Budd Chiari syndrome and pericaval filariasis.

ABSTRACT

A young girl presented with Budd-Chiari syndrome (BCS) with narrowing of the retrohepatic segment of inferior vena cava (VC). Dorsal cavoatrial bypass (DCAB) was unsuccessful due to thrombotic occlusion of the graft. A limited autopsy revealed occlusion of the retrohepatic segment of IVC and the terminal parts of the three major hepatic veins. Caval occlusion was just above the level of the superior hepatic veins, and caused by a transverse fibrous shelf. An adult filarial worm was found amidst pericaval fibrosis. Filariasis should be included as a possible aetiological factor in chronic BCS.
