Abstract

The arterial vascularization of the gastrointestinal tract comprises mainly three arteries, the coeliac trunk, and both superior and inferior mesenteric arteries. The anastomoses joining these three levels of arteries are welldocumented and include arcades of Riolan, Villemin, Bühler, and marginal artery of Drummond. These provide efficient collateral circulation when needed and hence utilized for planning surgical intervention of colon. The present case describes an anastomotic channel, commencing from the dorsal pancreatic artery, and directly connecting all the three levels together that can be explained embryologically. The clinical significance of the present case has been discussed.
