Measurement of the Distance and Angle Between the Aorta and Superior Mesenteric Artery on CT Scan: Values in Indian Population in Different BMI Categories.

The primary intention of the study was to "prove" that the reduced angle and distance between the superior mesenteric artery (SMA) and aorta significantly correlates with reduced body mass index (BMI). This in turn indicates the strong etiological role of this factor for causation of SMA syndrome. (Most literature till date still mentions sudden depletion of fat pad between the vessels as a "proposed predisposing factor").
