为评价激光血管成形术的效果和安全性,四所教学医院对338例硬化性股腘动脉闭塞病人进行了前瞻性研究。研究对象为股腘动脉闭塞2cm以上和闭塞时间至少4个月者。研究中不包括髂动脉及股浅动脉起始端闭塞或急性血栓形成或栓子性闭塞病人,也不包括不能长期服用乙酰水杨酸和潘生丁或抗维生素K药物的病人。男242例,女96例,年龄30～91岁。股腘动脉闭塞长度2～26cm(平均8.5cm),闭塞期4～36月(平均13月)。227例进行性跛行,56例休息时疼痛,55例有坏疽。四个中心所用技术相同,全部病例使用钕钇铝石榴石(NdYAG)激光,波长1064nm,用蓝宝石接触探头,
To evaluate the efficacy and safety of laser angioplasty, 338 338 patients with sclerosing femoral artery occlusion were prospectively studied in four teaching hospitals. The subjects were over 2 cm in occlusion of femoral artery and occlusion for at least 4 months. Excluding the initial occlusion of the iliac artery and superficial femoral artery or acute thrombosis or embolic occlusion in patients not included in the study, patients who did not take acetylsalicylic acid and dipyridamole or anti-vitamin K drugs for extended periods of time were excluded. 242 males and 96 females, aged 30 to 91 years. The length of femoral artery occlusion was 2 ~ 26cm (mean 8.5cm) and occlusion period was 4 ~ 36 months (average 13 months). 227 cases of progressive claudication, 56 cases of rest pain, 55 cases of gangrene. The techniques used in the four centers were the same, with neodymium-yttrium aluminum garnet (NdYAG) laser in all cases at a wavelength of 1064 nm, sapphire contact probes,
