This retrospective study of 91 percutaneous transluminal angioplasties in 80 patients showed an overall patency rate by life-table analysis of 46 percent with a follow-up period of 36 months. Success rates were significantly reduced by predilatation ankle-brachial ratios less than 0.45, by diabetes, by pain at rest or necrosis, and somewhat, by older age. The overall success rate for iliac dilatation was significantly better (58 percent) than that in the femopopliteal segments (18 percent). Although percutaneous angioplasty was performed on many patients thought to be high surgical risks, the complication rate was low, and complications that required surgical intervention were rare (4 percent). Angioplasty was used as an adjunct to vascular surgery in several ways. An attempt to dilate a Dacron graft-femoral artery anastomosis was unsuccessful, and one of two dilatations distal to a femoropopliteal bypass was successful. However, the combination of an iliac angioplasty with outflow femoropopliteal or femorofemoral bypass produced a long-term patency rate of over 85 percent, significantly better than that achieved with iliac dilatation alone. Percutaneous transluminal angioplasty is both an alternative and an adjunct which should be considered by vascular surgeons for their patients.
这项对80例患者的91次经皮腔内血管成形术的回顾性研究显示，通过生命表分析，在36个月的随访期内，总体通畅率为46%。预扩张时踝肱指数低于0.45、患有糖尿病、有静息痛或坏死以及年龄较大等情况会使成功率显著降低。髂动脉扩张的总体成功率（58%）明显高于股腘动脉段（18%）。尽管对许多被认为手术风险高的患者进行了经皮血管成形术，但并发症发生率较低，需要手术干预的并发症很少（4%）。血管成形术在几个方面被用作血管外科手术的辅助手段。尝试扩张涤纶人工血管-股动脉吻合口未成功，股腘动脉旁路远端的两次扩张中有一次成功。然而，髂动脉血管成形术与流出道股腘动脉或股股动脉旁路联合应用产生的长期通畅率超过85%，明显优于单纯髂动脉扩张。经皮腔内血管成形术既是一种替代方法，也是一种辅助手段，血管外科医生应为其患者考虑采用。
