<unk><unk><unk>  <unk>  is a gastro-vascular disorder in which the third and final portion of the duodenum is compressed between the abdominal aorta (AA) and the overlying<unk><unk><unk> . This rare, potentially life-threatening syndrome is typically caused by an angle of 6°–25° between the AA and the SMA, in comparison to the normal range of 38°–56°, due to a lack of retroperitoneal and visceral fat<unk>  fat). In addition, the aortomesenteric distance is 2–8 millimeters, as opposed to the typical 10–20. However, a narrow SMA angle alone is not enough to make a diagnosis, because patients with a low BMI, most notably children, have been known to have a narrow SMA angle with no symptoms of<unk> .<unk>  is also known as Wilkie's syndrome, cast syndrome,<unk>  root syndrome, chronic duodenal ileus and intermittent<unk> o-mesenteric occlusion. It is distinct from nutcracker syndrome, which is the entrapment of the left renal vein between the AA and the SMA, although it is possible to be diagnosed with both conditions.
