Marginal artery of the colon Marginal artery of the colon In human anatomy, the marginal artery of the colon, also known as the marginal artery of Drummond and artery of Drummond is an artery that connects the inferior mesenteric artery with the superior mesenteric artery.

This artery is almost always present and its absence should be considered a variant.
