After the first intraoperative application of an Argon-laser by Choy in 1983, a special trial on laser angioplasty was started in Houston in 1985. Under the indications of tandem stenoses, diffuse atherosclerotic alteration or peripheral stenoses, laser endarterectomy was performed with a hand-held CO2-laser in addition to conventional bypass surgery. Between January 1985 and December 1986, 20 patients were treated with this combined method. Laser endarterectomy was successful in 37 out of 40 diseased vessels. After an interval of one week to 6 months after operation, 18 patients underwent a reangiography, showing a patency rate of 76% in the lased arterial segments. This result is comparable to conventional endarterectomy or intraoperative balloon angioplasty in similar cases. Further improvements can be expected by modifications in antiplatelet drug therapy.
1983年乔伊首次在手术中应用氩激光后，1985年在休斯顿开始了一项关于激光血管成形术的专项试验。在串联狭窄、弥漫性动脉粥样硬化改变或周围狭窄的适应症下，除了传统的搭桥手术外，还使用手持二氧化碳激光进行激光动脉内膜切除术。1985年1月至1986年12月期间，20例患者接受了这种联合治疗方法。40条病变血管中有37条激光动脉内膜切除术成功。术后间隔1周至6个月，18例患者接受了再次血管造影，显示激光治疗的动脉段通畅率为76%。这一结果与类似病例中的传统动脉内膜切除术或术中球囊血管成形术相当。通过抗血小板药物治疗的改进有望取得进一步进展。
