1/217. Primary venous aneurysms--case reports.Venous aneurysms are rare lesions that may be the source of pulmonary emboli and can result in death. The authors have recently treated several patients who had venous aneurysms of the upper extremity, lower extremity, and jugular system. Venous aneurysms usually appear to have a safe natural history in these locations, although all of the reported patients required surgery after the development of symptoms owing to complaints of pain, and/or cosmetic appearance, and/or a diagnosis of thrombosis. These cases are presented, along with a review of venous aneurysms occurring at other sites and their causes.- - - - - - - - - - ranking = 1keywords = thrombosis (Clic here for more details about this article) |
2/217. 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 = thrombosis (Clic here for more details about this article) |
3/217. 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 = 1keywords = thrombosis (Clic here for more details about this article) |
4/217. Popliteal venous aneurysm mimicking a soft tissue tumour. A case report.A case of a giant, thrombosed popliteal venous aneurysm without pulmonary embolism in a 53-year-old woman is reported. Despite thorough preoperative investigation including ultrasound and magnetic resonance imaging, this was misdiagnosed as a benign soft tissue tumour. During the operation the thrombosed venous aneurysm was resected and a vein graft from the contralateral saphenous vein was interposed. Popliteal venous aneurysm is a rare entity, presenting occasionally with local signs and symptoms and more often with pulmonary embolism. The clinician should therefore keep this in mind whenever dealing with a large, soft tissue popliteal fossa mass or looking for the cause of recurrent pulmonary embolism.- - - - - - - - - - ranking = 1.0116425665756keywords = embolism (Clic here for more details about this article) |
5/217. thrombosis of an idiopathic saccular azygos aneurysm.We report a case of a large saccular idiopathic aneurysm of the azygos vein which was discovered totally thrombosed at operation. To our knowledge, such a case of thrombosis occurring in this exceptional aneurysm location has never been previously reported.- - - - - - - - - - ranking = 1keywords = thrombosis (Clic here for more details about this article) |
6/217. Spontaneous closure and thrombosis of a ductal aneurysm in a neonate.The natural history of a ductal aneurysm detected prenatally is presented. Neurologic concerns in the neonate and absence of cardio-respiratory compromise permitted serial echo demonstration of constriction, thickening and subsequent closure with formation of thrombus in the aneurysm.- - - - - - - - - - ranking = 4keywords = thrombosis (Clic here for more details about this article) |
7/217. A case of extra-hepatic portal vein aneurysm: evaluation by 3-dimensional computerized tomography angiogram.portal vein aneurysms (PVAs) are rare lesions associated with congenital vascular anomalies or chronic portal hypertension. Although usually benign, they occasionally lead to complications such as aneurysmal rupture, porto-systemic shunts, mural thrombosis in the portal vein, and compression of the biliary tract. So far, the diagnosis of these lesions has been dependent on 2-dimensional imaging modalities such as computed tomography (CT) or magnetic resonance imaging (MRI), or invasive procedures such as percutaneous transhepatic portography. Here we present the first documented case of an extra-hepatic portal vein aneurysm evaluated by 3-dimensional CT angiography. This easily performed and accurate imaging technique may obviate the need for invasive angiographic procedures in the future for the 3-dimensional characterization of deep vascular malformations in the portal circulation.- - - - - - - - - - ranking = 1keywords = thrombosis (Clic here for more details about this article) |
8/217. Popliteal venous aneurysms. Report of a case and review of the literature.Venous aneurysms are uncommon in the vascular pathology of the lower limb. They are more commonly encountered in the neck, thoracic veins and visceral veins. Involvement of the popliteal veins is not often encountered. These aneurysms often cause thrombosis and subsequently pulmonary embolism. phlebography and duplex scanning give the most accurate diagnosis. As the risk of associated pulmonary embolism is high, elective surgery is recommended since it has been proven that proper anticoagulation treatment does not prevent the risk of pulmonary embolism.- - - - - - - - - - ranking = 2.0116425665756keywords = thrombosis, embolism (Clic here for more details about this article) |
9/217. Aortic pseudoaneurysm after ligation of aneurysmal saphenous vein graft.After an aneurysmal saphenous vein graft was ligated and divided at reoperation, the proximal stump continued to enlarge, rather than occluding by thrombosis, producing an aortic pseudoaneurysm that compressed adjacent cardiac structures. Oversewing the aortosaphenous junction of ligated vein graft remnants will prevent this complication.- - - - - - - - - - ranking = 1keywords = thrombosis (Clic here for more details about this article) |
10/217. Internal carotid artery aneurysm visualized during successful endovascular treatment of carotid embolism.We herein present a case of an internal carotid artery embolism associated with a hidden internal carotid artery aneurysm. The aneurysm was visualized during successful endovascular treatment of the carotid embolism. In retrospect, the aneurysm was at risk of rupture during the procedure. In the endovascular treatment of cerebral embolism, the possibility that aneurysms are hidden by emboli must be borne in mind. Care should be taken not to injure unidentified arterial walls while advancing a catheter blindly.- - - - - - - - - - ranking = 2.3604993220097keywords = embolism (Clic here for more details about this article) |
