Unilateral iliac femoral reconstructions with PTFE are yielding good results-similar to those with Dacron, with patency rates of 75, 67, and 65% at 1, 2 and 3 years, respectively (Kaplan-Meier). PTFE has additional advantages compared with other materials: a) no need of preclotting; b) smooth inner surface-easy thrombectomy in case of thrombosis and c) good handling characteristics. In view of the above-mentioned facts PTFE can be recommended without restriction for unilateral pelvic reconstructions. The functional early results of bilateral aorto-femoral Goretex-Y bifurcation grafts in 50 cases after 2 years are encouraging. Long-term results are still pending. Reports of other groups using this material as aorto-bifemoral substitute are not yet available. The functional results with PTFE for femoro-popliteal grafts are not satisfactory: 35% after 2.5 years. Extra-anatomical bypasses yielded 70% one-year functioning rate. Especially the ring-or spiral-armoured PTFE grafts seem to be suitable for these reconstruction procedures.
采用聚四氟乙烯（PTFE）进行单侧髂股血管重建取得了良好效果，与采用涤纶的效果相似，1年、2年和3年的通畅率分别为75%、67%和65%（Kaplan-Meier法）。与其他材料相比，PTFE具有额外优势：a）无需预凝；b）内表面光滑，血栓形成时易于取栓；c）操作性能良好。鉴于上述情况，PTFE可无限制地推荐用于单侧盆腔重建。50例双侧主动脉-股动脉Goretex-Y型分叉移植物术后2年的早期功能结果令人鼓舞。长期结果仍有待观察。其他组使用该材料作为主动脉-双股动脉替代物的报告尚未可得。PTFE用于股腘动脉移植物的功能结果并不令人满意：2.5年后通畅率为35%。解剖外旁路移植的1年功能率为70%。特别是环形或螺旋增强型PTFE移植物似乎适用于这些重建手术。
