2021年7月26日 · The superior mesenteric artery plays a vital role in keeping the digestive system healthy and functioning. If the artery clogs with plaque or develops a clot, blood flow to digestive organs slows. Rarely, the superior mesenteric artery presses against a renal vein or the duodenum, causing potentially life-threatening problems.

2024年4月20日 · 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.

2023年7月25日 · The superior mesenteric artery arises from the abdominal aorta at the level of the first lumbar vertebral body L1, approximately a centimeter below the coeliac trunk. It arises above the renal arteries (that arise at vertebral level L1-L2). The superior mesenteric artery supplies the midgut, while the inferior mesenteric artery supplies the ...

2024年4月20日 · Inferior mesenteric artery – supplies the organs of the hindgut – the distal one third of the transverse colon, splenic flexure, descending colon, sigmoid colon and rectum. The venous drainage of the mesentery is via the superior mesenteric vein (SMV) and inferior mesenteric vein (IMV), which both run alongside their associated arteries.

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.

2023年7月24日 · 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. Marginal Artery of Drummond.

2024年2月22日 · A centimetre or so below the celiac trunk, the superior mesenteric artery emerges from the abdominal aorta at the level of the first lumbar vertebral body L1. It emerges at the level of the vertebrae L1–L2, above the renal arteries. The inferior mesenteric artery supplies the hindgut, while the superior mesenteric artery supplies the midgut.

2025年1月24日 · The superior mesenteric artery (SMA) plays a critical role in supplying oxygenated blood to a large portion of the gastrointestinal (GI) tract. Specifically, it provides blood to most of the small intestine and parts of the large …

The superior mesenteric artery (SMA) is the artery of the midgut, and it arises from the front of aorta below the celiac trunk at the level of the lower border of L1 vertebral body (Fig. 15-17). The SMA supplies the entire small bowel (except the proximal duodenum) and the large colon up to the proximal half of transverse colon.

Superior mesenteric artery provides blood supply to the digestive system organs in the abdominal cavity. BRANCHES. 1. Its first branch is the inferior pancreaticoduodenal artery, which will anastomose with the superior pancreaticoduodenal artery coming from the Celiac Truncus. 2.
