Marginal artery of the colon 2395960 211987403 2008-05-12T23:29:12Z 138.9.24.12 /* Clinical relevance */ {{Infobox Artery | Name = {{PAGENAME}} | Latin = arteria marginalis coli | GraySubject = | GrayPage = | Image = Inferior_mesenteric_a.gif | Caption = 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). | Image2 = | Caption2 = | BranchFrom = [[superior mesenteric artery]], [[inferior mesenteric artery]] | BranchTo = | Vein = | Supplies = [[large intestine]] | MeshName = | MeshNumber = | DorlandsPre = a_61 | DorlandsSuf = 12154972 | }} 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 [[England|English]] [[physician]]),<ref>{{WhoNamedIt|synd|3682}}</ref> 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 artery|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|abdominal aortic aneurysm repair]] the inferior mesenteric artery does not have to be re-implanted (re-attached) into the repaired [[abdominal aorta]]. The Marginal Artery of Drummond runs in the [[mesentery]] close to the bowel as part of the vascular arcade that connects the SMA and IMA. This artery is almost always present and its absence should be considered a variant. The Arc of Riolan, also known as the Meandering Mesenteric artery, is another vascular arcade present in the colonic mesentery that connect the proximal Middle Colic artery with the proximal IMA. This artery is found low in the mesentery, near the root. ==See also== *[[Marginal branch of the right coronary artery]], sometimes referred to as the ''marginal artery''. *[[Marginal artery]] ==References== <references/> ==External links== *[http://umanitoba.ca/faculties/medicine/units/anatomy/bmr/ABDOMEN.htm Abdomen] - [[University of Manitoba]] * {{Medcyclopaedia|ii/m/MARGINAL_ARTERY_OF_DRUMMOND}} * {{eMedicineDictionary|Marginal+artery+of+colon}} * {{SUNYAnatomyFigs|39|01|02}} - "Branches of the superior mesenteric artery." * {{SUNYAnatomyFigs|39|02|02}} - "Branches of the inferior mesenteric artery." *[http://www.merck.com/media/mmhe2/figures/fg020_2.gif Figure of the marginal artery of the heart] - merck.com. {{Arteries of thorax and abdomen}} [[Category:Arteries]] [[Category:Abdomen]]
