Isolated Persistent Left Superior Vena Cava Associated With Autosomal Dominant Polycystic Kidney Disease (ADPKD): Challenges and Clinical Significance.

Persistent left superior vena cava (PLSVC) is the most common venous anomaly of the thorax that usually coexists with the right superior vena cava. However, in a minority of cases, there is only a PLSVC without a right superior vena cava which is called an isolated PLSVC. There are some reported anomalies that can co-occur with PLSVC; yet, none have reported an association with autosomal dominant polycystic kidney disease (ADPKD).
