摘　　要：目的:评价多层螺旋CT在冠状动脉搭桥术后随访的价值。方法:32例冠状动脉成像病例中有3例冠状动脉搭桥术后病人（共有搭桥血管7根）。分析搭桥血管及冠状动脉通畅性,评价狭窄及狭窄程度。结果:7根搭桥血管都在VR、MPR及Curved上很好地显示,其中有1根可见约75％～90％之狭窄;其余均通畅。结论:多层螺旋CT对冠状动脉搭桥术后随访有很高的价值。Objective: To evaluate multi-slice spiral CT(MSCT) in the follow-up of coronary artery bypass grafts (CABG). Methods:Of the 32 cases of MSCT coronary artery imaging,there were three CABG (with seven bypass grafts). The patency of the bypass grafts was analyzed to evaluate the degree of bypass grafts stenosis. Results: The seven bypass grafts were clearly displayed on VRNMPR and Curved images. One bypass graft has a 75%-90% stenosis,the others were patent. Conclusion: MSCT has great potential value in the follow-up of CABG.
