Superior Mesenteric Artery Sma Course Divisions Termination 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 m. The superior mesenteric vein (smv) should be positioned to the right of the sma, especially the first 3 cm distal to its origin. reversal of sma smv relationship is classically associated with intestinal malrotation, although distally (>6 cm from origin) this may be a normal finding 6. supply. the superior mesenteric artery is the artery to the.
Superior Mesenteric Artery вђ Earth S Lab The superior mesenteric artery gives rise to numerous arteries that supply the jejunum and ileum. the arteries pass between the layers of the mesentery and form anastomotic arcades – from which smaller, straight arteries (known as the “vasa recta”) arise to supply the organs (fig 2). the jejunal blood supply is characterised by a smaller. The blood supply to the rectum arises from the superior, middle and inferior rectal arteries. 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). Superior mesenteric artery (sma) syndrome (also known as wilkie's syndrome, cast syndrome, or aorto mesenteric compass syndrome) is an obstruction of the duodenum caused by extrinsic compression between the sma and the aorta. the median age of patients is 23 years old (range 0 91 years old) and predominant in females over males with a ratio of 3:2. Superior mesenteric artery syndrome is a rare cause of proximal small bowel obstruction and is linked to notable morbidity and mortality when the diagnosis is delayed. while superior mesenteric artery syndrome is rare, the morbidity and mortality associated with its complications make it a crucial differential to consider when concerned for bowel obstruction, especially in the setting of.
