摘　　要：目的采用64层CT血管成像评价糖尿病患者冠状动脉旁路移植(CABG)术后桥血管病变的特征。方法收集39例冠状动脉CABG术后患者,其中临床确诊糖尿病患者20例,无糖尿病患者19例。应用64层螺旋CT行冠状动脉CTA检查,由两位有经验的医生来评估分析近期桥血管是否通畅、有无斑块及斑块性质进行分析。结果二组桥血管病变中,糖尿病患者的斑块检出率明显高于无糖尿病患者组(P<0.05),糖尿病组重度狭窄病变明显多于非糖尿病组(P<0.05)。前者以弥漫性钙化或混合斑块为主,管腔呈中、重度狭窄。后者以少量非钙化斑块为主,管腔以轻中、度狭窄为主,二组差异有统计学意义(P<0.05)。结论糖尿病患者旁路移植(CABG)术后桥血管有高度的冠状动脉病变危险性,糖尿病患者并发桥血管病变较非糖尿病患者严重,且以钙化或混合斑块为主。CTA可清晰显示冠状动脉桥血管图像,对临床评估冠心病风险具有重要价值。Objective To anaiysis the characteristics of vascular lesions of coronary artery bridge of patients with diabetes coronary artery bypass graft （CABG） surgery with 64 CT. Methods The data of 39 patients with coronary artery CABG surgery were selected, which including 20 patients with clinically diagnosed di- abetes, and 19 cases patients without diabetes. And then coronary artery was checked with layer 64 line spiral CT, vascular patency was assessed by two experienced doctors, the imaging properties were analyzed if there was any plaques, and bridge plaque distribution. Results CTA image for all patients were clearly, and it could display the bridge vascular patency, stenosis or occlusion. Vascular lesions in the two groups of bridge, patches of diabetes patients was significantly higher than the patients without diabetes group （P〈0.05）. The former was given priority to with calcification or mixed plaques, the latter was given priori- ty to with a small amount of soft plaques, no statistical difference between the two groups （P〈0.05）. Conclusions The patients have Bypass graft （CABG） surgery with diabetes vascular Bridges show high risk of coronary artery pathological changes. Diabetic patients complicated with bridge vascular lesions compared with non- diabetic patients were severe, and given priority to with calcification or mixed plaques. CTA can display coronary artery bridge vascular images with the important value to assess coro- nary heart disease risk in clinic.
