Abstract
An animal model simulating the necessity of replacing the inferior vena cava (IVC) with a prosthetic graft is described. Six dogs underwent replacement of the IVC with an expanded polytetrafluoroethylene (E-PTFE) graft using an interrupted-suture technique. Three dogs served as controls, undergoing resection and autograft of the native IVC. Distal side-to-side femoral arteriovenous fistulas were constructed in each case and allowed to remain for six weeks. Subcutaneous heparin and prophylactic antibiotics were administered in the early postoperative period. All grafts were patent at six months, indicating a potentially successful technique for reconstruction of the IVC involved in disease or trauma.
