近年来的研究证实,利用激光去除粥样硬化斑的激光血管成形术具有较好的治疗作用.在激光血管成形术的最初4例临床试验中,使用氩掺钕镱铝石榴石(Nd∶YAG)和CO_2激光都能成功地消除动脉的粥样硬化性阻塞.虽然初步效果满意,但远期效果及复发的危险还未明确,因此,还需要进一步研究.一、激光血管成形术的实验及应用研究1982年Choy等最先应用腔内激光血管成形术.在9个尸体心脏的15根冠状动 In recent years, studies have shown that laser laser atherectomy using laser angioplasty has a good therapeutic effect.In the first 4 cases of laser angioplasty clinical trial, the use of Nd Nd ytterbium doped garnet (Nd: YAG ) And CO_2 laser can successfully eliminate the arterial atherosclerotic occlusion.Although the initial results are satisfactory, but the long-term effect and the risk of recurrence is not yet clear, therefore, further study is needed.First, laser angioplasty experiments and Applied research Choy et al first used endovascular laser angioplasty in 1982.
