超声心动图产前诊断胎儿心血管畸形的临床分析

THE CLINICAL ANALYSIS OF ECHOCARDIOGRAPHIC ANTENATAL DIAGNOSIS OF CARDIOVASCULAR MALFORMATION IN FETUS

为了在产前能够诊断胎儿心血管发育异常，评估其超声诊断价值，我们联合应用Ｍ型及二维超声心动图对孕１６周以上的孕妇３１０例进行产前检查，其检出先天性心脏病胎儿１１例，经引产尸解及生后随访证实。并发现从有高危因素的孕妇中检出率（５．５％）明显高于无高危因素的孕妇（０．７％），两组检出率有显著差异（Ｐ＜０．０５）。本文认为对具有高危因素的孕妇产前应用超声心动图检查胎儿心脏，诊断胎儿心血管发育异常有重要的实用价值。

In order to diagnose cardiovascular malformation in fetus and evaluate the importance of echographic diognosis,M-mode, Two-dimensionalmode and Pulsed Doppler Echocardiography were used in combined manner for examining the 310 fetuses after 16 weeks of gestation. 11 cases of cardiovascular malformation have been detected. All cases with the malformation were confirmed at autopsy or interview after delivery. The detected rate was significantly higher in high-risk pregnancies(5.5%)than that in non-hish-risk pregnancies (0.7%).There was a significant difference between the two groups in the detected rate(P<0.05).This study showed that echocardiographic diagnosis was useful for cardiovascular malfarmation in fetus with high maternal risk factors.
