Which of the following blood vessels is Drummond's Aery?
High-Yield Explanation
A = Marginal Aery of Drummond B = Inferior mesenteric aery C = Superior rectal aery D = Ileocolic aery Marginal aery of Drummond forms a continuous aerial circle along the inner border of the colon. Straight vessels (Vasa recta) arise from the aery to supply the colon. It is formed by the union of several branches; the ileocolic, right colic and middle colic of the SMA and left colic and sigmoid branches of the IMA. Also remember Arc of Riolan - anastamosis between the middle colic branch of SMA and the left colic branch of IMA. It is less common than the marginal aery, and its existence has been questioned by some surgeons.
