We aimed to analyze the echocardiographic characteristics and pregnancy outcomes for fetuses with premature complete closure of the fetal ductus arteriosus.
A retrospective analysis was performed for eight cases of premature ductus arteriosus closure diagnosed by prenatal ultrasonography in the Hunan Maternal and Child Health Hospital from July 2019 to August 2022, and the characteristics of fetal echocardiography and pregnancy outcomes of the eight cases were analyzed and summarized.
In all cases, the intima of the ductus arteriosus was thickened and occluded, the ductus arteriosus could be seen with slightly hyperechogenic, and no blood flow signal was found in the ductus arteriosus by Doppler ultrasonography. The right heart was enlarged in seven cases, and the whole heart was enlarged in one case. Tricuspid valve regurgitation was observed to different degrees, of which seven cases were severe and one case was moderate. The pulmonary arteries of eight patients had varying degrees of widening. All eight cases were delivered by cesarean section, and one newborn died after follow-up. The prognosis of the other newborns was good.
The parameters of prenatal echocardiography are helpful for the prognosis of fetuses with premature closure of the ductus arteriosus. Early prenatal detection, close observation, and clinical guidance can be used to select the right time of delivery.
分析胎儿动脉导管过早完全闭合的超声心动图特征及妊娠结局。
回顾性分析 2019 年 7 月至 2022 年 8 月湖南省妇幼保健院经产前超声诊断为动脉导管过早闭合的 8 例病例，分析总结 8 例胎儿的超声心动图特征及妊娠结局。
8 例均表现为动脉导管内膜增厚、管腔完全闭锁，多普勒超声未见血流信号，动脉导管呈稍高回声，其中 7 例右心增大，1 例全心增大，均可见不同程度三尖瓣反流，其中 7 例重度，1 例中度。8 例肺动脉均不同程度增宽。8 例均经剖宫产分娩，1 例新生儿死亡，其余新生儿预后良好。
产前超声心动图参数有助于预测胎儿动脉导管过早闭合的预后。早期产前发现、密切观察、临床指导有助于选择合适的分娩时机。
