The coeliac trunk and superior mesenteric artery are the anterior visceral branches of the abdominal aorta. The anatomical variations of these arteries are due to development of the anterior splanchnic arteries. A case of coeliacomesenteric trunk was reported in this study which was observed in a 72-year-old male cadaver during the routine dissection. This trunk with a diameter of 13.98 mm is originated from the anterolateral wall of the abdominal aorta, 76.89mm below the aortic hiatus. After a 13.42 mm course, the trunk divided into coeliac trunk with a diameter of 7.09 mm and a superior mesenteric artery with the diameter of 5.25 mm. The coeliac trunk divided into splenic (6.85 mm diameter), common hepatic (5.31 mm diameter) and left gastric arteries (3.28 mm diameter). The superior mesenteric artery has inferior pancreaticoduodenal artery (3.20 mm diameter) arised from it as its first branch. Knowledge of variations of the coeliac trunk is important for both abdominal surgical approaches and radiological assessments.
