Direct laser light, in combination with percutaneous transluminal angioplasty (PTA), was used to recanalize atherosclerotic peripheral arteries. Argon laser energy was controlled with an optical assembly and aligned with a special centering/dilation balloon so that plaque tissue absorbed laser energy directly and was vaporized. A channel was thereby created with multiple 10-W laser exposures (2-10 seconds), and conventional angioplasty was then performed. Recanalization was achieved in 33 of 36 procedures (92%), in 23 femoropopliteal (mean length, 9 cm) and three iliac total occlusions and ten femoropopliteal high-grade stenoses, with the three failures occurring in the first group. Complications included two emboli, six moderate groin hematomas, and one laser perforation. While these results are preliminary (mean follow-up, 3 months), direct laser angioplasty appears to be a useful adjunct to PTA for treating atherosclerotic arteries.
直接激光与经皮腔内血管成形术（PTA）相结合，用于再通动脉粥样硬化性外周动脉。氩激光能量通过光学组件控制，并与特殊的定心/扩张球囊对齐，使斑块组织直接吸收激光能量并汽化。通过多次10瓦激光照射（2 - 10秒）形成一个通道，然后进行传统血管成形术。36例手术中有33例（92%）实现再通，其中23例为股腘动脉（平均长度9厘米）、3例髂总动脉完全闭塞以及10例股腘动脉高度狭窄，3例失败发生在第一组。并发症包括2例栓子、6例中度腹股沟血肿和1例激光穿孔。虽然这些结果是初步的（平均随访3个月），但直接激光血管成形术似乎是PTA治疗动脉粥样硬化动脉的有用辅助手段。
