Aortocoronary Bypass Grafting With Expanded Polytetrafluoroethylene: 12-Year Patency

Prosthetic coronary artery bypass conduits are rarely used because the rate of thrombosis is inherently higher than that with autologous conduits. The low medium-term patency rates of prosthetic grafts have restricted their use primarily to patients with inadequate autologous conduits or to selected emergencies. We describe a patient treated with expanded polytetrafluoroethylene who had documented patency 12 years after the operation.
