【摘要】 目的探讨三维超声产前诊断胎儿畸形的临床应用价值。方法对2003年1月至2006年12月应用三维超声进行产前检查发现的29例24～40周胎儿畸形超声影像与临床资料进行回顾性分析。结果唇裂11例、无脑儿7例、四肢短小4例、脐膨出3例、颈部淋巴囊肿3例、羊膜带综合征1例，与临床产出胎儿所见畸形特征完全一致。结论三维超声对胎儿畸形的检出率高，是有效的产前筛查方法。

The antepartum diagnosis value of fetal anomaly by threedimensional ultrasonography
Abstract: Objective To investigate the clinical value of threedimensional ultrasonography in screening fetal abnormality before birth. Methods The present paper retrospectively analyzed the threedimensiona ultrasonography data of 29 cases fetal anomaly between 24 and 40 weeks’ gestation from Jan 2003 to Dec 2006. Results Among them, there were 11 cases of cheilognathus,7 cases of anencephalus, 4 cases of anomaly of extremities, 3 cases of omphalocele, 3 cases of lymphocyst at the neck and 1 case of amniotic band syndrome. The anomaly features are consistent with those of the born fetuses. Conclusion The threedimensional ultrasonography increases the accurate rate of diagnosing fetal anomaly and is an effective prenatal screeing method.
