摘　　要：目的通过临床病例探究超声心动图对晚孕期胎儿动脉导管(DA)早闭及狭窄的诊断及影像特征。方法选取经产后确诊的8例DA早闭及狭窄的胎儿超声心动图资料进行回顾性分析。结果 7例胎儿超声心动图未显示DA及血流信号,1例DA狭窄,同时均表现为右心室压力负荷过重,三尖瓣均有轻中度以上反流。患儿在出生后24h内复查超声心动图结果:7例患儿未探及DA及血流信号,1例仍残留DA,所有患儿右心室压力均有好转。3个月后再次进行超声心动图复查结果:残留DA消失,所有患儿心脏结构及功能均恢复正常。结论结合三尖瓣反流及右心室压力负荷过重的超声心动图表现对及早发现胎儿DA早闭及狭窄具有重要的参考价值。Objective To explore the echocardiographic diagnosis and imaging features of prenatal closure and stenosis of the fetal ductus arteriosus（DA） during late pregnancy by analysis of clinical cases. Methods Eight cases of prenatal closure and stenosis of the fetal DA were examined by echocardiography and confirmed postnatally. The echo- eardiographic characteristics were reviewed and analyzed,The diagnosis idea was summarized. Results All of the 7 ca ses of prenatal closure of the fetal DA did not show DA and blood flow signal in echocardiogram. One case whose DA was stenosis. At the same time, right ventricular pressure overload. Tricuspid valve regurgitations were mild to mod- erate or more serious. The results of echocardiography in 24 h after birth were reviewed. DA and Mood flow signal were not detected in all 7 cases. DA was remained in one case. Right ventricular pressure in all patients were improved, After 3 months, The remaining DA were not found. Cardiac structure and function in all patients were recovered to normal range. Conclusions Combined with tricuspid regurgitation and right ventricular pressure overload, echocardiography has significant value in diagnosis of prenatal closure and stenosis of DA.
