The "main classic branches" of the coeliac trunk are hepatic, splenic and left gastric arteries. The present variation was observed during the abdomen dissection classes for the medical under graduates, in the Department of Anatomy at Dr. Pinnamaneni Siddhartha Institute of Medical Sciences & Research Foundation, Gannavaram Mandal, Krishna District (AP), (INDIA), and a 52 year old male cadaver showed the coeliac trunk and superior mesenteric artery arose as common trunk from the ventral surface of the abdominal aorta at the level of the L1 vertebra. The coeliacomesenteric trunk is the rare variation. The incidence of coeliacomesenteric trunk variation was reported to be 2.7% by Parnanen and 1% by both Munger and Eaton. Complications in abdominal surgeries could be avoided with the accurate knowledge of the anatomical variations of coeliac trunk and superior mesenteric artery.
