摘　　要：目的 探讨胎儿永存左上腔静脉(PLSVC)合并心内畸形类型及妊娠演变。方法 基于云南大学附属医院影像采集及病例系统中90例永存左上腔静脉胎儿病例资料,回顾分析胎儿合并的心内、外畸形类型,妊娠结局。结果 (1)76例(84.4%)胎儿在22~24周系统超声检查时诊断PLSVC,14例(15.6%)胎儿在晚孕期发现;(2)90例胎儿中,合并心内异常26例(28.9%),合并心外异常21例(23.3%),未合并异常50例(55.5%);(3)心内异常以主动脉弓缩窄或弓发育不良最常见(34.6%),其次为室间隔缺损(26.9%),心外异常以单脐动脉最常见(15.6%)。结论 永存左上腔静脉与先天性心脏病关系密切;对于发现PLSVC的胎儿,孕期加强心功能观测;产前超声筛查在四腔及三血管切面基础上增加无名静脉切面,提高PLSVC检出率。Objective To investigate the type and pregnancy evolution of persistent fetal left superior vena cava(PLSVC)complicated with intracardiac malformations.Methods The data of 90 fetal cases with persistent left superior vena cava were collected via imaging and patients’case system of the Affiliated Hospital of Yunnan University.The types of congenital and external malformations and pregnancy outcomes of the fetus were retrospectively analyzed.Result PLSVC was diagnosed in 76(84.4%)fetuses at 22-24 weeks of systemic ultrasonography,and 14(15.6%)fetuses were found in late pregnancy.Among the 90 fetuses,26(28.9%)had combined intracardiac anomalies,21(23.3%)had combined extracardiac anomalies,and 50(55.5%)had uncomplicated anomalies.The most common intracardiac anomaly was aortic arch narrowing or arch dysplasia(34.6%),followed by ventricular septal defect(26.9%),and the most common extracardiac anomaly was single umbilical artery.Conclusion The persistent left superior vena cava is closely related to congenital heart disease.For fetuses with PLSVC,observation of cardiac function should be strengthened during pregnancy.In prenatal ultrasound screening,the section of innominate vein should be added to the section of four cavities and three vessels to improve the detection rate of PLSVC.
