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.
