Hepatic autotransplantation with ex situ neoplasm extirpation and vena cava replacement.

The treatment of a 64-year-old man with a retrohepatic neoplasm deemed not accessible by conventional in situ surgical techniques is presented to illustrate the potential benefit offered by techniques adapted from liver transplantation and vascular surgery. A computed tomography scan performed for uncharacteristic abdominal discomfort revealed a hepatic or retrohepatic tumor compressing the inferior vena cava. Biopsies were interpreted as probably leiomyoma or malignant schwannoma. The liver with neoplasm and retrohepatic inferior vena cava was removed en bloc and taken to the back table where the neoplasm invading the inferior vena cava wall was removed together with the inferior vena cava. The inferior vena cava was then replaced by a 22-mm polytetrafluoroethylene graft and the 3 hepatic veins were reconstructed with anastomoses to this graft. The liver was then autotransplanted by standard transplantation technique. The postoperative course was uneventful and the patient is in good health more than 2 years after surgery.
