Persistent left superior vena cava (PLSVC), Central line


Persistent Left Superior Vena Cava (PLSVC) is rare but important congenital vascular anomaly. It results when the left superior cardinal vein caudal to the innominate vein fails to regress. It is most commonly observed in isolation but can be associated with other cardiovascular abnormalities. The presence of PLSVC can render access to the right side of heart challenging via the left subclavian approach, which is a common site of access utilized. Incidental notation of a dilated coronary sinus on echocardiography should raise the suspicion of PLSVC. Here we present a case of PLSVC that was discovered in an infant accidently after central line insertion.
