humeral head, which is exacerbated by the pitching motion. The incidence of aneurysms of the axillary artery and its branches among pitchers and other athletes is not known, nor is it clear whether pitchers who are at high risk of vascular injury can be identified before irreversible damage to the vessels has occurred. Perhaps patients who have documented compression or occlusion of the vessel with the arm in the abducted, externally rotated position are at higher risk. Screening pitchers to identify those with axillary artery compression, aneurysm, or thrombosis has also not been shown to be effective. Certainly, many pitchers will have some level of compression of the axillary artery with their arm in the pitching position but will never develop any clinical abnormality requiring treatment. Screening would therefore probably lead to a high false-positive rate. It is clear, however, that pitchers who complain of ischemia-type symptoms such as early fatigue or who have evidence of emboli require a complete evaluation to rule out any abnormality of the axillary artery or one of its branches. Orthopaedic surgeons who see pitchers and other athletes involved in repetitive overhead motions need to be aware of this disorder so that they order the appropriate tests and obtain a vascular consultation--and make a prompt diagnosis. Treatment will vary depending on the type of lesion and on which vessel or vessels are involved, and should be decided on by the team of surgeons treating the patient.- - - - - - - - - - ranking = 9keywords = artery (Clic here for more details about this article) |
