Analysis of the Variations in the Colic Branching Pattern of the Superior Mesenteric Artery: A Cadaveric Study With Proposal to Modify Its Current Anatomical Classification.

Background: Vascular anatomy of the ascending colon is more complex and variable as compared to the left. Variations range from the mode of origin, branching to territorial supply. The present study was undertaken to learn the anatomical variations of the superior mesenteric artery (SMA) and its colic branches in detail.
