Inadvertent Placement of Tunneled Hemodialysis Catheter in Persistent Left Superior Vena Cava.

Persistent left superior vena cava (PLSVC) is the most common congenital intrathoracic venous anomaly with significant clinical relevance. In the vast majority of cases, it is asymptomatic and diagnosed after noticing an abnormal course of central venous access device on a routine post-procedure roentgenogram.
