	Chapter 30: Blood vessels, lymphatic drainage and nerves of the abdomen
		The external iliac artery descends in the iliac fossa and passes posterior to the inguinal ligament to become the femoral artery.
		The gonadal arteries arise inferior to the renal arteries (the gonads develop near the kidneys) and are either testicular or ovarian in distribution.
		Vagal fibers enter the celiac and superior mesenteric plexuses and are distributed to the derivatives of the foregut and midgut: stomach, liver, pancreas, and intestine as far as the left colic flexure.

	Chapter 8 - Section 3: First Principles of Gastroenterology
		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).

	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).

		Proximal collateral inflow arises from the oesophageal and inferior phrenic arteries; distal inflow arises from branches of the hypogastric arteries.

	eMedicine - Mesenteric Artery Thrombosis : Article Excerpt by: Deron J Tessier, MD
		Mesenteric artery thrombosis has the highest mortality rate of all causes of mesenteric ischemia.
		By the middle of the 20th century, it was generally understood that mesenteric ischemia was a manifestation of visceral atherosclerosis.
		During a period of low flow, the artery thromboses, and flow to the gut is compromised.

	Renal MRA (Site not responding. Last check: 2007-11-04)
		The celiac artery and superior mesenteric artery are medium sized arteries which arise from the anterior aspect of the aorta at T12 and L1 level, respectively.
		Thus a comprehensive renal artery imaging include identifying the number and origin of the renal arteries; detecting, localizing, and characterizing renal artery lesions; and defining the anatomy or pathologic involvement of adjacent vascular structures such as aorta, inferior vena cava, renal veins and mesenteric arteries.
		However the jejunal branches and the small branches of the mesenteric vessels are difficult to depict due to spatial resolution constraints, blurring due to peristalsis and cranial displacement from diaphragmatic movement and lastly due to chemical shift artefact as these arteries are embedded in fat.

	Visceral Artery Insufficiency
		Because of collateral flow via the middle colic artery branch of the SMA and the ascending colic artery of the IMA, the superior and inferior pancreaticoduodenal arteries, and the superior and inferior hemorrhoidal arteries, bowel ischemia does not occur until two of the three main visceral arteries are diseased severely.
		Mesenteric thrombosis causes occlusion at the origin of the vessel, while emboli most often lodge within the superior mesenteric artery usually at the first jejunal branch.
		Mesenteric vein occlusion is responsible for 5-15% of cases of acute mesenteric ischemia.

	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.
		The IMA is accompanied along its course by a similarly named vein, the inferior mesenteric vein, which drains into the splenic vein.

		The inferior vena cava is a large vein that returns blood from the blood in the lower part of the body.
		The ascending branches of the left colic artery forms anastomosis with the middle colic artery (a branch of the superior mesenteric artery) to form the marginal artery of Drummond.
		The blood supply to the duodenum comes from the superior pancreaticoduodenal arteries, branches of the celiac artery, and the inferior pancreaticoduodenal arteries, which are branches of the superior mesenteric arteries.

		The inferior mesenteric artery supplies the descending and sigmoid colon and the rectum.
		The ascending left colic branch of the inferior mesenteric runs upwards to the splenic flexure and forms an anastomosis with the middle colic artery through the formation of the marginal artery.
		There are three unpaired arteries which arise from the anterior aorta: the celiac trunk; the superior mesenteric artery; the inferior mesenteric artery.

		Once a diagnosis of acute mesenteric thrombosis is made, the patient should undergo operation because of the risk of bowel infarction, perforation, sepsis, and death.
		As previously mentioned, the splenic artery gives off the left gastroepiploic artery as well as the dorsal pancreatic artery, which supplies the body and tail of the pancreas and communicates with the anterosuperior pancreaticoduodenal and gastroduodenal arteries and sometimes the middle colic or SMA.
		The third important branch off of the celiac axis is the left gastric artery, which communicates with the right gastric artery along the posterior aspect of the lesser curvature of the stomach.

	Abdominal aorta Summary
		There is often a remnant of the umbilical artery, in the form of a fibrous strand that runs between the navel (umbilicus) and the superior mesenteric artery.
		The renal arteries usually branch from the abdominal aorta in between the celiac artery and the superior mesenteric artery.
		The abdominal aorta is covered, anteriorly, by the lesser omentum and stomach, behind which are the branches of the celiac artery and the celiac plexus; below these, by the lienal vein, the pancreas, the left renal vein, the inferior part of the duodenum, the mesentery, and aortic plexus.

	King Edward Memorial Hospital - Departments: Radiology - Interventional Case Records
		Abdominal visceral arterial color Doppler study a revealed complete occlusion of the celiac trunk and the superior mesenteric artery with near total occlusion of the inferior mesenteric artery.
		CT angiography is the preferred modality for the diagnosis and follow up of chronic mesenteric ischemia as it is non-invasive, easily reproducible and provides objective data for pre and post -operative comparison and to evaluate the exact extent of the disease.
		Although magnetic resonance imaging with angiography is an excellent tool for the evaluation of chronic mesenteric ischemia, it should not be the first technique used in the diagnosis of acute mesenteric ischemia, because of its potentially insufficient resolution to adequately identify non-occlusive low flow states or distal emboli.
