What is inferior mesenteric artery?
The inferior mesenteric artery, the smallest of the mesenteric arteries, is an anterior branch of the abdominal aorta. It continues in the pelvis as the superior rectal artery. It supplies the distal transverse colon, splenic flexure, descending and sigmoid colon, and the upper part of the rectum.
What is the function of the inferior mesenteric?
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 side.
What is superior and inferior mesenteric artery?
These organs are part of the digestive system. The artery branches off of the aorta, which is the body’s largest blood vessel. Superior refers to the artery’s location above other arteries that supply the intestines. A related artery, the inferior mesenteric artery, supplies the lower gastrointestinal (GI) tract.
What is inferior artery?
The inferior mesenteric artery (IMA) is a major branch of the abdominal aorta. It supplies arterial blood to the organs of the hindgut – the distal 1/3 of the transverse colon, splenic flexure, descending colon, sigmoid colon and rectum.
Where is inferior artery?
In human anatomy, the inferior mesenteric artery, often abbreviated as IMA, is the third main branch of the abdominal aorta and arises at the level of L3, supplying the large intestine from the distal transverse colon to the upper part of the anal canal.
What is the SMA artery?
The superior mesenteric artery supplies the midgut from the ampullary region of the second part of the duodenum to the splenic flexure of the large intestine. The inferior pancreaticoduodenal artery arises from the SMA and, along with the superior pancreaticoduodenal artery, supplies the head of the pancreas.
What is mesenteric artery?
What is the size inferior mesenteric artery?
Results: The length of the inferior mesenteric artery varied widely, from 10.1 to 82.2 mm. In 41.2% patients, the left colic artery arose independently from the sigmoid artery, and in 44.7% of the patients, the left colic artery and sigmoid artery had a common trunk, whereas the left colic artery did not exist in 5.1%.
Where does inferior mesenteric artery branch from?
the abdominal aorta
The inferior mesenteric artery (IMA) is one of the three non-paired major splanchnic arteries, in the abdominal cavity, arising from the abdominal aorta and supplying the hindgut. It is the smallest of the three anterior visceral branches of the abdominal aorta.
Where is SMA artery?
The superior mesenteric artery (SMA) is a major artery of the abdomen. 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.
What structures does the inferior mesenteric artery supply?
The inferior mesenteric artery, also a branch of the abdominal aorta, supplies the distal third of the transverse colon, the descending colon and sigmoid colon, and the superior portion of the rectum as the superior hemorrhoidal artery.
Where is the mesenteric artery?
The superior mesenteric artery arises from the abdominal aorta just below the celiac artery. Its branches supply the small intestine and part of the large intestine.
What is the mesentery organ?
Abstract. The mesentery is the organ in which all abdominal digestive organs develop, and which maintains these in systemic continuity in adulthood. Interest in the mesentery was rekindled by advancements of Heald and Hohenberger in colorectal surgery.

What is mesenteric mean?
/mes.ənˈter.ɪk/ relating to the mesentery (= the membrane that connects the bowel to the back wall of the abdomen): the inferior mesenteric artery.
What is the function of the inferior messentric artery?
Strong’s procedure: Where the duodenum is re-positioned to the right of the superior mesenteric artery
What does superior mesenteric artery mean?
The superior mesenteric artery is one of the main arteries of the abdomen. It runs from the abdominal portion of the aorta to the third section of the small intestine, the ileum. Mesenteric refers to the mesentery, which is a fold of tissue that anchors the small intestine to the abdominal wall.
What does superior mesenteric artery syndrome stand for?
Superior mesenteric artery syndrome (SMAS) is a digestive condition that occurs when the duodenum (the first part of the small intestine) is compressed between two arteries (the aorta and the superior mesenteric artery). This compression causes partial or complete blockage of the duodenum. [1]
What causes superior mesenteric artery (SMA) syndrome?
arteriomesenteric duodenal obstruction
