There is an anomalous vessel coursing inferiorly to the left of the aortic arch and anterior to the left hilum. It is in direct continuation with the confluence of the left subclavian vein and the left internal jugular vein. Superiorly, it is communicating with a normal right sided SVC via a hypoplastic left brachiocephalic vein. Inferiorly, it drains into the coronary sinus, and thus into the right atrium. Findings are consistent with double SVC due to the presence of a persistent left SVC (anatomical variant) along with a normal right SVC.
