To evaluate persistent left superior vena cava (PLSVC) cases according to associated cardiac, extracardiac, and chromosomal anomalies in the prenatal period and to review their outcomes.
The data of patients with a prenatal diagnosis of PLSVC between January 2013 and December 2017 were reviewed retrospectively.
Data of 32 cases were reviewed. Nineteen (60%) cases were associated with cardiac defects, 5 (15%) were associated with both cardiac and extracardiac defects, and 8 (25%) had no associated anomalies. Two fetuses had karyotype anomalies. All patients with isolated PLSVC survived. Among the cases associated with extracardiac anomalies, cardiac anomalies, and with both extracardiac and cardiac anomalies, the survival rate was 40%, 40%, and 25%, respectively. Outcome was more favorable in cases with isolated PLSVC (100% vs. 40%).
Prenatally diagnosed PLSVC is associated with cardiac and extracardiac anomalies in the majority of cases. The prognosis is good in isolated cases, but worsens when accompanied by cardiac or extracardiac anomalies.
根据产前时期相关的心脏、心外及染色体异常情况评估永存左上腔静脉（PLSVC）病例，并回顾其结局。
回顾性分析2013年1月至2017年12月期间产前诊断为PLSVC的患者数据。
共回顾了32例病例的数据。19例（60%）与心脏缺陷相关，5例（15%）与心脏和心外缺陷均相关，8例（25%）无相关异常。2例胎儿存在核型异常。所有单纯PLSVC患者均存活。在心外异常、心脏异常以及心外和心脏异常均有的病例中，存活率分别为40%、40%和25%。单纯PLSVC病例的结局更有利（100%对40%）。
产前诊断的PLSVC在大多数病例中与心脏和心外异常相关。单纯病例预后良好，但伴有心脏或心外异常时预后变差。
