摘　　要：目的探讨胎儿永存左上腔静脉产前超声表现和产前超声诊断价值。方法 2009年12月-2013年7月该院产前超声共检出永存左上腔静脉胎儿133例,回顾性分析永存左上腔静脉胎儿超声心动图表现及合并相关疾病特点。结果 133例永存左上腔静脉中57例为单纯永存左上腔静脉,54例合并心内异常,15例合并心外异常,7例同时合并心内心外异常。结论永存左上腔静脉常合并心内和心外异常,与胎儿畸形关系密切。永存左上腔静脉是产前筛查胎儿畸形的重要标志。产前超声诊断永存左上腔静脉具有重要的临床意义。【Objective】 To evaluate the associated conditions and appearances of persistent left superior vena cava detected by ultrasound. 【Methods】 Totally 133 fetuses had been diagnosed PLSVC by prenatal ultrasound in our hospital from December 2009 to July 2013. Echocardiographic performances of fetuses with PLSVC and the characteristics of associated complications were retrospectively analyzed. 【Results】 Among the133 fetuses complicated with PLSVC, 57 had no associated condition, 54 had cardiac anomalies, 15 had extracardiac anomalies, and the remaining 7 had both cardiac and extra cardiac anomalies. 【Conclusion】PLSVC is frequently associated with cardiac and extracardiac anomalies and it is closely related with fetal malformations. PLSVC is an important indicator in screening fetal defects. Prenatal echocardiographic diagnosis of persistent left superior vena cava has a great clinical significance.
