A CASE REPORT : A CASE OF SUPERIOR MESENTERIC ARTERY SYNDROME

Superior mesenteric artery (SMA) syndrome is an uncommon but well recognized clinical entity characterized by compression of the third, or transverse, portion of the duodenum between the aorta and the superior mesenteric artery. This results in chronic, intermittent, or acute complete or partial duodenal obstruction. Superior mesenteric artery syndrome was rst described in 1861 by Von Rokitansky, who proposed that its cause was obstruction of the third part of the duodenum as a result of arterio-mesenteric compression. Some studies report the incidence of superior mesenteric artery syndrome to be 0.1- 0.3%.
