"Marginal artery of Drummond"
"The terminal branches of the superior mesenteric artery (ileocolic, right colic, middle colic) and inferior mesenteric artery (left colic, sigmoid) which supply the colon are linked together by a continuous arterial circle or arcade along the mesenteric border, known as the marginal artery of Drummond. This arcade is considered a normal structure, although may be absent in some people. It may supply collateral flow between the superior and inferior mesenteric artery circulations 3. From this marginal artery, straight vessels (also known as vasa recta) pass to the colon."
