Anomalous Left Brachiocephalic Vein Draining into the Right Internal Thoracic Vein: A Case Report

Year: 2026

Type: article

Abstract: The left brachiocephalic vein (LBCV) rarely exhibits an anomalous course and its major patterns have been described in several studies. Although LBCV anomalies are mostly asymptomatic, their identification and recognition are important in clinical settings such as cardiovascular intervention or surgery. Herein, we report a rare anomalous LBCV that was incidentally detected on chest computed tomography in a 59-year-old female. Instead of directly draining into the superior vena cava (SVC), this anomalous LBCV travelled an extraordinarily long, downward trajectory to drain into the right internal thoracic vein and consequently into the SVC.
