OBJECTIVES To evaluate the safety and patency of self-expanding stents to treat hepatic venous outflow obstruction after orthotopic liver transplantation. To evaluate differences in the response between patients with early obstruction and patients with late obstruction. MATERIAL AND METHODS This is a retrospective analysis of 16 patients with hepatic venous outflow obstruction after liver tra...

Hepatic venous drainage in liver transplantation may be reduced to the level of caval anastomosis producing an obstruction degree and leading to serious vascular complication such as the acute Budd-Chiari syndrome, which may result in organ loss. Outflow obstruction may be caused by lack of technique in caval anastomosis or by allograft malposition as a consequence of anatomical graft and recip...

Obstruction of the hepatic venous outflow tract results in increased hepatic sinusoidal pressure and portal hypertension. In the early stages, portal venous perfusion of the liver is decreased, which may result in portal venous thrombosis. 2 The ensuing venous stasis and congestion lead to hypoxic damage to adjacent hepatic parenchymal cells. Furthermore, the ischemic injury to the sinusoidal l...

the budd–chiari syndrome (bcs) is a rare disorder caused by the obstruction of the hepatic veins or the inferior vena cava (ivc) at the suprahepatic level. this syndrome is developed by either hepatic vein thrombosis or mechanical venous obstruction and leads to centrilobular hepatic congestion with the subsequent development of fibrosis and cirrhosis. intracardiac tumors have been rarely repor...

Portal hypertension is the commonest cause of upper gastrointestinal bleeding in children and up to 30% of cases with upper gastrointestinal hemorrhage can be fatal. Extrahepatic portal venous obstruction (EHPVO) is the commonest cause of portal hypertension in children and also one of the common causes in adults in India and other tropical countries (Arora, 1998; Poddar, 2008; Poddar 2000). In...

Dilatation of the azygos-hemiazygos venous system presenting as paravertebral masses may be seen in intrahepatic and extrahepatic portal vein obstruction, anomalous pulmonary venous return, occlusion of the superior and inferior vena cava, persistence of the left superior vena cava, hepatic vein obstruction, elevation of central venous pressure as in congestive heart failure, pericardial effusi...

Diffuse involvement of the liver with neoplastic processes can present a diagnostic dilemma. We present the case of a diffusely infiltrative neuroendocrine tumor (NET) that mimicked Budd-Chiari syndrome (BCS), not previously described in the literature. Histological evaluation can be limited without well-defined margins. Only one of two biopsies revealed a NET. A diagnosis of BCS was first cons...

Budd-Chiari Syndrome is an uncommon condition characterized by clinical features related to hepatic venous outflow obstruction resulting either from thrombotic or non-thrombotic causes. Presentations may vary asymptomatic acute fulminant failure. A meticulous history, examination and imaging studies are invaluable for a prompt diagnosis initiation of time-sensitive treatment. This report presen...

BACKGROUND The clinical pattern and long-term course of chronic inferior vena cava (IVC) obstructions are variable and depend on the underlying cause, the segment involved, and the extension of secondary thrombosis. Pertinent data on IVC obstructions in well-defined series of patients are lacking. We report the sequelae of chronic IVC obstructions in the hepatic segment in 11 consecutive patien...

budd-chiari syndrome is caused by the obstruction of the hepatic venous, with high mortality rate in nontreated cases. because the clinical presentation of this syndrome is nonspecific, is very important. contrast enhanced multiphase computed tomography (ct) and magnetic resonance (mr) angiography permits morphologic and functional assessment of liver changes in suspicious clinical setting. the...
