摘　　要：目的:评价多层螺旋CT在冠状动脉搭桥术后随访的临床应用价值。方法:选择2001-12/2005-04在东南大学医学院附属扬州医院行桥血管多层螺旋CT检查的冠状动脉搭桥术后患者12例,其中1例相隔1年后复查,共13次扫描检查资料。所有患者应用美国通用电气公司的十六排八层螺旋CT机,采用snapshot冠状动脉成像方法进行检测,并进行CT图像重建后处理,重建出各主要血管及桥血管。分析桥血管和冠状动脉的通畅性,评价狭窄及狭窄程度。结果:13例次患者的22支桥血管多层螺旋CT均能很好显示,其中17支桥血管开通,5支桥血管未开通(完全闭塞)或有不同程度狭窄。13例次患者原供血血管均可见不同程度管壁钙化、管腔狭窄或闭塞。结论:多层螺旋CT可以全面地显示心脏的结构与功能、心肌的血流灌注和存活状态,直接无创显示冠状动脉,对于冠状动脉桥血管开通和狭窄的评价具有很好的价值。AIM： To evaluate the clinical application value of multi-slice spiral CT （MSCT） in the postoperative follow-up of coronary artery bypass grafts. METHODS： Twelve patients, who accepted coronary artery bypass grafts in Yangzhou Hospital affiliated to the Medical College of Southeast University from December 2001 to April 2005, received examination with multi-slice spiral CT, and they were scanned with snapshot coronary artery imaging program （16-row detector 8-slice, GE Lightspeed MSCT）. One of them was reexamined after 1 year, and totally 12 scanning data were analyzed. The grafts and the patency were analyzed to evaluate the stenosis and its degree, RESULTS： MSCT could clearly display all the 22 grafts in the 13 cases and it indicated that 17 of the grafts were patent grafts and 5 with stenosis of different degrees （or even totally closed）. Of the 13 cases, there was calcification of dissepiment, chamber constriction or emphraxia to different degree. CONCLUSION： MSCT possesses the ability to display cardiac structure and its function, blood perfusion and the vitality of cardiac muscle. It can directly show coronary arteries non-traumatically, thus it is of good value in evaluating coronary artery patency and stenosis.
