摘　　要：目的：本研究探讨64排CT对于冠状动脉完全闭塞病变介入治疗的指导意义。方法：单中心连续入选14例64排CT冠状动脉成像（CTA）和冠状动脉造影显示一支冠状动脉完全闭塞患者，介入处理病变14个。根据介入治疗是否开通病变分为2组。组间分析对比多排CT冠状动脉成像所示的斑块的性质、斑块的CT值。结果：介入失败组病变的CT分析显示4例是混合斑块、1例是钙化斑块。斑块的最大CT值为578～1278HU。介入成功组病变的CT分析显示2例是混合斑块、7例是软斑块。斑块的最大CT值为483HU。且支架释放后无残余狭窄。结论：本研究的结果提示，完全闭塞病变介入失败组病变多是混合、钙化斑块；与介入成功组比较，斑块的叮值明显较大。Objective：To explore the value of 64 slice CT coronary angiogrophy for percutaneous coronary intervention in coronary total occlusion lesion. Methods： 14 consecutive patients who undergone 64 slice CT coro- nary angiography and had one coronary artery total occlusion shown by coronary angiography were enrolled. 14 lesions were treated with percutaneous coronary intervention（PCI）. The patients were grouped into the opened group and the non- opened group according to the results of PCI. Lesion composition and CT value were com- pared between the two groups. Results： In the non - opened group there were four compound lesions and one cal- slum lesion, and the CT value was 578--1278 HU. In the opened group there were two compound lesions and seven soft lesions, and the maximal CT value was 483 HU. Conclusions： The study shows that, compared with the opened group, there are more compound and calsium lesions with overly large CT value in the non- opened group.
