A non-thermal Xenon-Chloride excimer laser was used for peripheral arterial recanalization in eight patients with obliterating atherosclerosis of the superficial femoral artery. All patients had a total occlusion with severe claudication or pain at rest. There were three complications, which all led to thrombosis of the irradiated artery. In one, the puncture site in the artery had to be closed operatively. All vessels were followed up radiographically three months after the procedure. In seven patients the vessel was patent. Several investigators have warranted caution in using thermal lasers (continuous wave Nd:YAG or argon) for angioplasty. The non-thermal excimer laser is a viable alternative--although not without problems. Initial experiences with the new device are described.
一台非热氯化氙准分子激光用于八名患有股浅动脉闭塞性动脉粥样硬化患者的外周动脉再通。所有患者均为完全闭塞，伴有严重间歇性跛行或静息痛。出现了三例并发症，均导致照射动脉血栓形成。其中一例，动脉穿刺部位必须通过手术闭合。术后三个月对所有血管进行了放射学随访。七名患者的血管保持通畅。几位研究者已提醒在使用热激光（连续波钕:钇铝石榴石或氩激光）进行血管成形术时要谨慎。非热准分子激光是一种可行的替代方法——尽管并非没有问题。本文描述了使用这种新设备的初步经验。
