OP04.12: Prenatal diagnosis of persistent left superior vena cava: associated defects and outcome

Abstract

Objective: To evaluate the associated cardiac (CHD) and extracardiac defects and the outcome of fetuses with prenatal diagnosis of persistent left superior vena cava (PLSVC) Methods: Retrospective study of all cases with PLSVC prenatally diagnosed in a single tertiary referral center between 2000 and 2005.

Ultrasonographic features of the persistence of superior left vena cava and pathological cardiac associations in fetus. Case series.

“…Regarding the prognosis, if PLSVC is isolated the prognosis is excellent, the anomaly being asymptomatic [16]. Otherwise, there is a significant morbidity and mortality, which results especially from the associated abnormalities [10,12,13,17].…”

“…Otherwise, there is a significant morbidity and mortality, which results especially from the associated abnormalities [10,12,13,17]. Identification in the fetal life of the PLSVC increases the risk of cardiac malformation by 50 times [16]. Identification of an associated complex fetal cardiac anomaly is a sign of bad prognosis [18].…”
