摘要
目的分析64排螺旋CT(MSCT)冠脉成像在冠状动脉搭桥(CABG)术后随访中临床应用价值。方法回顾性分析2015年1月到2017年3月在本院进行CABG治疗患者56例,搭桥共127支。对患者所得图像进行分析,并以CAG检查为基准,了解MDCT冠脉成像在冠状动脉搭桥术后随访中狭窄情况诊断价值以及不同桥血管通畅情况。结果在术后2年随访,56例患者127支桥血管情况通畅为81.10%(103/127),狭窄11.02%(14/127),闭塞7.87%(10/127);以CAG检查为“金标准”,MSCT检查敏感性为91.30%(21/23),特异性为94.23%(98/104),阳性预测值80.86%(21/26),阴性预测值97.02%(98/101)准确度93.70%(119/127)。结论MSCT为无创检查且检查费用低,CT冠脉成像在CABG术后随访中临床应用价值高,值得临床推广。
Objective To analyze the clinical application value of 64-slice spiral CT(MSCT)coronary imaging in the postoperative follow-up of coronary artery bypass graft(CABG).Methods The data of 56 patients who underwent CABG treatment in our hospital from January 2015 to March 2017 were retrospectively analyzed.There were 127 bridging.The images of the patients were analyzed,and the CAG examination was used as a benchmark to understand the diagnostic value of MDCT coronary angiography for stenosis and graft patency in the postoperative follow-up of coronary artery bypass graft.Results After 2 years of follow-up,the graft patency of 127 bridge vessels in 56 patients was 81.10%(103/127),stenosis rate was 11.02%(14/127),and occlusion rate was 7.87%(10/127).The CAG was used as the gold standard.The sensitivity of the MSCT was 91.30%(21/23),the specificity was 94.23%(98/104),the positive predictive value was 80.86%(21/26),and the negative predictive value was 97.02%(98/101),and accuracy was 93.70%(119/127).Conclusion MSCT is a non-invasive examination with low examination costs.CT coronary imaging is of high clinical value in the follow-up of CABG surgery and it is worthy of clinical promotion.
