动态三维超声彩流早期筛查胎儿心脏病的探讨

目的:探讨动态三维超声对胎儿心脏病早期诊断的价值。方法:随机对孕12～20周胎儿采用动态三维超声彩色复制模式,筛查心脏病,主要取四腔心、右室流出道与肺动脉长轴,左室流出道与升主动脉长轴等多切面检查。结果:433例孕12～20周胎儿筛查心脏病中,12例动态三维超声诊断胎儿心脏病,均行治疗性引产,10例病理尸解证实,其中1例心包积液,6例伴多发畸形。2例拒绝尸解。结论:动态三维超声对胎儿心脏病早期诊断具有重要价值。胎儿心脏动态三维超声血流显示更直观形象,有助胎儿心脏病早期诊断。

Application of real - time three - dimensional echocardiography in early fetal congenital heart diseases.

Objective:To explore the clinical application value of prenatal three-dimensional echocardiography for fetal congenital heart diseases.Methods:433 fetuses of pregnant women during 12~20 weeks gestation were randomly and routinely examined the fetal heart four-chamber,right ventricular outflow and pulmonary long axis,left ventricular outflow and aortic long axis view.Results:12 cases were found the fetal cardiovascular abnormality by real-time three-dimensional echocardiography and all were induced labor of these,nine cases were fetal CHD and one was pericardial effusion confirmed by autopsy,six cases were companied with other system multiple malformation other two cases were refused to autopsy.Conclusion:Real-time three-dimensional echocardiography has important clinical value for the screening and early diagnosis of prenatal CHD with its direct sonogram.
