A rare variation of the incomplete coeliac trunk.

During the routine dissection course, we found a rare variation of the incomplete coeliac trunk in an 87-year-old Korean male cadaver. The left gastric artery, the splenic artery and the hepatomesenteric trunk arose independently from the abdominal aorta. The detailed branching pattern of this case could not be classified by classic classification systems, but belongs to type III' of Morita's classification. The accurate embryological knowledge on the arterial variations is important both to anatomists and to clinicians.
