摘　　要：目的通过应用冠状动脉16层螺旋CT(MSCTA)成像对冠脉搭桥手术后桥血管评价,研究其临床应用的可行性。方法2年共观察53例冠脉搭桥手术患者,术前常规冠脉造影检查,手术行不停跳冠脉搭桥术,手术后3个月、1年分别行冠状动脉16层MSCTA,其中17例患者在术后1年冠状动脉16层MSCTA复查后于1周内行冠脉造影检查。结果冠状动脉16层MSCTA能够成功显示冠脉搭桥手术后桥血管状况比例分别为术后3个月99.36%,术后1年98.72%。对冠脉搭桥手术后桥血管评价,冠状动脉16层MSCTA与冠脉造影结果进行对比,其敏感度达到100%。结论应用冠状动脉16层MSCTA对冠脉搭桥手术后桥血管评价简便、无创、可信可行。Objective To evaluate the clinical application of 16-slice spiral computed tomography angiography （MSCTA） in patients with coronary artery bypass grafis（CABG）. Methods 53 patients after CABG accepted MSCTA, in which MSCTA of 17 patients was compared with quantitative coronary angiography which servedas the golden standard. Results One year after CABG, 98.72% of bypass grafts of 53 patients were assessable, in which 17 segments of bypass grafts were unobstructed. 9 segments were obstructed confirmed by quantitative coronary angiography （sensitivity 100%）. Conclusion The multi-spiral computed tomography angiography of coronary arteryis a simple, reliable, noninvasive, comfortable and no-expensive way for CABG and has a pmfoundclinical apphcation value.
