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.Click to see full answer. Furthermore, is SMA Syndrome life threatening?SMA syndrome is a rare but life-threatening cause of abdominal pain and vomiting. SMA syndrome can occur in patients without chronic emesis.One may also ask, how do you get SMA syndrome? Superior mesenteric artery syndrome is caused when the third part of the duodenum is trapped or compressed between the two arteries – the aorta and the superior mesenteric artery. The intestine is a long, winding tube that connects the stomach to the anus. There is a small intestine and a large intestine. Similarly, what is the treatment for SMA syndrome? Surgical treatments include gastrojejunostomy, duodenojejunostomy, and division of the ligament of Treitz with mobilization of the duodenum. Laparoscopic treatment with a duodenojejunostomy has been successfully described and may become the standard of care for treatment of SMA syndrome.What is SMA in abdomen?In human anatomy, the superior mesenteric artery (SMA) arises from the anterior surface of the abdominal aorta, just inferior to the origin of the celiac trunk, and supplies the intestine from the lower part of the duodenum through two-thirds of the transverse colon, as well as the pancreas.
