Morphological characteristics of origin of superior arterial mesenteric trunk

Our study was conducted on a total of 46 CT angiographies, performed on a GE LightSpeed VCT 64-slice CT installation. Benchmarks were followed in relation to the gender of the person examined. The origin of the superior mesenteric artery relative to the spine we found it in a range between T12 vertebra and L1-L2 intervertebral disc. The T12 vertebra origin was localized in 2 cases (4.35% of cases), both in women. Superior mesenteric artery originated at the level of L1 in 78.26% (90.91% of male cases and in 66.67% of women cases). In 8 cases (17.39% of cases) the origin of the superior mesenteric artery was located at the L1-L2 intervertebral disc. Endolumenal vertical diameter of the superior mesenteric artery orifice we found it in the range of 5.6 to 10.9 mm (6.9 to 10.9 mm in men, and 5.6 to 8.6 mm in women). Horizontal diameter sizes ranged from 4.9 to 9.7 mm, having 6.4 to 9.7 mm in men and 4.9 to 8.3 mm in women. Vertical diameter in males was higher in 59.09% of cases, with differences between 0.1 to 2.4 mm, and in 40.91% of cases the horizontal diameter was larger with differences between 0,1-2.1 mm. Vertical diameter in women was higher in 50% of cases, with differences of 0.1-2.0 mm and the other 50% the horizontal diameter was larger, with differences ranging from 0.1 to 2.2 mm. The angle that the superior mesenteric artery makes it with the aortic wall we found between 16,60-120,8o, males having values between 24,8-120,8o, and in women 16,7-120,8o. The distance between the origin of the superior mesenteric artery and celiac trunk we found it between 5.0 and 16.5 mm, males having 5.0 to 12.1 mm and women 6.9 -16.5 mm. The distance between the origin of the superior mesenteric artery and right renal artery was ranging between 6.2 to 23.5 mm, in males being 6.5 to 19.1 mm and in women from 6.2 to 23 5 mm. The distance between the origin of the superior mesenteric artery and left renal artery we found between 5.7 to 23.5 mm, in males being 5.7 to 21.2 mm, and in women from 6.2 to 23 5 mm. The distance between the aortic origin of the superior and inferior mesenteric arteries was ranging between 50.6 to 91.2 mm, in males being 50.6 to 91.2 mm and in women from 58.2 to 88.4 mm.
