1/26. aneurysm of the pancreaticoduodenal artery. A case report.A case of an aneurysm of the pancreaticoduodenal artery is reported, together with a short review of the literature relating to this condition Because of its rarity the diagnosis is often overlooked even when typical changes are found on X-ray. The possible relationship between obstructive jaundice and aneurysms in the vicinity of the galltree is discussed. Surgical treatment is recommended by most authors once the diagnosis of an intra-abdominal aneurysm has been made, mainly because of the risk of rupture.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
2/26. portal vein aneurysm.While there have been a few references to portal vein aneurysm in the world literature, this is the first report in united states radiologic literature. During a routine evaluation for fever in one patient, an ultrasound examination suggested this unusual entity at the junction of the splenic and superior mesenteric vein. It was later confirmed by angiography. Two other patients were being investigated angiographically for gastrointestinal bleeding when portal vein aneurysms were discovered. In contrast to the central location of the first patient's aneurysm, the latter two were more distal in the portal tree. The literature is reviewed and different etiologic hypothesis discussed.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
3/26. Surgical repair of a solitary deep femoral arterial aneurysm: report of two cases.We report herein two cases of a solitary deep femoral arterial aneurysm that were successfully treated by aneurysmectomy and ligation of the deep femoral artery. The patients were a 69-year-old man and a 73-year-old man, both of whom presented with localized pain and a pulsatile mass in the femoral area showing rapid enlargement. ultrasonography and arteriography confirmed the diagnosis and revealed no evidence of aneurysm or occlusive disease in the other arteries. Aneurysmectomy and ligation of the deep femoral artery were performed, and no ischemic symptoms or thrombus developed postoperatively in either patient. Preoperative arteriography is essential to delineate not only the state of the aneurysm, but also that of the distal arterial tree. An emergency operation is also mandatory due to the rapid enlargement of this type of aneurysm, even if rupture occurs.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
4/26. Autologous blood clot embolization into a bleeding renal artery pseudoaneurysm.A young girl suffering from anuria due to periarteritis nodosa developed severe bleeding after left kidney needle biopsy. angiography revealed, in addition to changes in the renal vascular tree, two saccular pseudoaneurysms in the course of a lobar artery in the left kidney. These caused life-threatening bleeding from the urinary tract. An autologous blood clot was injected into the bleeding artery by selective catherization, which resulted in cessation of bleeding for a period of 15 h, and thus permitted the performance of surgical intervention - nephrectomy - under more suitable conditions.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
5/26. Acquired arterial macroaneurysms of the retina.Fifteen patients with acquired arterial macroaneurysms of the retina, and an additional woman patient with some 18 aneurysms of the temporal retinal arterial tree of one eye, are described. Acquired aneurysms occur in patients in their sixth decade and older, are usually unilateral, and occur on the major arterial branches posterior to the equator. Customarily only one or two aneurysms are present. Most patients have a history of poorly controlled systemic hypertension or a raised blood pressure at the time of discovery of the macroaneurysm. Focal embolic damage to arterial walls should be considered in the investigation of these patients. In patients with decreased vision from macular oedema and circinate retinopathy, photocoagulation of the macroaneurysm may hasten the improvement in visual acuity.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
6/26. Multiple aneurysms in childhood.Arterial aneurysms in children are rare. When present, they are often associated with connective tissue disorders or arteritidies. Idiopathic aneurysms occurring at multiple sites throughout the arterial tree are rare, with only ten cases reported. This report describes a case of multiple arterial aneurysms of uncertain origin involving upper-extremity, extracranial cerebrovascular, aortoiliac, and renal arteries in a 14-year-old boy. The clinical presentation, vascular reconstruction, pathologic findings, and a brief review of the literature are described.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
7/26. Percutaneous management of a hepatic artery aneurysm: bleeding after liver transplantation.In this article we present an unusual case of hepatic artery aneurysm bleeding due to a hepatic artery thrombosis after liver transplantation. The patient developed a recurrent hepatic artery thrombosis leading to severe graft failure in four consecutive liver transplantations. While being evaluated for a fifth transplant, stabilization of the clinical situation was attempted by interventional therapy. The first intervention was to place a stent into the hepatic artery to prevent further ischemic damage. This failed to improve graft function, but unfortunately led to the development of a pseudoaneurysm at the distal end with a subsequent rupture into the biliary tree. Bleeding was treated successfully by direct puncture and coil embolization of the aneurysm. In addition, the patient demonstrated a hemodynamically relevant portal vein stenosis on the CT scan. Stenting of the portal vein markedly improved graft function. After extensive investigations, a paroxysmal nocturnal hemoglobinuria was found to be the underlying cause of the recurrent hepatic artery thrombosis. Here we suggest that hepatic artery aneurysm bleeding is a rare but potentially fatal complication that can be successfully treated by percutaneous coil embolization. Additionally, we propose that stenting of the portal vein can lead to a significant improvement of the graft perfusion even though the hepatic artery remained occluded.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
8/26. Selective embolisation of intrahepatic aneurysms.The radiological techniques that can be used to selectively embolise small arteries have improved markedly in the past few years. This article discusses the use of transcatheter embolisation in the management of three patients with aneurysms involving the intrahepatic arterial tree.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
9/26. Deep femoral artery aneurysm presenting as lower limb swelling: a case report.We report a rare case of lower limb swelling due to compression of the superficial femoral vein by a solitary deep femoral artery aneurysm. The patient was a 58-year-old man presenting with acute swelling of the right lower limb caused by deep venous thrombosis. A multi-detector computed tomographic scan (CT) confirmed the diagnosis of a deep femoral artery aneurysm and revealed no evidence of aneurysms or occlusive lesions in the other arteries. Aneurysmectomy and ligation of the deep femoral artery were successfully performed. Preoperative multi-detector CT scanning is a valuable, non-invasive diagnostic tool to delineate not only the state of the aneurysm, but also that of the distal arterial tree.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
10/26. Primary vascular occlusion in IRVAN (idiopathic retinal vasculitis, aneurysms, neuroretinitis) syndrome.IRVAN is a rare retinal vascular disease characterized by the presence of aneurysmal dilations along the retinal arteriolar tree. Visual loss occurs from sequelae to proliferative changes or due to severe macular exudation and rarely from secondary vascular occlusion following laser photocoagulation of the aneurysms. We herein report a patient with a primary vascular occlusion in a patient with IRVAN and suggest that such patients may already have a natural predisposition to develop a vascular occlusion.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
