Recanalization of 75 femoropopliteal arterial occlusions was attempted with either conventional percutaneous transluminal angioplasty (n = 28; mean occlusion length, 5.5 cm) or percutaneous laser-assisted angioplasty (PLA) (n = 47; mean occlusion length, 11.6 cm). Conventional recanalization was technically successful in 21 patients (mean occlusion length, 4.4 cm +/- 3.9) and was a technical failure in seven (mean occlusion length, 8.7 cm +/- 6.2). The technical outcome was a function of the length of the occlusion (P = .04). The PLA procedure, performed with a laser with a sapphire probe, was a technical success in 32 patients (mean length, 10.7 cm +/- 6.5) and a technical failure in 15 (mean length, 13.6 cm +/- 8.2). With PLA, the length of the occlusion did not determine the technical (P = .20) or clinical (P = .12) outcome. In patients with gangrene, PLA of occlusions longer than 5 cm failed clinically (P = .02). This PLA method appeared to be safe and allowed passage through occlusions longer than 10 cm.
对75例股腘动脉闭塞尝试进行再通，其中采用传统经皮腔内血管成形术（n = 28；平均闭塞长度5.5 cm）或经皮激光辅助血管成形术（PLA）（n = 47；平均闭塞长度11.6 cm）。传统再通术在21例患者中技术成功（平均闭塞长度4.4 cm±3.9），7例技术失败（平均闭塞长度8.7 cm±6.2）。技术结果是闭塞长度的函数（P = 0.04）。使用蓝宝石探头激光进行的PLA手术，32例技术成功（平均长度10.7 cm±6.5），15例技术失败（平均长度13.6 cm±8.2）。对于PLA，闭塞长度并不决定技术（P = 0.20）或临床（P = 0.12）结果。在患有坏疽的患者中，长度超过5 cm的闭塞的PLA临床失败（P = 0.02）。这种PLA方法似乎是安全的，并且能够通过超过10 cm的闭塞。
