Also known as Wilkie's syndrome, this condition occurs when the third part of the duodenum is compressed between the superior mesenteric artery and the aorta. Under normal conditions, there is retroperitoneal fat around the third part of the duodenum, which avoids compression by creating an aortomesenteric angle > 28º.

== Epidemiology ==
* Females (10-39 years old)

'''Risk factors:'''
* Previous accentuated weight loss
* Previous surgery for scoliosis
* Anatomical variations in the ligament of Treitz, with consequent elevation of the duodenum

== Signs and symptoms ==
* Postprandial upper abdominal pain that is relieved in ventral or left lateral decubitus
* Nausea
* Emesis
* Eeight loss

== Diagnosis ==
* Symptoms of duodenal obstruction associated with:
** Aortomesenteric angle <25º
** Aortomesenteric distance <8 mm
