Aim. Compare the diameters of the suprarenal and infrarenal parts of the human abdominal aorta. Material and Methods. By the method of computational anatomy «Anatomia in silico» three-dimensional models of the vascular bed of the abdominal cavity and retroperitoneal space were constructed on the basis of multispiral computed tomography. 56 men and 36 women aged 21 to 86 years who did not have a history of kidney disease and kidney vessels. Results and Discussion. In the course of our work, we found sex and age differences. In men, the diameter of the abdominal aorta averaged 19.74±3.67 mm, and in women 17.02±2.9 mm. The minimum diameter of the abdominal aorta in men was 14.07 mm, and in women 9.89 mm. Changes in the diameters of the abdominal aorta at the level of the renal artery divergence are associated with age-related changes in the elasticity of the abdominal aorta wall and significantly increase in both men and women. Moreover, the increase in diameter in women occurs smoothly during adulthood (from 15.7 to 16.25 mm) and during the elderly and senile age (from 18.29 to 18.76 mm). In men, the diameter oscillations are more pronounced in adulthood (from 16.71 to 19.03 mm), and in the transition from the elderly to the senile (from 20.07 to 23.74 mm). Conclusions. The change in the diameter of the abdominal aorta can become an important circumstance that affects blood circulation inside the kidney and, as a consequence, can cause arterial hypertension.
