目的:利用循证医学方法,对双源CT评价冠状动脉搭桥术(CABG)后桥血管狭窄程度的价值进行Meta分析。方法:检索CNKI、万方、维普数据库以及Cochrance Library、Pub Med、OVID、Embase等外文数据库,搜索双源CT诊断桥血管狭窄程度的诊断性试验。对纳入资料使用Meta-disc 1.4软件进行分析计算,计算合并敏感度、特异度和诊断比值比。结果:最终入选5篇文献,其合并敏感度、特异度和诊断比值比分别为99%、99%、4 984,受试者工作特征曲线下面积为99.84%。结论:双源CT对于CABG后桥血管的评价具有很高的诊断效能和临床意义。
OBJECTIVE: To evaluate Meta-analysis of the value of dual-source CT in assessing the degree of stenosis of posterior coronary artery bypass graft (CABG) using evidence-based medicine. Methods: The diagnostic tests for the diagnosis of stenosis of the bridge by dual-source computed tomography were searched for CNKI, Wanfang, VIP databases and Cochrane Library, Pub Med, OVID, Embase and other foreign databases. The included data were analyzed using the Meta-disc 1.4 software to calculate the combined sensitivity, specificity, and diagnostic odds ratio. Results: The final five selected articles were 99%, 99% and 4 984, respectively. The area under the receiver operating characteristic curve was 99.84%. Conclusion: Dual-source computed tomography (CT) has high diagnostic efficacy and clinical significance for the evaluation of posterior vascular of CABG.
