Based on the radiological measurement of aortomesenteric angle and aortomesenteric distance between the superior mesenteric artery and abdominal aorta, in addition to the electrolyte imbalance and clinical history of persistent vomiting, the diagnosis of superior mesenteric artery syndrome was made.

SMA syndrome is a rare acquired vascular compression disorder in which acute angulation of the superior mesenteric artery (SMA) results in compression of the third part of the duodenum, leading to proximal bowel loops obstruction.

Patient was treated with parenteral nutrition and supplements initially. He gained weight with reduction of the vomiting symptoms as well as improvement of the electrolyte imbalance in clinic follow up.

Compression of the left renal vein at this region is being named as nutcracker syndrome.
