超声心脏轴测定在筛查胎儿先天性心脏病中的临床意义

The Clinical Significance of Ultrasonography in Screening Fetal Congenital Heart Disease

目的探讨超声心脏轴测定在筛查胎儿先天性心脏病中的价值。方法收集产前检查的孕18周以上高危先心病胎儿孕妇550例,均进行产前心脏超声四腔观与联合心脏轴测定,比较单纯心脏超声四腔观与联合心脏轴测定对胎儿先心病的诊断准确性。结果产前心脏超声四腔观联合心脏轴测定结果中,正常胎儿心轴左偏率、心轴右偏均低于先心病胎儿(P<0.05)。产前心脏超声四腔观联合心脏轴测定的诊断准确率高于单纯心脏超声四腔观(P<0.05)。结论单纯心脏超声四腔观结合心脏轴测定能提高产前超声检查的准确率,可作为四腔观的一个辅助指标。

Objective To investigate the value of echocardiography in the diagnosis of fetal congenital heart disease.Methods Collected prenatal examination of pregnant over 18 weeks, the risk of pregnant women fetal congenital heart disease 550 cases were prenatal ultrasound cardiac four chamber view and combined cardiac axis determination, relatively simple cardiac four chamber view and combined cardiac axis determination of fetal heart disease diagnosis accuracy.Results Prenatal ultrasound heart four chamber view with cardiac axis determination results, normal fetuses of the left axis deviation rate, right axis partial were lower than CHD fetuses （P〈0.05）. The diagnostic accuracy of prenatal echocardiography combined with cardiac axis measurement was higher than that in the four cavity view （P〈0.05）.Conclusion The combination of simple cardiac ultrasound and four chamber view can improve the accuracy of prenatal ultrasound examination, so it can be used as a supplementary index of the four views.
