This report describes two non-cirrhotic patients with portal vein thrombosis who underwent successful balloon occlusion retrograde transvenous obliteration (BRTO) of gastric varices with a satisfactory response and no complications. One patient was a 35-year-old female with a history of Crohn's disease, status post-total abdominal colectomy, and portal vein and mesenteric vein thrombosis. The o...

HCC has a high propensity to invade into the portal vein by direct venous extension or metastasis, which may cause tumor thrombosis that occurs in up to 70% of patients. It is well recognized that Portal Vein Tumor Thrombosis (PVTT) is a major detrimental prognosticator in HCC and almost all staging or prognostic systems for HCC include PVTT as an important parameter. Herein, we reported an int...

Vitelline veins are a pair of embryonic structures. The veins develop the portal vein system. Serious problems occur if the vitelline vein does not regress and becomes an aneurysm. Thrombus formation in the vitelline vein aneurysm could lead to portal vein thrombosis and portal hypertension unless promptly and correctly treated. Though vitelline vein aneurysm is an extremely rare anomaly, it ra...

BACKGROUND Factor V Leiden has been reported in 2%-30% of patients with portal vein thrombosis. This wide variation makes it difficult to assess the importance of factor V Leiden as a predisposing factor. METHODS Factor V Leiden was determined by restriction fragment length polymorphism in 112 patients with portal vein thrombosis, 104 with deep vein thrombosis and 98 control subjects. RESUL...

A 64-year-male underwent a liver biopsy based on clinical concern for primary biliary cirrhosis. The biopsy, which yielded normal results, was uneventful, with no immediate postbiopsy complications. A later MRI demonstrated early opacification of the right portal vein on arterial-phase imaging, suggesting communication between the right hepatic artery and the right portal vein. A conservative, ...

Portal vein thrombosis and pancreatico-pleural fistula are unusual complications of chronic pancreatitis. We describe a patient with chronic alcoholic pancreatitis in whom erosion of the splenic vein led to portal vein thrombosis and to the development of a pancreatico-pleural fistula. We suggest that fistula formation may occur over a considerable time period as the portal vein thrombosis was ...

BACKGROUND Portal vein thrombosis is a fairly common and potentially life-threatening complication in patients with liver cirrhosis. The risk factors for portal vein thrombosis in these patients are still not fully understood. OBJECTIVES This study aimed to investigate the associations between various risk factors in cirrhotic patients and the development of portal vein thrombosis. PATIENTS...

OBJECTIVE To describe the appearance of transient hepatic attenuation differences (THADs) of extrahepatic origin. MATERIALS AND METHODS Five cases of THADs produced by compression of the extrahepatic portal vein at its confluence with the splenic vein were identified prospectively over a four-month period. Two additional cases of peripheral THADs resulting from main portal vein thrombosis wer...
