Background: The superior mesenteric and celiac arteries separately originate from the aorta. Developmental changes can lead to the formation of a united celicaomesenteric trunk.Case presentation:  An ۸۳-year-old male with epigastric shooting pain radiating to the back was admitted to the hospital. Computed tomography angiography of the abdomen was performed to rule out dissection. Incidentally, a united celiacomesenteric trunk was observed. A long right renal artery directly originated from the aorta with a corkscrew appearance, and the left suprarenal and the left gastric arteries arose from the aorta with a common trunk.Conclusion: A united celiacomesenteric trunk can put the individual at risk of surgical complications and ischemia due to the lack of dual supply.
