血管内超声消融术 (intravascularultrasoundan gioplastyorablation)是近年来迅速发展的一种血管重建新方法 ,其主要原理是通过低频、高功率超声的机械振动、空化作用 (cavitation)等生物学效应裂解动脉硬化斑块和消融血栓 ,恢复闭塞血管的血液循环。 2 0世纪 6 0年代末美国Gr Intravascularultrasoundan gioplastyorablation is a rapidly developing new method of revascularization in recent years. Its main principle is to lyse atherosclerotic plaque by biological effects such as mechanical vibration and cavitation of low frequency and high power ultrasound Block and ablate thrombus and restore occlusion of blood vessels. 2 0 century the United States in the late 1960s Gr
