The anatomical variations of the abdominal viscera are important due to its clinical importance. Various types of vascular anomalies are frequently found in human abdominal viscera during cadaveric dissection and diagnostic radiological imaging. The present report describes a variation in the branching pattern of right hepatic artery. Here right hepatic artery was arising from superior mesenteric artery, which was a direct branch from abdominal aorta. It was measuring 7 cm and was running behind portal vein. It is crucial for surgeons and radiologists to detect presence of a replaced right hepatic artery, not only for liver transplantation but before any abdominal surgery, as this unnoticed variant is vulnerable to inadvertent ligation.
