The coeliac trunk and superior mesenteric artery. are two vessels that supply a significant portion of the gastrointestinal tract. The separation of these two vessels from the abdominal aorta with a common stem is a rare and quite significant variation. 256 multidetector computed tomography angiography images of a 63 years old male patient were examined. In the evaluation, the coeliac trunk and superior mesenteric artery were separated from the anterior face of the abdominal aorta at the lower level of the first lumbal vertebra as a common trunk. In addition, it was observed that the left gastric artery originated from the hepatic artery proper. Variations of the coeliac trunk are highly important in liver transplants, gallbladder and gastric region surgery, as well as interventional radiological processes.
