This early clinical experience of members of the New England Society for Vascular Surgery with expanded polytetrafluoroethylene (PTFE) grafts was evaluated. Questionnaires were distributed to 52 active members of the Society and 32 answers were received. A total of 186 graft insertions were evaluated, of which 112 were positioned in the lower limb; 106 grafts were inserted for libm salvage. Patency rates for femoral-popliteal bypass grafts were determined by life-table analysis. Our results show a 6 to 9 month cumulative patency rate of 91% for PTFE grafts with a popliteal anastomosis above the knee, and a 52% patency rate for below-knee anastomosis. Two complications, aneurysmal dilatation and graft sepsis, were noted in this series. The new graft material exhibits an early patency rate higher than bovine or Dacron grafts which warrants long-term use and evaluation.
对新英格兰血管外科学会成员使用膨体聚四氟乙烯（PTFE）移植物的早期临床经验进行了评估。向该学会的52名活跃成员发放了问卷，共收到32份回复。总共评估了186例移植物植入情况，其中112例位于下肢；106例移植物植入是为了挽救肢体。通过寿命表分析确定股-腘动脉旁路移植术的通畅率。我们的结果显示，膝关节以上腘动脉吻合的PTFE移植物6至9个月的累积通畅率为91%，膝关节以下吻合的通畅率为52%。本系列中记录了两种并发症，即动脉瘤样扩张和移植物感染。这种新型移植物材料的早期通畅率高于牛源或涤纶移植物，值得长期使用和评估。
