Portoatrial shunt in Budd-Chiari syndrome

It is now well accepted that mesoatrial bypass is an efficient treatment of Budd-Chiari syndrome and that it is indicated when the inferior vena cava is obstructed. This report presents a patient in whom the superior mesenteric vein was thrombosed after a previous mesocaval shunt. A bypass was constructed between the left side of the portal vein and the right atrium with a 16 mm diameter reinforced polytetrafluoroethylene prosthesis. The prosthesis passed between the left lobe of the liver and the caudate lobe and had a direct trajection. The procedure was simple, the postoperative course was uneventful, and the patient was well 20 months later. This observation suggests that portoatrial shunt is a good alternative to mesoatrial shunts in patients with Budd-Chiari syndrome and unavailable inferior vena cava and superior mesenteric vein.
