title: Surgical principles and polytetrafluoroethylene.
abstract: This report describes a 24-month follow-up in 100 consecutive polytetrafluoroethylene (PTFE) arterial grafts. Although initial results were superb, a continued follow-up has showed extremely high closure rates for femoropopliteal and femorotibial grafts. The primary reason for this high attrition rate is thought to be stasis. We believe that PTFE is clearly the best synthetic arterial replacement available, but the material does not approach the autogenous saphenous vein in terms of long-term patency. Therefore, in spite of its many advantages, we do not recommend the elective use of PTFE for peripheral small-vessel bypass.
