Limb-salvage was the indication for 90% of 206 attempted PTAs in 175 patients between 1976 and 1982. Life-table patency rates at 4 years for the angiographically successful iliac PTA and femoropopliteal PTA were 78% and 50%, respectively. PTA of eight iliac, seven femoropopliteal, nine tibial, and two subclavian arteries and one autogenous saphenous vein graft (ASV) were unsuccessful. Of these, 17 subsequently underwent successful bypass grafts and five required below-knee amputations. Ten iliac, 37 femoropopliteal, four tibial, and two ASV graft PTAs failed. Of 20 repeat attempts at PTA, only two have achieved long-term patency. Appropriate surgery allowed limb salvage in 23 of 36 early failures (less than 3 months) and 12 of 14 late failures (greater than 3 months), and usually consisted of the same operation that would have been performed had PTA not been attempted. Fifty-two complications were classified according to the method of treatment. Fourteen warranted surgery, but in 10 this was successfully achieved by the same operation that would have been required had PTA not been performed.
1976年至1982年间，175例患者进行了206次经皮腔内血管成形术（PTA）尝试，其中90%的目的是保肢。经血管造影成功的髂动脉PTA和股腘动脉PTA的4年生命表通畅率分别为78%和50%。8例髂动脉、7例股腘动脉、9例胫动脉和2例锁骨下动脉的PTA以及1例自体大隐静脉移植（ASV）未成功。其中，17例随后成功进行了旁路移植术，5例需要进行膝下截肢。10例髂动脉、37例股腘动脉、4例胫动脉和2例ASV移植的PTA失败。在20次PTA重复尝试中，只有2例实现了长期通畅。适当的手术使36例早期失败（少于3个月）中的23例和14例晚期失败（大于3个月）中的12例得以保肢，手术通常与未尝试PTA时本应进行的手术相同。根据治疗方法对52例并发症进行了分类。14例需要手术，但其中10例通过与未进行PTA时所需相同的手术成功完成。
