激光疏通周围血管的临床应用

Clinical application of laser channelizing peripheral arteries

我组于1984年开始进行了100条死体动物和人尸血管的基础实验,初步探索出激光疏通血管的方法、激光功率和发射时间等参数。接着进行了28条活体动物血管的激光疏通实验,成功率85％,1990年4月开始应用于临床,先后疏通了10条闭塞动脉。

Using Nd:YAG laser and optical fiber with a metal tip, 8 patients' 10 totally occluded peripheral arteries have been successfully channelized without hemorrhage and perforation occurred. The laser energy was from 360 J to 2808 J, and the length of channelized segments was from 6 cm to 45 cm. 7 patients had follow-up examination with Doppler velocimetry at one year. All of them didn' t have recurrence of symptoms.
