Introduction: Knowledge of variation of coeliac trunk is fundamental for a correct pre operative vascular planning in surgical and radiological abdominal procedures like liver transplantation, hepatic arterial infusion, and chemotherapy via catheters for therapy of unresectable advanced liver malignancies.
Materials and methods: Present observation about Quadrifurcated coeliac trunk and anomalous origin of right hepatic artery was noted in an adult male cadaver during routine dissection in Department of Anatomy, Government Medical College and Hospital, Chandigarh.
Observations: Besides giving origin to 3 known branches (common hepatic artery, left gastric artery, splenic artery), there was a branch (right hepatic artery) which arose from right side of coeliac trunk posterior to other 3 branches, passed posterior to bile duct, crossing it from left to right, entered through right end of porta hepatis, and was supplying right lobe of liver.
Conclusion: Persistence of the longitudinal ventral arterial segment connected to the coeliac trunk may be considered as the reason for right hepatic artery originating from coeliac trunk.
Bile duct (BD), coeliac trunk (CT), common hepatic artery (CHA), Gastro duodenal artery (GDA), Hepatic artery proper (HAP), splenic artery (SA), Left gastric artery (LGA), right hepatic artery (RHA).
