Abstract

The aim of the study was to evaluate morphology of the terminal part of the abdominal aorta in different periods of human life. Two hundred and twelve human bodies, aged from the 7 gestational months to 82 years, were examined. Transversal diameters of the abdominal aorta and subaortal angle were measured. In males the dimension of the terminal part of aorta – just over the origin of common iliac arteries – increased from 3.63 mm in 7th  month of prenatal period to 21.56 mm in the 50-59 age group. The female values were lower and set as 3.0 and 21 mm, respectively. The dimension on the level of the bifurcation increased from 4.80 to 29.16 mm in males, and 4.35 to 27.03 mm in females. However, the subaortic angle was higher in females. It ranged from 58.5° in the age group 1-4 years to 93° in the old ones. In males, in corresponding periods of life, the angle reached 54.7 and 74.1°. In the group over 50, the common iliac arteries departed at a small angle and then they went sideward unilaterally or bilaterally. In the groups aged 50-59, 60-69 and older, such cases were found in 50, 60 and 50% - in males, and 10, 20 and 50% in females, respectively.
