Twenty-seven externally supported polytetrafluoroethylene (PTFE) grafts were implanted in the femoropopliteal position crossing the knee joint. All patients underwent surgery because of limb threatening ischemia (rest pain or gangrene). There was one early graft failure (successful thrombectomy). No patient died postoperatively. The mean follow-up period was 17.32 months (range 3-44 months). Cumulative patency rate for this follow-up period was 73%. Absence of kinking when bending the knee joint was determined by ankle Doppler pressure measurements and arteriography. If an adequate saphenous vein is not available for knee-crossing femoropopliteal bypass, externally supported PTFE can be used, yielding short-term patency rates comparable to those obtained with autologous venous bypasses.
27个外部支撑的聚四氟乙烯（PTFE）移植物被植入跨越膝关节的股腘位置。所有患者均因肢体威胁性缺血（静息痛或坏疽）接受手术。有1例早期移植物失败（成功进行了血栓切除术）。无患者术后死亡。平均随访期为17.32个月（范围3 - 44个月）。该随访期的累积通畅率为73%。通过踝部多普勒压力测量和动脉造影确定膝关节弯曲时有无扭结。如果没有足够的大隐静脉用于跨越膝关节的股腘旁路手术，可使用外部支撑的PTFE，其短期通畅率与自体静脉旁路手术相当。
