1/183. Angioplasic surgery for renal artery aneurysm in pediatric hypertension.Aneurysmectomy and renal angioplasty were performed on a 14-year-old Japanese male and the blood pressure was within normal values 3 years after this surgery. Measurement of renal blood flow was facilitated by using 133Xe washout technique. This incidence is the eighth such case to be reported from japan.- - - - - - - - - - ranking = 1keywords = hypertension (Clic here for more details about this article) |
2/183. splenic artery aneurysm and orthotopic liver transplantation.splenic artery aneurysms are a rare but potentially fatal complication after liver transplantation. We report three cases presenting in a 12-month period in adult patients who underwent transplantation for chronic liver disease. Doppler ultrasound of the splenic artery should be performed in all patients with cirrhosis and portal hypertension who are being assessed for liver transplantation. The aneurysm can be ligated at the time of transplantation.- - - - - - - - - - ranking = 0.25keywords = hypertension (Clic here for more details about this article) |
3/183. splenic vein aneurysm: is it a surgical indication?splenic vein aneurysms are rare and are usually caused by portal hypertension. Symptoms are unusual, but may include rupture or abdominal pain. diagnosis can usually be made either by means of duplex ultrasonography or computed tomography scanning. Treatment varies from noninvasive follow-up to aneurysm excision. We report an expanding splenic vein aneurysm in a young woman with abdominal and back pain and no history of portal hypertension. She was treated with aneurysm excision and splenectomy.- - - - - - - - - - ranking = 0.5keywords = hypertension (Clic here for more details about this article) |
4/183. Ask-Upmark kidney associated with renal and extrarenal arterial aneurysms.Reports of Ask-Upmark kidney, initially described as a congenital defect in renal development, are uncommon. We report a case with the features of bilateral asymmetrical segmental atrophy in a patient with childhood-onset hypertension. As an adult, she developed cerebral, celiac, and renal artery aneurysms. She underwent successful clipping of the cerebral aneurysm and renal artery repair with preservation of renal function. Novel radiologic techniques make possible the noninvasive diagnosis of segmental atrophy and its complications.- - - - - - - - - - ranking = 0.25keywords = hypertension (Clic here for more details about this article) |
5/183. Portal venous system aneurysms: report of five cases.Until recently aneurysms in the portal venous system were considered to be very rare lesions. This opinion has largely been changed by the increasing number of cases reported in recent years. In this paper we report the cases of five patients with portal venous system aneurysms, including one with splenic vein aneurysm. One patient had associated portal hypertension. The reexamination of two patients 2 years later showed no change in the aneurysms. The sonographic features and related literature are reviewed. In the light of this series and the information in the literature, we recommend that portal venous system aneurysms should no longer be considered exceptionally rare entities.- - - - - - - - - - ranking = 0.25keywords = hypertension (Clic here for more details about this article) |
6/183. Functional, life-threatening disorders and splenectomy following liver transplantation.splenectomy (SPL) in cirrhotic patients undergoing liver transplantation (LTx) may resolve specific problems related to the procedure itself, in case of functional and life-threatening clinical situations often occurring as a result of liver cirrhosis and portal hypertension. METHOD: A single-center experience of ten splenectomies in a series of 180 consecutive adult liver transplant patients over a period of 6 yr is reported. The mean patient age was 46.8 /- 9.5 yr (range 25 57 yr). Indications for SPL were post-operative massive ascitic fluid loss (n = 3), severe thrombocytopenia (n = 3), acute intra-abdominal hemorrhage (n = 2), infarction of the spleen (n = 1), and multiple splenic artery aneurysms (n = 1). RESULTS: Extreme ascites production due to functional graft congestion disappeared post-SPL, with an improvement of the hepatic and renal functions. SPL was also effective in cases of thrombocytopenia persistence post-LTx, leading to an increase in the platelet count after about 1 wk. Bleeding episodes related to left-sided portal hypertension or trauma were also resolved. The rejection rate during hospitalization was 0%, and no other episodes were recorded in the course of the long-term follow-up. However, sepsis with a fatal outcome occurred in 4 patients, i.e. between 2 and 3 wk post-SPL in three cases and 1 yr after the procedure as a result of pneumococcal infection in the last case. Fatal traumatic cranial injury occurred 3 yr post-LTx in another case. Five patients (50%) are still alive and asymptomatic after a median follow-up period of 36 months. CONCLUSION: The lowering of the portal flow appears to resolve unexplained post-operative ascitic fluid loss as a result of functional graft congestion following LTx. However, because of the enhanced risk of SPL-related sepsis, a partial splenic embolization (PSE) or a spleno-renal shunt could be used as an alternative procedure because it allows us to preserve the immunological function of the spleen. SPL is indicated in case of post-transplant bleeding due to left-sided portal hypertension and trauma, spleen infarction, and to enable prevention of hemorrhage in liver transplant patients with multiple splenic artery aneurysms. Severe and persistent thrombocytopenia could be treated with PSE. Because the occurrence of fatal sepsis post-SPL is a major complication in LTx, functional disorders, such as ascites and thrombocytopenia, should be treated with a more conservative approach.- - - - - - - - - - ranking = 0.75keywords = hypertension (Clic here for more details about this article) |
7/183. 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 = 0.25keywords = hypertension (Clic here for more details about this article) |
8/183. Balloon-assisted coil embolization for large-necked renal artery aneurysms.An aneurysm of the right renal artery was discovered in a patient suffering from cerebral arterial angiodysplasia and arterial hypertension. The aneurysm was large necked, which made selective endovascular treatment very difficult. To perform the embolization of the aneurysm, a balloon remodelling technique was used. This prevented migration of coils within the arterial lumen.- - - - - - - - - - ranking = 0.25keywords = hypertension (Clic here for more details about this article) |
9/183. Untreated idiopathic aneurysm of the pulmonary artery; long-term follow-up.A 57-year-old man with an idiopathic aneurysm of the left pulmonary artery is presented. The aneurysm was stable over many decades. No such long-term follow-up of an idiopathic pulmonary aneurysm has been described previously. After 39 years there is no evidence of heart failure or pulmonary hypertension. Because corrective surgery has a variable outcome, and prognosis is suggested to be good in the idiopathic form of pulmonary aneurysm, no surgical correction was proposed.- - - - - - - - - - ranking = 0.25keywords = hypertension (Clic here for more details about this article) |
10/183. Aneurysmal dilatation of the paraumbilical vein in an infant.The paraumbilical veins are one of the most common collateral pathways developing in portal hypertension. Aneurysmal dilatation of a patent paraumbilical vein is a very unusual finding. We report the first infant case of a paraumbilical vein aneurysm and its Doppler ultrasound findings.- - - - - - - - - - ranking = 0.25keywords = hypertension (Clic here for more details about this article) |
