To highlight the importance of considering a single persistent left superior vena cava (PLSVC) in neonates with unexplained cyanosis.
Review of cases with neonates presenting with hypoxemia and cyanosis.
Assessment of responses to standard treatments.
Cyanosis in neonates persisted despite standard treatments.
Detection of PLSVC provided insight into the underlying cause.
Abstract
In conclusion, although rare, a single PLSVC should be considered in the differential diagnosis of neonates with persisting hypoxemia and cyanosis that do not respond to standard treatments.
