主动脉缩窄(coarctation of the aorta,CoA)的产前诊断仍然具有挑战性,并受高频率的假阳性诊断的影响。该项研究的目的是确定相关性强度,并量化不同超声显像数据在预测产前CoA的诊断准确性。方法:检索Medline,Embase,Cinahl和Cochrane数据库,进行系统评价和荟萃分析。结果:共检索文章794篇,其中12篇(922名具有CoA风险的胎儿)纳入分 Prenatal diagnosis of coarctation of the aorta (CoA) is still challenging and is affected by the high frequency of false positive diagnoses. The purpose of this study was to determine the strength of the correlation and to quantify the diagnostic accuracy of different ultrasound imaging data in predicting prenatal CoA. METHODS: Medline, Embase, Cinahl, and Cochrane databases were searched for systematic reviews and meta-analyzes. RESULTS: A total of 794 articles were retrieved, of which 12 (922 fetuses with CoA risk) were included in the study
