Diagnosis and management of the Budd-Chiari syndrome

Occlusion or obstruction of hepatic venous outflow results in the Budd-Chiari syndrome. The disorder should be suspected in any patient who suddenly develops massive ascites, and the diagnosis can be confirmed quickly and accurately by hepatic venography. In the absence of surgical intervention, survival is rare. Inferior venacavography and percutaneous liver biopsy can be performed safely in these patients, and both procedures provide useful information for the selection of appropriate surgical therapy. Most cases of the Budd-Chiari syndrome are amenable to mesocaval or mesoatrial shunting. Those patients with documented cirrhosis or fulminant hepatic failure are best managed by orthotopic liver transplantation.
