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.

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).

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.

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.

2024年12月19日 · The superior mesenteric artery (SMA) is one of the three non-paired major splanchnic arteries in the abdominal cavity arising from the abdominal aorta and supplying the midgut; i.e. from mid duodenum to distal transverse colon.

2024年11月13日 · The superior mesenteric artery (SMA) is a major artery that branches off from the abdominal aorta and provides oxygenated blood to a large portion of the digestive system. Specifically, the SMA supplies the small intestine, parts of the colon, and the pancreas.

2020年12月17日 · The superior mesenteric artery supplies the midgut. The midgut is the section of the intestine which runs from just below the major duodenal papilla through two-thirds of the way across the transverse colon. What we can see here is that just above the superior mesenteric artery is this celiac artery.

2025年1月24日 · The superior mesenteric artery (SMA) is a major artery arising from the anterior surface of the abdominal aorta. It typically originates at the level of the first lumbar vertebra (L1), just below the celiac trunk.[6]

2024年2月22日 · The superior mesenteric artery (SMA) is a major blood vessel in the human body, arising from the abdominal aorta just below the celiac artery at the level of the first lumbar vertebra. It begins at the level of the L1 vertebrae on the anterior surface of the aorta, about 1 centimetre below the celiac trunk and above the renal arteries.

2023年7月24日 · Superior mesenteric artery syndrome occurs when the third and fourth portions of the duodenum become compressed between the abdominal aorta and the superior mesenteric artery. Its symptoms include early satiety, nausea, vomiting, and sharp postprandial abdominal pain due to small bowel obstruction.
