[Diagnosis and treatment of Budd-Chiari syndrome].

The etiology and pathology of Budd-Chiari syndrome (BCS) remain unclear. The membrane in some membranous BCS may be derived from the absorption and organization of the thrombus of inferior vena cava (IVC). The long-term efficacies of currently available graft shunt operations are unsatisfactory. Interventional therapy or radical resection of lesion should be recommended. The IVC stenosis actually results from the compression of hepatomegaly and should not be classified as BCS. The membranous BCS is an acquired disease.
