摘　　要：目的比较16层螺旋CT和64层螺旋CT冠状动脉搭桥血管成像的效果。方法回顾性分析并比较了8例16层螺旋CT和19例64层螺旋CT冠状动脉搭桥术后患者的血管成像资料。结果64层螺旋CT对近端吻合口、搭桥血管本身、远端吻合口以及远端吻合口以远血管的可评价率分别为100%、100%、90.2%和93.9%,而16层螺旋CT则分别为92.3%、95.2%、90.0%和90.0%。64层螺旋CT评价近端吻合口、搭桥血管本身、远端吻合口以及远端吻合口以远血管的通畅率分别为66.7%、70.0%、71.7%和70.0%,而16层螺旋CT则分别为83.3%、85.0%、83.3%和88.9%。结论64层螺旋CT冠状动脉搭桥血管成像效果优于16层螺旋CT,可做为一种无创手段用于临床搭桥血管的术后随诊。Objective To compare the coronary artery bypass graft （CABG） imaging between 16-slice spiral CT and 64-slice spiral CT. Methods Totally 27 patients with CABG received multi-slice spiral CT imaging and the results were retrospectively analyzed. Among them, 8 patients received 16-slice spiral CT scanning, 19 patients received 64-slice spiral CT scanning. Results The evaluability rates of 64-slice spiral CT in evaluating the proximal anastomosis, bypass graft, distal anastomosis, and distal blood vessel were 100%, 100%, 90. 2%, and 93.9%, respectively, while those of 16-slice spiral CT were 92. 3%, 95. 2%, 90. 0%, and 90. 0%, respectively. The patency rates of the above four aspects of 64-slice spiral CT were 66. 7%, 70. 0%, 71.7%, and 70. 0% , respectively, while those of 16-slice spiral CT were 83.3%, 85.0%, 83.3%, and 88. 9% . Conclusions 64-slice spiral CT is superior to 16-slice spiral CT in CABG imaging. It can be used as a non-invasive tool for the post-operative follow-up of CABG.
