摘　　要：35例冠脉造影患者行冠脉内超声成像检查（ICUS）。定性分析斑块成分、性质及夹层形成；测量冠脉最小管腔内径、面积、斑块面积及血管狭窄百分数等。冠脉造影结果10例正常，25例冠脉狭窄≥70％，其中17例行PTCA术。10例冠脉造影正常者中，5例ICUS有粥样硬化病变。17例左冠狭窄而左主干正常者中，ICUS示12例（70．6％）左主干有不同程度病变。另17例PTCA后，5例植入支架。对植入与未植入支架的ICUS定性和定量方面的特征进行比较。结论：ICUS可发现冠脉造影正常的冠脉病变。I－CUS为PTCA后的冠脉提供了理想的形态学资料，PTCA后残余狭窄＞50％，钙化偏心斑块或PTCA后有夹层者应植入支架。根据支架成功植入的超声诊断标准，ICUS可指导支架成功植入，避免急性血栓闭塞。Intracoronary ultrasound was performed in 35 patients undergoing coronary angiography and PTCA was performed in 17 patients among them. Morphologic characteristics of ICUS including plaque composition, topography and the presence of dissection were assessed. Quantitative measurements were obtained. Five among 17 patients undergoing angioplasty were implanted with stents after PTCA. The qualitative and quantitative measurements of ICUS images after angioplasty were compared between patients with stent implantation and stent nonimplantation. This study demonstrated that angiographically unrecognized atherosclerosis in coronary arteries including left main coronary artery can be found in ICUS images. ICUS provides satisfactory morphologic information of coronary after PTCA. When the residual percent area stenosis was more than 50% or dissection was assessed after PTCA or the plaque was eccentric and calcified characteristics, the stent should be implanted. ICUS is used to determine satisfied stent implantation, preventing from acute thrombosis ob
