Budd-Chiari syndrome with thrombosis of the inferior vena cava: long-term patency of meso-caval and cavoatrial prosthetic bypass.

Portacaval or mesocaval shunts may relieve ascites that is caused by chronic forms of primary Budd-Chiari syndrome. When inferior vena cava stenosis is severe or is the site of thrombosis, another procedure has to be used. Portoatrial or cavoatrial shunting has been suggested, and a few reports have been made after only a short follow-up period. The case of a young woman with long-standing ascites caused by primary occlusion of the hepatic veins illustrates the incomplete relief of ascites after mesocaval shunt, which was caused by severe stenosis of the inferior vena cava. At 2 1/2-year follow-up, thrombosis of the retrohepatic inferior vena cava was documented and the mesocaval shunt remained patent. Cavoatrial bypass performed with the use of a long Dacron graft was successful as noted at a 4 1/2-year postoperative follow-up, and there was angiographic proof of patency. Budd-Chiari syndrome with stenosis or thrombosis of the inferior vena cava may be cured by prosthetic bypasses to the right atrium. Combined mesocaval and cavoatrial shunt should be encouraged in this specific situation.
