The use of expanded polytetrafluoroethylene (PTFE) grafts for myocardial revascularization
J Cardiovasc Surg (Torino).
1984 Nov-Dec.
Abstract
In 18 patients necessitating aorto-coronary bypass grafting procedures in whom suitable veins were not available, 22 PTFE grafts were used in combination with 47 saphenous-vein grafts. 14 patients were studied angiographically 1-26 months after operation, with a mean follow-up of 12 months. 59% of the expanded PTFE grafts and 86% saphenous vein grafts were patent. Factors affecting PTFE graft patency were similar to those of vein grafts. We conclude, that it is reasonable to use this artificial prosthesis only when sufficient veins are not available. Expanded PTFE grafts of 3-5 mm diameter can remain patent and functional for more than 2 years.
