The objectives are to calculate values of distance between the aorta and superior mesentric artery (SMA) for body mass index of Indian population, to calculate normal distance between the aorta and SMA in different Body mass index categories in Indian population, to calculate the angles between the aorta and superior mesenteric artery in different sexes of Indian population and to establish normal values of angle between aorta and superior mesenteric artery in different sex categories in Indian population. A total of 300 patients were studied at our institute. Any patient undergoing Contrast enhanced CT abdomen scan and fulfilling criteria as described below- Patients of any gender with age more than 20 years. Normal serum creatinine values. Non allergic to iodinated contrast media. Patients refusing consent to study, having previous interventional surgery or history of duodenal obstruction was excluded from study. We studied 300 patients in four different BMI category groups for each sex. Mean values obtained from data of our study are different in all four BMI categories of same sex and different even in same BMI category of either sex. Overall mean values of both distance and angle between SMA and aorta were higher in males than females when compared for same BMI category group in Indian population. Knowledge of normal values of distance and angle between SMA and Aorta can help in diagnosis and may help in predicting patients at risk of developing SMA syndrome.
