A rare case of left hepatic vein anomalous drainage to the coronary sinus

The left hepatic vein (LHV) anomalous drainage into the coronary sinus (CS) is an extremely rare congenital vascular abnormality. It is usually asymptomatic, but it has surgical implications if the patient undergoes cardiac, vascular or hepatic procedures. We report a case of a 90-year-old man who had an isolated LHV anomalous drainage diagnosed on a computed tomography performed to evaluate fatigue. The diagnosis of LHV drainage into the CS during preoperative evaluation can avoid intraoperative complications and may determine the preferred surgical approach.
