Artery: Marginal artery of the colon
Frontal view of the abdominal aorta and the territory supplied by the inferior mesenteric artery. The arteries on the right side (left side of image) arise from the superior mesenteric artery (SMA). The marginal artery (not labeled) connects the middle colic artery (a branch of the SMA) to the left colic artery (a branch of the IMA).
Latin	arteria marginalis coli

In human anatomy, the marginal artery of the colon, also known as the marginal artery of Drummond and artery of Drummond (named after Sir David Drummond (1852-1932) an English physician), is a blood vessel that anastomoses (connects) the inferior mesenteric artery (IMA) with the superior mesenteric artery (SMA). It is sometimes absent, as an anatomical variant.

Clinical relevance

Along with branches of the internal iliac arteries, it is usually sufficiently large to supply the oxygenated blood to the large intestine covered by the inferior mesenteric artery and is a reason that in abdominal aortic aneurysm repair the inferior mesenteric artery does not have to be re-implanted (re-attached) into the repaired abdominal aorta.
