摘　　要：目的:探讨血管内超声显像(IVUS)检测对冠状动脉粥样硬化斑块病变性质的诊断价值及其在指导介入性治疗中的作用。方法:采用IVUS检测100例冠状动脉粥样硬化性心脏病(冠心病)患者124处冠状动脉血管段总截面积及其平均径、血管腔面积及其平均径,计算直径狭窄率及面积狭窄率,了解粥样硬化斑块的组成、分布及特性,并与同时进行的冠状动脉造影结果相比较。结果:IVUS检测发现偏心性斑块92处,向心性斑块32处,其中96处为严重冠状动脉病变节段,需要进行冠状动脉的介入性治疗或冠状动脉旁路移植术。冠状动脉造影(CAG)对于狭窄血管的直径及直径狭窄率的测值较低,IVUS测值与其比较有显著的统计学意义。结论:IVUS对于冠状动脉粥样硬化斑块病变性质的检测明显优于冠状动脉造影,对冠状动脉介入手术的选择方案有着指导意义。Objective:To evaluate intravascular ultrasou nd(IVUS)in the diagnosis and interventional treatment of coronary atherosclerotic plaque.Methods :Total vessel area(TVA),average diameters of total vessel,lumen area(LA)and average diame-ters of lumen were measured in 124coronary artery segments by IVUS.The di ameter stenostic rate(DSR)and area stenostic rate(ASR)were calculated.The composition,distribution and characteristics o f plaque were also studied.Results w ere compared to coronary angiography(CAG).Results:92eccentric and 32concentric plaques were found,96of which were severe and required intervention or coronary artery by-pass.The diameter was smaller and DSR was lower by CAG than those measured by IVUS.There were significant differences betwe en CAG and IVUS.Conclusions :IVUS is superior to CAG for studying c haracteristics of coronary atherosclerotic plaque.IVUS is more important than CAG in selecting ind ications of coronary artery interve ntional operation.[
