1/78. Arterial imaging.angioscopy, magnetic resonance angiography, computed tomography, and nuclear medicine are assuming an increasingly important role in arterial imaging. This review discusses recent advances in these modalities. angioscopy has proven valuable in monitoring intraoperative surgical procedures as well as percutaneous interventions. Carotid artery magnetic resonance angiography is gaining increasing acceptance in clinical practice. magnetic resonance angiography of the peripheral arteries is limited by spatial resolution and signal loss distal to the stenosis. The role of computed tomography in limiting the number of aortograms performed in evaluating aortic laceration remains controversial; however, several recent papers indicate its usefulness in evaluating clinically stable patients with abnormal chest radiographs. Computed tomography of abdominal aortic aneurysms may obviate the need for preoperative aortography in the majority of cases. Nuclear imaging for deep venous thrombosis using 111In-labeled antifibrin monoclonal antibodies was shown highly sensitive in its initial report.- - - - - - - - - - ranking = 1keywords = aneurysm (Clic here for more details about this article) |
2/78. Inferior vena cava hypoplasia with intrahepatic venous continuation: sonographic, angiographic and MR features including MR angiography.In cases of inborn or acquired obstacles on the inferior vena cava (IVC), the derived blood flow usually goes through collaterals in the azygos or the hemiazygos venous systems. Exceptionally, a collateral pathway through the portal system or through an anastomosis in between hepatic veins, shunting the IVC interruption, is encountered. In the present paper, the authors describe the fortuitous discovery of a IVC hypoplasia in its retrohepatic segment. MR venography, correlated with fluoroscopic angiography, clearly depicted an intrahepatic collateral circulation consisting of a double aneurysmal communication between an inferior right hepatic vein and the main right hepatic vein.- - - - - - - - - - ranking = 1keywords = aneurysm (Clic here for more details about this article) |
3/78. Bilateral radial artery pseudoaneurysms associated with bilateral ulnar artery atresia: a case report.Pseudoaneurysms of the radial artery are uncommon and most often localized in an area of penetrating vascular trauma or iatrogenic injury. Hypoplasia of the ulnar artery is even more rare. We report a case of bilateral radial artery pseudoaneurysms associated with complete absence of any ulnar contribution to the vascularity of the hand. A patient presented with bilateral tender masses adjacent to the anatomic snuff boxes that interfered with hand function. After confirming that these masses were bilateral radial artery pseudoaneurysms, resection of the pseudoaneurysms and microscopic reconstruction of the arterial segments preserved vascular integrity of the hands and provided relief of the patient's pain.- - - - - - - - - - ranking = 12.262402174803keywords = aneurysm, pseudoaneurysm (Clic here for more details about this article) |
4/78. Intraoesophageal rupture of a thoracic aortic aneurysm.The intraoesophageal rupture of a large thoracic aortic aneurysm is reported in a 49 year old man. He had been hypertensive for some years while the aneurysm increased in size. Although a graft was successfully inserted to repair the leak, infection from the oesophagus with candida albicans, subsequently led to secondary haemorrhage and death 17 days later. A plea is made for the earlier referral of patients with aneurysm prior to rupture, as the operative mortality rises markedly after rupture has occurred and in this case the situation was virtually irreparable.- - - - - - - - - - ranking = 7keywords = aneurysm (Clic here for more details about this article) |
5/78. Endovascular repair of traumatic pseudoaneurysm by uncovered self-expandable stenting with or without transstent coiling of the aneurysm cavity.Various surgical options for internal carotid or subclavian artery pseudoaneurysm repair have been reported; however, in general they have resulted in poor outcomes with high morbidity and mortality rates. Recently, these open surgical procedures have been partly replaced by percutaneous transluminal placement of endovascular devices. We evaluated the potential for using flexible self-expanding uncovered stents with or without coiling to treat extracranial internal carotid, subclavian and other peripheral artery posttraumatic pseudoaneurysm. Three patients with posttraumatic pseudoaneurysm were treated by stent deployment and coiling (two cases) of the aneurysm cavity. In one case, a 5.0 x 47 mm Wallstent (boston Scientific) was positioned to span the neck of the 9 x 5 mm size pseudoaneurysm (left internal carotid artery) and deployed. Angiography demonstrated complete occlusion of the pseudoaneurysm without coiling. In the second patient, a 5.0 x 31 mm Wallstent (boston Scientific) was positioned to span the neck of the 9 x 7 mm size pseudoaneurysm (right internal carotid artery) and deployed. A total of six coils (Guglielmi Detachable Coils, boston Scientific) were deployed into the pseudoaneurysm cavity until it was completely obliterated. In the third case, an 8.0 x 80 mm SMART (Cordis) stent was advanced over the wire, positioned to span the neck of the 10 x 7 mm size pseudoaneurysm of the left subclavian artery, and deployed. Fourteen 40 x 0.5 mm Trufill (Cordis) pushable coils were deployed into the pseudoaneurysm cavity until it was completely obliterated. At long-term follow-up (6-9 months), all patients were asymptomatic without flow into the aneurysm cavity by Duplex ultrasound. We conclude that uncovered endovascular flexible self-expanding stent placement with transstent coil embolization of the pseudoaneurysm cavity is a promising new technique to treat posttraumatic pseudoaneurysm vascular disease by minimally invasive methods, while preserving the patency of the vessel and side branches.- - - - - - - - - - ranking = 30.133718946006keywords = aneurysm, pseudoaneurysm (Clic here for more details about this article) |
6/78. Local vascular complications after knee replacement: a review with illustrative case reports.The incidence of vascular complications after knee replacement is between 0.03% and 0.2%. These complications include acute ischaemia, thrombosis, haemorrhage, fistula and aneurysm formation. Vascular complications can be avoided by careful pre-operative selection. If doubt exists, a vascular opinion should be obtained before knee replacement. In the event of a vascular complication occurring, serious morbidity can be avoided by prompt diagnosis, investigation and specialist treatment.- - - - - - - - - - ranking = 1keywords = aneurysm (Clic here for more details about this article) |
7/78. Arterial dysplasia with ruptured basilar artery aneurysm: report of a case.An 11 year old girl died unexpectedly as a result of spontaneous subarachnoid hemorrhage originating from a ruptured giant fusiform aneurysm of the basilar artery. The aneurysm had developed as a long standing complication of arterial fibromuscular dysplasia. This discussion describes the light and electron microscopic findings in the aneurysm and the histologic examination of abnormalities in the muscular arteries of the viscera.- - - - - - - - - - ranking = 7keywords = aneurysm (Clic here for more details about this article) |
8/78. Embolization in a patient with ruptured anterior inferior pancreaticoduodenal arterial aneurysm with median arcuate ligament syndrome.In median arcuate ligament syndrome, the root of the celiac artery is compressed and narrowed by the median arcuate ligament of the diaphragm during expiration, causing abdominal angina. Aneurysm may be formed in arteries of the pancreas and duodenum due to a chronic increase in blood flow from the superior mesenteric artery into the celiac arterial region. We report a patient saved by embolization with coils of ruptured aneurysm that developed with markedly dilated anterior inferior pancreaticoduodenal artery due to median arcuate ligament syndrome.- - - - - - - - - - ranking = 5keywords = aneurysm (Clic here for more details about this article) |
9/78. Arteriomegaly.Arteriomegaly describes tortuous, ectatic, irregular vessels with prolonged blood flow. Seven cases of this entity are outlined with representative case reports. The increased incidence of aneurysms, thrombosis and embolization is noted in this and other series. The possibility that tortuous vessels may be confused with aneurysms on examination is also discussed. Due to the prolongation of blood flow, adequate arteriographic evaluation may be quite difficult.- - - - - - - - - - ranking = 2keywords = aneurysm (Clic here for more details about this article) |
10/78. Vascular involvement in Behcet's disease. Two case reports.Arterial involvement is rare in Behcet's disease but can be at the forefront of the clinical picture and cause life-threatening complications. case reports: A 36-year-old man had Behcet's disease with an aortographically documented aneurysm of the abdominal aorta as the inaugural manifestation. He had oral and genital ulcers. Funduscopy showed periphlebitis. In a 38-year-old man with an 8-year history of Behcet's disease, pulmonary and coronary artery aneurysms developed, as well as intracardiac and venous thromboses. DISCUSSION: Arterial involvement occurs in 3-5% of patients with Behcet's disease and usually manifests as multiple spindle-shaped aneurysms. Intracardiac thrombosis and cardiac aneurysm are exceedingly rare. Our patient had an extremely unusual presentation given the low rate of occurrence of arterial lesions in Behcet's disease. CONCLUSION: Arterial involvement in Behcet's disease raises treatment challenges because the lesions tend to recur and can cause life-threatening complications.- - - - - - - - - - ranking = 4keywords = aneurysm (Clic here for more details about this article) |
