Morphological characteristics of the celiac-mesenteric trunk

Abstract

The present paper describes the morphological characteristics of 12 celiac-mesenteric trunk cases highlighted by angiography-computed tomography (CT), characteristics met only in male cases (1.82% of the cases). In relation to the vertebral column, the origin of the trunk was found in the the upper half of the L1 vertebra – intervertebral disk between L1 and L2 vertebrae. At the level of its origin from the aorta, the celiac-mesenteric trunk had an external diameter with values ranging from 8.7-13.4 mm, the aortic ostium of the celiac-mesenteric had a vertical diameter ranging from 8.8 to 13.1mm, the horizontal diameter values ranging from 8.8 to 11.2mm. At the level of its origin, the celiac-mesenteric trunk and the aortic wall had an angle with values ranging from 30.0o to 90.2o. The length of the celiac-mesenteric trunk had values ranging from 21.8 to 42.5 mm, most frequently met values were ranging from 30.7 to 33.5mm. At the level of its bifurcation, the celiac-mesenteric trunk had an angle with values ranging from 82.2 to 120,7, most frequently met values were over 90o. The celiac trunk resulted from the celiac-mesenteric bifurcation had an exterior diameter of 6.2 – 10.2 mm, values that in relation to exterior diameter the celiac-mesenteric originated, it represented 65.57 – 92.47% of its external diameter. The celiac trunk up to the end of its ramification had a length with values ranging from 6.3 to 16.8 mm. In all cases being a hepatosplenic trunk, the left gastric aorta originated in the abdominal aorta in 10 cases (83,3% of the cases) and in the other 2 cases, the left gastric aorta originated in one case under the end bifurcation of the celiac trunk whereas the other case in the celiac-mesenteric trunk, before its end bifurcation. The superior mesenteric artery resulting from the ramification of the celiac-mesenteric trunk had an external diameter with values ranging from 4.4 to 8.5 mm that represented 44.44 – 85.06% of the external diameter of the celiac-mesenteric trunk.
