Knowledge of the branching pattern of the abdominal aorta is clinically important for any abdominal surgeon operating on parts of the gut or neighboring structures like the suprarenals, spleen, pancreas, liver, kidneys and ureter. The presence of abnormal inferior phrenic artery associated with aberrant branch from the celiac trunk supplying the pancreas and duodenum is a rare anomaly. In the present case, we observed four branches of the celiac artery i.e. (a) left gastric artery (b) common hepatic artery (c) splenic artery and (d) an aberrant branch, which took a course inferiorly towards the pancreas. The aberrant artery supplied the body of the pancreas and gave a branch which supplied the horizontal part of the duodenum and then entered the transverse mesocolon to supply the hepatic flexure and some portions of the ascending and the transverse colon. The inferior phrenic artery was absent on the left side. Concomitant anomalies of such type are to be kept in mind by the surgeon, while operating cases of carcinoma head of pancreas and performing kidney transplantations.
