Double Left Brachiocephalic Vein in an Adult Patient Who Underwent Cardiac Surgery: A Case Report

Abstract

Background: A double left brachiocephalic vein is an extremely rare venous anomaly. Case presentation: Herein, we present the case of a 79-year-old woman with a double left brachiocephalic vein who underwent cardiac surgical procedures. The normal left brachiocephalic vein was patent, and the accessory left brachiocephalic vein passed across the heart and aorta in front of the pericardium and drained into the superior vena cava. She underwent surgical ligation of the accessory left brachiocephalic vein, followed by an aortic valve replacement and coronary artery bypass grafting. Her postoperative recovery was uneventful, without any venous complications from the ligation of the accessory vein. The patient is doing well one year after the surgery.Conclusions: The presence of double left brachiocephalic veins should be recognized before cardiac surgery in order for us to avoid intraoperative technical issues concerning this venous anomaly and unpredictable intraoperative bleeding due to injury of the accessory left brachiocephalic vein.
