Inferior vena cava obstruction in Budd-Chiari syndrome: successful treatment by radiological stenting followed by a portosystemic shunt.

摘要

Surgical decompression by a portosystemic shunt in Budd-Chiari syndrome depends on the caval state. Obstruction of the inferior vena cava (IVC) precludes such an operation due to the risk of reduced blood flow across the shunt and subsequent thrombosis. Similar risks are encountered in more complicated operations such as mesoatrial shunt. We report a patient with Budd-Chiari syndrome in whom obstruction of the intrahepatic IVC by a hypertrophied caudate lobe of the liver precluded the construction of a standard portocaval shunt. A two-step procedure with preoperative radiological stenting of the narrowed IVC followed by a portocaval shunt was successfully performed. This is the fifth case reported in the literature of such an approach.
