This case report highlights a rare congenital anomaly of the superior vena cava causing polycythemia and paradoxical embolization, which was managed with corrective surgery.
An unusual cause of polycythemia, cyanosis and paradoxical embolus is described in a 37-year-old man, consisting of a rare congenital anomaly of the superior vena cava (SVC). The right-sided SVC received pulmonary venous drainage from the right lung and drained, through two channels, into both atria with the left atrium receiving the larger of the two channels. The atrial septum was intact. Corrective surgery and postoperative cardiac catheterization are described and the literature concerning anomalies of the right superior vena cava is reviewed.

Shapiro et al. (1981) conducted a case report in Congenital anomaly of the superior vena cava presenting with polycythemia, cyanosis and paradoxical embolus (n=1). Corrective surgery was evaluated. Corrective surgery was described for a 37-year-old man with a rare congenital anomaly where the right superior vena cava drained into both atria, causing polycythemia and paradoxical embolization.
