Fifty patients undergoing 51 percutaneous transluminal angioplasties of the femoropopliteal segment for severe limb ischaemia were reviewed regularly. They comprised 30 men and 20 women of median age 70 (range 56-85) years. There were two deaths within 30 days. At 2 years the cumulative patient survival rate was 60 per cent. Eleven angioplasties were technical failures, 25 failed in the first 6 months and 14 were successful at 6 months' follow-up; in addition one patient died from myocardial infarction within 30 days of technically successful angioplasty. Subsequent vascular procedures were successful in 11 limbs following failed angioplasty. The primary limb survival rate was 42 per cent at 2 years. There were eight major complications after angioplasty, requiring amputation in five instances. Of the 23 long occlusions (greater than 5 cm) that were recanalized and dilated, 22 procedures failed within 6 months. The run-off score and diabetic status did not predict outcome. In this group of patients angioplasty had a low durability. Dilatation of long occlusions is associated with high rates of reocclusion and, on the basis of these results, should not be performed.
对50例因严重肢体缺血接受51次股腘段经皮腔内血管成形术的患者进行了定期随访。他们包括30名男性和20名女性，年龄中位数为70岁（范围56 - 85岁）。30天内有2例死亡。2年时患者累积生存率为60%。11次血管成形术技术失败，25次在最初6个月内失败，14次在6个月随访时成功；此外，1例患者在血管成形术技术成功后30天内死于心肌梗死。血管成形术失败后，后续血管手术在11条肢体上取得成功。2年时主要肢体生存率为42%。血管成形术后有8例主要并发症，5例需要截肢。在23例再通并扩张的长闭塞（大于5 cm）中，22例手术在6个月内失败。流出道评分和糖尿病状态不能预测预后。在这组患者中，血管成形术的耐久性较低。长闭塞的扩张与再闭塞率高相关，基于这些结果，不应进行。
