双源CT对冠脉搭桥术后桥血管评价的Meta分析

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、PubMed、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-disc1.4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%、4984,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。 

Meta Analysis on Graft Vessels Evaluation after Coronary Artery Bypass Grafting by Dual Source CT

Objective:To use the method of evidence-based medicine,Meta analysis of bridge stenosis value evaluation of dual source CT coronary artery bypass surgery.Methods:Retrieval of foreign language databases of CNKI,Wanfang,VIP database and the Cochrane Library,PubMed,Ovid,Embase etc,the search of dual source CT in the diagnosis of graft stenosis diagnostic test.Use Meta-disc 1.4 software to analyze and calculate the data,and calculate the sensitivity,specificity and diagnostic odds ratio.Results:5 papers were selected,and their combined sensitivity,specificity and diagnostic odds ratio were 99％,99％ and 4 984,respectively.The area under the receiver operating characteristic curve was 99.84％.Conclusion:Dual source CT has clinical significance in diagnosis and high efficiency for the evaluation of bridge vessels after CABG.
