PY - 2022 T2 - Zollinger’s Atlas of Surgical Operations, 11e AB - Because of its embryologic development from both the midgut and hindgut, the colon has two main sources of blood supply: the superior mesenteric (1) and inferior mesenteric (2) arteries (bold numbers refer to parts of this chapter’s figure). The superior mesenteric artery (1) supplies the right colon, appendix, and small intestine. The middle colic artery (3) is the most prominent branch of the superior mesenteric artery. It arises after the pancreaticoduodenal vessels. The middle colic artery branches into a right and left division. The right division anastomoses with the right colic (4) and ileocolic (5) arteries. The left branch communicates with the marginal artery of Drummond (6). The middle and right colic and ileocolic arteries are doubly ligated near their origin when a right colectomy is performed for malignancy. The ileocolic artery reaches the mesentery of the appendix from beneath the terminal ileum. Angulation or obstruction of the terminal ileum should be avoided following ligation of the appendiceal artery (7) in the presence of a short mesentery.
