摘要目的 探讨超声心动图对复杂胎儿先天性心脏畸形的评价及临床意义.方法 对产前超声检查发现的复杂胎儿先天性心脏畸形声像图特征行产后尸解和病理验证.结果 超声心动图产前诊断复杂胎儿先天性心脏畸形20例.各类畸形包括:单心室4例,大动脉转位2例,右室双出口2例,永存动脉干2例,左心发育不良综合征3例,心内膜垫缺损3例,右心室发育不良2例,法洛四联症1例,肺动脉闭锁1例.超声产前诊断率100%.结论 超声心动图可以对复杂胎儿先天性心脏畸形进行综合评价,对帮助临床采取相应的决策和产前孕妇及家属知情具有重要意义.

abstractsObjective To discuss the value of pregnantal ultrasonography(US) on fetus' complicate congenital heart diseases(CHD). Methods The uhrasonographic fetures of fetus complicate CHD were analyzed and compared with the pathological diagnosis. Resells Twenty fetus' complicate CHD were diagnosed by pregnantal US. Four cases with single ventricle, two eases with transposition of great arteries,two eases with double outlet right ventricle,two cases with truncus arteriosus,three cases with hypoplastic left heart syndrome, three cases with endocardial cushion defect, two cases with hypoplastic right heart syndrome,one case with tetralogy of Fallot and one case with pulmonary atresia were included. The diagnosing according rate was 100%. Conclusions Pregnantal US can fully evaluate the fetus' complicate CHD.
