	Marginal artery - Wikipedia, the free encyclopedia
		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).
		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.
		Marginal artery also refers to a major branch of the right coronary artery (RCA) that rises in proximity to where the RCA passes around the lateral margin (or side) of the heart (to its posterior aspect).

	Marginal artery
		In human anatomy, the marginal artery, 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 with the superior mesenteric artery.
		It is 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.
		Marginal artery also refers to a major branch of the right coronary artery (RCA) that rises in close proximity to where the RCA passes around the lateral margin (or side) of the heart (to its posterior aspect).

	Inferior mesenteric artery - Wikipedia, the free encyclopedia
		In human anatomy, the inferior mesenteric artery, often abbreviated as IMA, supplies the large intestine from the left colic (or splenic) flexure to the upper part of the rectum, which includes the descending colon, the sigmoid colon, and part of the rectum.
		Proximally, its territory of distribution overlaps (forms a watershed) with the middle colic artery, and therefore the superior mesenteric artery.
		The IMA branches off the anterior surface of the abdominal aorta, approximately midway between the renal artery branch points and the abdominal aortic bifurcation (into the common iliac arteries).

		For instance, the artery for the right angle and artery for the transverse colon can arise from the middle colic artery or there may be accessory arteries for the artery for the transverse colon or accessory arteries for the left colic artery.
		The middle colic is often the marginal artery for the major portion of its distribution.
		In addition, the artery for the right angle and the artery for the transverse can arise from the middle colic or there may be accessory arteries for the artery for the transverse colon or accessory arteries for the left colic artery.

	Gastroenterology Chapter 8 Mesenteric Vasculature
		The blood flow to the splanchnic organs is derived from three main arterial trunks: the celiac, the superior mesenteric artery and the inferior mesenteric artery.
		The celiac artery supplies blood to the foregut (stomach and duodenum), the superior mesenteric artery supplies blood to the midgut (duodenum to transverse colon), and the inferior mesenteric artery is responsible for blood to the hindgut (transverse colon to the rectum).
		The superior mesenteric and inferior mesenteric systems are joined by the arch of Riolan and the marginal artery of Drummond, vessels that connect the middle colic artery (a branch of the superior mesenteric artery) and the left colic artery (a branch of the inferior mesenteric artery).

		The coronary artery consists of a large left anterior descending artery which is associated with 60% stenosis but a large obtuse marginal artery which has a tight proximal stenosis.
		Because the radial artery appeared to be a good conduit The patient would have arterial graft to the left anterior descending artery territory.
		The first obtuse marginal artery was a very large target and the vein graft to this target indeed produced an excellent amount of flow.

		The arteries that supply the heart are coronary arteries; the veins of the heart are known as the cardiac veins.
		The right coronary artery originates from the right aortic sinus and passes to the right, behind the pulmonary trunk, to run downward in the coronary sulcus between the right atrium and the right ventricle.
		The circumflex branch ultimately runs toward the left coronary artery in the coronary sulcus, however, first it runs between the left auricle and left ventricle, and then circles to the posterior aspect of the heart.
