目的 探讨产前超声在诊断胎儿心脏畸形中的应用价值.方法 回顾性分析该院自2009年开展胎儿系统筛查以来查出的59例胎儿心脏先天性异常的声像图表现孕晚期并总结分析4例漏诊的原因.结果 44例胎儿心脏先天性异常于20~28周筛查时查出,占胎儿心脏异常总数的74.6%;孕晚期查出15例,占25.4%,其中2例室间隔缺损孕晚期复查已愈合,漏诊4例于出生后经超声心动图确诊.结论 产前超声可提高胎儿心脏异常的检出率,对产前诊断胎儿心脏畸形有重要意义.%Objective To evaluate the value of prenatal ultrasound in the diagnosis of fetal cardiac malformations. Methods We retrospectively analyze the ultrasonographic results of the identified 59 cases of congenital fetal heart abnormalities in the fetal systematic screening carried out in our hospital since 2009, and summarized the reasons for the 4 missed diagnosis cases. Results 44 cases of congenital fetal heart abnormalities were detected during 20~28 weeks old,accounting for 74. 6% of the total number, 15 cases were identified during late pregnancy,accounting for 25. 4%,in which 2 cases of ventricular septal defect were healed in the third trimester review. The missed 4 cases were diagnosed by echocardiography after birth. Conclusion Multi-slice sectional scanning based on four-chambered heart and two-bedroom outflow tract section,together with color Doppler can improve the detecting rate of fetal cardiac anomalies, which is important for prenatal diagnosis of fetal cardiac malformations.
