Abstract
Background: Knowledge of hepatic arterial vascularization and its variations have a significant
relevance for the daily practice of hepato-biliary surgeon as well as radiologists and anatomists.
The right hepatic artery normally arises from the hepatic artery proper, the continuation of the
common hepatic artery which is a branch of celiac trunk. Sometimes the anatomical arterial
variations are also very common in human beings especially in hepatic region. During routine
dissections for undergraduate medical students at Department of Anatomy, in a 75 -year-old
male cadaver, we found the right accessory hepatic artery arises from the superior mesenteric
artery which supplied the right lobe of the liver along with normal right hepatic artery. In addition,
a direct branch to the left lobe of the liver was seen arising from common hepatic artery. The
arterial anomaly can be enlightened by embryonic development. The knowledge of existence
of aberrant hepatic arteries, either accessory or replacing, is important because they may
influence surgical and interventional radiological procedures.
