Inferior vena cava graft-enteric fistula after extended hepatectomy with caval replacement.

A case of an inferior vena cava (IVC) graft-enteric fistula manifesting with recurrent sepsis 11 years after a right hepatectomy extending to segments I and IV, the extrahepatic bile duct, and IVC followed by chemotherapy and external-beam radiation therapy is described. A preoperative workup revealed graft thrombosis with air bubbles inside the lumen. Laparotomy found a chronic fistula between the graft and the enteric biliary loop. Removal of the graft without further vascular reconstruction, a take-down of the biliary loop, and a redo hepaticojejunostomy were performed successfully. The diagnostic challenges, possible etiology, and therapeutic implications of this case are discussed.
