The celiac artery supplies blood to the liver, spleen and stomach. Among the issues that can arise from the superior mesenteric artery are those related to decreased blood supply coming through the vessel. Each bronchial artery (typically two on the left and one on the right) supplies systemic blood to the lungs and visceral pleura, in addition to the blood pumped to the lungs for oxygenation via the pulmonary circuit. This is called ischemia - an inadequate blood supply (circulation) to an organ due to blockage of blood vessels in the area.

The renal arteries send blood to the kidneys. During IMV ligation, inadvertent ligation of Arc of Riolan or meandering mesenteric artery around the IMV root "in type A&B" might result in compromised blood supply to the left colon, congestion, ischemia and different level of colitis or anastomotic dehiscence. The celiacomesenteric trunk (CMT) is a rare variant in which those arteries share a common origin from the abdominal aorta [1]. The mesenteric arteries take blood from the aorta and distribute it to a large portion of the gastrointestinal tract . When one or more of the mesenteric arteries narrow or become blocked, blood flow is restricted and the intestines fail to get enough oxygen. Blood supply to the abdominal organs is provided by three major unpaired vessels .

Proximally, its territory of distribution overlaps (forms a watershed . Mesenteric arches: branches of the vessels that supply blood to the intestinal tract. Ischemia means poor blood supply. The inferior mesenteric artery (IMA) branches from the abdominal aorta near the third lumbar vertebra and supplies the descending colon, sigmoid colon , and upper rectum with oxygenated blood [ 1, 28 ]. There are two mesenteric arteries in the human the superior and inferior. The mesentery is a fold of membrane that attaches the intestine to the abdominal wall and holds it in place. The liver sends blood to the inferior vena cava through the hepatic portal vein. This can happen both suddenly (acute mesenteric ischemia) or progressively over time (chronic mesenteric ischemia).

Our novel classification aims to distinguish different entities depending on the location and degree of tumor involvement of aRHA and propose a strategy to . It is the smallest of the three anterior visceral branches of the abdominal aorta. Branches of inferior mesenteric artery Left colic artery supplies the transverse and descending colon. In this article, we shall look at the anatomy of the inferior mesenteric artery - its anatomical position, major branches and clinical correlations. It arises from the abdominal aorta, and supplies arterial blood to the organs of the midgut - which spans from the major duodenal papilla (of the duodenum) to the proximal 2/3 of the transverse colon. Conclusion. Decreased blood flow can permanently damage the small intestine. These are called the mesenteric arteries. Contents 1 Structure Gross anatomy Location The superior mesenteric artery supplies blood to the intestines from the end of the duodenum through approximately half of the colon. Clinical Significance Because the common hepatic artery supplies blood to several organs, disorders of this artery can cause serious problems. If blood flow is very limited or suddenly blocked, such as by a blood clot, the intestines won't get enough blood. When one or more of the mesenteric arteries narrow or become blocked, blood flow is restricted and the intestines fail to get enough oxygen. It supplies arterial blood to the organs of the hindgut - the distal 1/3 of the transverse colon, splenic. If these vessels develop atherosclerosis or become occluded mesenteric ischemia can occur. .

Mesenteric vein thrombosis is an acute, subacute or chronic thrombosis of the superior mesenteric vein or inferior mesenteric vein or its branches. The inferior mesenteric artery (IMA) brings oxygen-rich blood to the large intestine, specifically to the upper region of the rectum and the left colic flexure, a bend at the intestine's left. In human anatomy, the superior mesenteric artery ( SMA) is an artery which arises from the anterior surface of the abdominal aorta, just inferior to the origin of the celiac trunk, and supplies blood to the intestine from the lower part of the duodenum through two-thirds of the transverse colon, as well as the pancreas .
