Percutaneous transluminal laser angioplasties (PTLA) were performed in nine patients (7 males, 2 females, aged 52-81 years) with peripheral vascular disease, stages IIB-IV (Fontaine's classification), with 75% stenosis (5 patients) or occlusion (4 patients) in the area of the superficial femoral artery. Two catheter systems were used. One was a monofiber catheter (600 microns) with eccentric guidewire, the other a multifiber catheter with 12 concentrically arranged fibres (200 microns each) and a central guidewire. An XeCl-excimer laser (308 nm), with a pulse duration of 50 ns and pulse frequency of 15-30 Hz, served as the laser source. It was possible in all patients to reduce the stenosis of 75-100% to 35-70% or reopen the occlusion without laser-associated complications. To remove the residual stenosis PTLA was followed by balloon dilatation in seven patients and by application of a Simpson atherectomy catheter in one patient: these measures reduced the degree of stenosis to 20-40%.
对9例（7例男性，2例女性，年龄52 - 81岁）患有外周血管疾病、处于IIB - IV期（Fontaine分类法）的患者进行了经皮腔内激光血管成形术（PTLA），这些患者的股浅动脉区域存在75%的狭窄（5例）或闭塞（4例）。使用了两种导管系统。一种是带有偏心导丝的单纤维导管（600微米），另一种是带有12根同心排列纤维（每根200微米）和中心导丝的多纤维导管。一台XeCl准分子激光器（308纳米），脉冲持续时间为50纳秒，脉冲频率为15 - 30赫兹，用作激光源。所有患者都有可能将75% - 100%的狭窄程度降低到35% - 70%，或重新开通闭塞处，且未出现与激光相关的并发症。为消除残余狭窄，7例患者在PTLA后进行了球囊扩张，1例患者应用了Simpson旋切导管：这些措施将狭窄程度降低到了20% - 40%。
