激光汽化血管内粥样硬化斑块时无法确保能量发放适当和组织损伤边界恰到好处,为其最大缺陷.据报告冠状动脉夹层分离和穿孔率为20%,围围动脉为25%.斑块消蚀面粗糙且再通血管内径较小,术后早、晚期均易再次闭塞.辐照灼热可致血管痉挛和剧痛,在周围血管此种情况的发生率为44%.最近作者以准分子激光(近紫外范围,308nm)汽化粥样斑块.镜检示切缘光整,基本无灼伤表现,
Laser vaporization of atherosclerotic plaque fails to ensure proper energy delivery and tissue damage at the right boundary, the largest of its defects. Coronary dissection and perforation were reported at 20% with 25% of the surrounding arteries. Rough surface and re-vascular diameter smaller, early and late are easy to occlusion again. Irration of burning can cause vasospasm and severe pain in the surrounding blood vessels in this case the incidence was 44%. Recent author with excimer laser (Near ultraviolet range, 308nm) vaporized atherosclerotic plaque. Mirror examination edge finishing, the basic non-burn performance,
