胎儿冠状静脉窦扩张的超声心动图诊断及误诊原因分析

Clinical significance of echocardiographic in fetal with coronary sinus dilation

目的:探讨胎儿冠状静脉窦扩张的超声心动图诊断临床意义及误诊原因分析。方法:2010年3月至2013年5月间,7 639例孕妇于我院接受产前胎儿超声心动图检查。结合出生后随访结果,回顾性分析冠状静脉窦扩张胎儿的超声心动图表现。结果:7 639例中共检出胎儿冠状静脉窦扩张60例(0.8%),其中单纯左位上腔静脉(PLSVC)28例(47%,28/60);合并心内其他畸形32例(53%,32/60)。初诊时误诊为原发孔房间隔缺损3例。结论:产前胎儿超声心动图可以诊断冠状静脉窦扩张及其合并心内畸形,对妊娠期胎儿的管理具有重要诊断价值和意义。

Objective：To analysis clinical significance of echocardiographic in fetal coronary sinus dila- tion. Methods：Totally 7639 pregnant women receive prenatal fetal echocardiography at our hospital from March 2010 to May 2013. Combined with follow-up results after birth, echocardiographic imaging of fetal with coronary sinus dilation were retrospectively analyzed. Results：Coronary sinus dilation was found in 60 fetuses. Among them, simply PLSVC 28 patients （47% , 28/60）, combined other cardiac malformations 32 cases （53%, 32/ 60）. Misdiagnosis of primum atrial septal defect 3 cases. Conclusion：Prenatal eehocardiography allows early diagnosis of coronary sinus dilation and combined with cardiac malformation, has important diagnostic value and clinical significance in the management of the fetus during pregnancy.
