通过光纤维传送的激光能量可用来使已闭塞的周围动脉再通,在治疗周围血管疾病时出现的后遗症上较外科动脉重建术为低。此外,动物研究以及Eugene等从使用人体激光动脉内膜切除术的研究提示,掌握动脉组织与激光能量的相互间作用可以限制激光动脉成形术后再狭窄。令人遗憾的是,现今激光成形设备仅能在闭塞动脉中造成小的通道以及激光能量仅作为球囊血管成形术的补充。这是因为激光在标测及血管显象上还存在些问题,以及现有激光系统还不能大量消融斑块以使直径达6～10mm,长20～40cm的闭塞血管再通。因此,现今利用激光能量来治疗周围血管疾病的可能性未能被
The laser energy delivered through the optical fiber can be used to recapture the occluded peripheral arteries and is less sequelae than surgical artery reconstructions in the treatment of peripheral vascular disease. In addition, animal studies and studies by Eugene et al. From human laser endarterectomy suggest that mastery of the interaction between arterial tissue and laser energy can limit restenosis after laser angioplasty. Unfortunately, today’s laser-forming devices are only able to create small channels in occluded arteries and laser energy is only used as a supplement to balloon angioplasty. This is because the laser in the mapping and vascular imaging there are still some problems, and the existing laser system can not massively ablate the plaque to make the diameter of 6 ~ 10mm, length of 20 ~ 40cm occlusion of recanalization. Therefore, the possibility of using laser energy to treat peripheral vascular diseases today can not be overcome
