Budd-Chiari syndrome is an uncommon condition induced by thrombotic or nonthrombotic obstruction of the hepatic venous outflow and is characterized by hepatomegaly, ascites, and abdominal pain. [49] See the image below.

The prognosis is poor in patients with Budd-Chiari syndrome who remain untreated, with death resulting from progressive liver failure in 3 months to 3 years from the time of the diagnosis. [1] Following portosystemic shunting, however, the 5-year survival rate for patients with the syndrome is 38-87%. The actuarial 5-year survival rate following liver transplantation is 70%. [2, 3, 4]
