Superior mesenteric artery syndrome: spectrum of CT findings with multiplanar reconstructions and 3-D imaging.
OBJECTIVE
This article reviews the causes, clinical presentation, and CT diagnosis of superior mesenteric artery (SMA) syndrome.


CONCLUSIONS
In conjunction with an appropriate clinical history, several CT findings can suggest the diagnosis of SMA syndrome. These findings include narrowing of the aortomesenteric angle and distance, distension of the stomach and duodenum, and dilatation of the left renal vein with left-sided venous collaterals.
