摘　　要：目的　探讨超声观察卵圆孔瓣在胎儿房间隔缺损产前诊断中的临床意义。方法　应用彩色多普勒超声观察胎儿卵圆孔瓣结构 ,测定卵圆孔径 (A)与卵圆孔瓣顶点至卵圆孔中点距离 (B)的比值 ,将产前超声诊断与胎儿尸体解剖或分娩后超声检查结果对照。结果　产前超声诊断胎儿房间隔缺损 2 6例 ,9例产后尸体解剖证实 ;16例产后超声诊断为房间隔缺损 ,其中已手术证实 8例 ;1例假阳性。胎儿房间隔缺损的主要声像图特点是卵圆孔瓣消失或断裂 ,卵圆孔瓣增大且A/B <1。Objective To investigate the clinical significance of foramina ovale valve examined by echocardiography in the prenatal diagnosis of fetal atrial septal defect (ASD).Methods Interatrial septum and valve of foramina ovale of fetuses were visualized and measured by echocardiography for the prenatal diagnosis of fetal ASD.The prenatal echocardiographic diagnosis were confirmed by fetal outopsy or neonatal echocardiography as well as followup.Results Twentyfive cases of fetal ASD were confirmed in 26 cases of prenatal echocadiograohic diagnosis and one case is falsepositive.The imaging characterization of fetal ASD included disappearance or broken of foramina ovale vavle or enlargement of foramina ovale valve and the ratio of the diameter of foramina ovale to the distance of peak point of foramina ovale valve to the middle point of foramina ovale was less than 1.Conclusion Echocardiography visualizing the interatrial septum and valve of foramina ovale has important clinical value in the prenatal diagnosis of fetal ASD.
