The hepatic veno-occlusive diseases are a heterogeneous group of circulatory disorders characterized by obstruction of hepatic venous outflow at the sinusoidal or postsinusoidal levels. A large series of patients gave us an opportunity to devise a management protocol for this disorder. The most common cause of Budd-Chiari syndrome (obstruction of hepatic venous outflow) is a clot blocking the hepatic veins and inferior vena cava. In cirrhosis and hepatic malignancies, the thromboses usually begin intrahepatically and spread to the extrahepatic portal vein.
