budd-chiari syndrome (bcs) refers to thrombosis of hepatic veins as well as intrahepatic or suprahepatic inferior vena cava. we present for the first time a case of possible occurrence of budd- chiari syndrome with the history of depot medroxy progesterone acetate (dmpa) injections in a 33-yearold iranian woman. an underlying disorder can be identified in most of patients with bcs. many of thes...

essential thrombocythemia is a chronic myeloproliferative disorder characterized by a sustained proliferation of megakaryocytes, which leads to increased numbers of circulating platelets. hemorrhagic and/or thrombotic episodes are frequent, and thrombosis of both veins and arteries may develop. vessels in unusual sites may be involved, e.g., the hepatic veins, mesenteric veins, and the digital ...

Venous thrombophilia is the result of clotting changes namely of a hypercoagulable state together with blood flow and vessel wall changes. There is no need for all these components to be present in order for thrombosis to occur. As the matter of fact, thrombosis may occur even if only one of these conditions is present. In clinical practice a combination of factors is usualy seen. In comparison...

PURPOSE To evaluate and model the risk of in vivo thrombosis in each hepatic vessel type during hepatic microwave ablation as a function of vessel diameter, velocity, and vessel-antenna spacing. MATERIALS AND METHODS A single microwave ablation antenna was inserted into a single porcine lobe (n = 15 total) adjacent to a hepatic artery, hepatic vein, or portal vein branch. Conventional ultraso...

the goal of this study was to define the normal range of diameter in the deep vein of the lower limb and to compare this range with diameter of the veins with acute thrombosis and of veins with chronic thrombosis by using color doppler sonography. the study was cross sectional. the vein diameter and vein to artery ratio in different levels were measured and the following results were obtained. ...

Inferior vena caval obstruction occurs not infrequently. In 1911 Pleasants reviewed 314 published cases of which 68 per cent. were due to thrombosis, I6 per cent. to external pressure and I6 per cent. to invasion by neoplasm. Where it is due to thrombosis this is usually due to spread from veins in the legs and pelvis. In most cases the thrombosis is confined to the lower part of the inferior v...

To discuss the clinical presentation, diagnosis, and treatment of hepatic venous outflow obstruction as a complication of polycystic liver disease, four cases diagnosed and treated at our institution have been reviewed and the information from six previously published case reports has been summarized. Eight of the 10 patients were women. All presented with severe ascites. Nine had polycystic ki...
