摘要目的 探讨胎儿期永存左上腔静脉声像图特征及临床应用价值.方法 应用胎儿超声心动图检查3368例胎儿,检出31例胎儿永存左上腔静脉及相关畸形.结果 胎儿超声心动图显示,31例胎儿中30例合并冠状静脉窦扩张,14例合并其他心血管异常,6例合并心外畸形,4例同时合并心内外畸形.结论 永存左上腔静脉常合并先天性心脏病,胎儿预后取决于有无合并其他先天性心脏病,产前诊断永存左上腔静脉可帮助正确评估胎儿预后.

abstractsObjective To evaluate the ultrasonic feature and clinical significance of persistent left superior vena cava(PLSVC)in fetal life.Methods Fetal echocardiography was performed in 3368 fetuses.Thirty-one fetuses of PLSVC were confirmed.Results The dilated coronary sinus was observed in 30 of 31 fetuses.Congenital heart defects were presented in 14 of these cases,and extracardiac anomalies were presented in 6 fetuses.Both congenital heart defects and extracardiac anomalies were observed in 4 fetuses.Conclusions PLSVC is always associated with congenital heart defects.The prognosis Of affected fetuses largely depends on whether or not the PLSVC is associated with a congenital heart defect.Prenatal diagnosis of PLSVC can help US plan perinatal counseling and ameliorate the postnatal course.
