超声心动图在胎儿单纯室间隔缺损产前诊断中的价值

目的探讨彩色多普勒超声心动图对胎儿单纯室间隔缺损产前诊断的价值。方法使用彩色多普勒超声诊断仪筛查胎儿心脏4898例,胎龄20～32周。在四腔心切面、左室长轴切面、右室流出道及肺动脉长轴等切面,观察室间隔有无回声中断及穿隔血流信号。结果产前超声共筛查诊断胎儿单纯室间隔缺损60例,合并21-三体综合征3例。结论彩色多普勒超声心动图能对胎儿绝大部分室间隔缺损做出产前诊断,对进一步诊断及治疗方案的选择有重要的临床价值。

Clinical Significance of Color Doppler Echocardiography in Diagnosis of Fetal Simple Ventricular Septal Defect

Objective To investigate the clinical significance of prenatal color Doppler echocardiography in fetal simple ventricular septal defect(VSD).Methods Totally 4 898 fetuses in 20-32 weeks were examined on color Doppler echocardiography on four-chamber views and multi-views,such as left ventricle long axis view,right ventricular outflow and pulmonary artery long axis views to determine VSD and color flow mapping was to detect shunt presence.Results Sixty fetuses with VSD were diagnosed on prenatal color Doppler echocardiography.Among them 3 cases were diagnosed 21-trisomy syndrome.Conclusions Color Doppler echocardiography can be employed to prenatally make diagnosis of simple VSD,to estimate prognosis and to choose rational therapy.
