Budd-Chiari syndrome merits specific attention, though a discussion of the entire syndrome is beyond the scope of this article. The essentials of this condition as they relate to IVCT are important. Patients typically have significant ascites, portal hypertension, hepatomegaly, collateral vein enlargement, and hepatic fibrosis. The pathophysiology of this syndrome centers on either IVC or hepatic venous thrombosis. If it is at the hepatic venous level, two or three of the major hepatic veins must be occluded before the syndrome can develop. Both hypercoagulable states and membranous venous webs have been postulated as the etiologic agents of Budd-Chiari syndrome.
