下肢旁路手术的成功主要取决于自体大隐静脉的可用性，这是迄今为止已知的最令人满意的动脉替代物。虽然各种假体管道，在隐静脉的情况下使用，已显示出良好的短期随访的成功，需要更多的长期比较数据进行充分的评估。本文用寿命表法分析了6年来134例聚四氟乙烯（PTFE）腹股沟下旁路移植术的结果。结果再次证实了静脉旁路的长期通畅性优于人工血管。分析表明，虽然PTFE在即时和短期随访期间可能会产生可接受的结果，但6年通畅率接近20- 30%。
The success of lower limb bypass surgery depends, in the major part, on the availability of autologous saphenous vein as the most satisfactory arterial substitute known to date. Although various prosthetic conduits, used in the absence of saphenous vein, have shown promising success on short term follow-up, more long-term comparative data are required for adequate assessment. This study analyses, by life table method, the results of 134 infra-inguinal bypass grafts using polytetrafluoroethylene (PTFE) over a 6 year period. The results reconfirm the superior long-term patency of vein bypasses compared with such prosthetic grafts. Analysis suggests that, while PTFE may give acceptable results in the immediate and shortterm follow-up period, 6 year patencies approach 20–30 per cent.
