AGE AND SEX FEATURES OF MORPHOMETRIC PARAMETERS OF THE ABDOMINAL AORTA INTERNAL ORGANS BRANCHES ACCORDING TO MULTISPIRAL COMPUTED ANGIOGRAPHY

The number of studies of the vessels of the abdominal aorta and its visceral branches using intravital imaging methods has increased significantly in recent years thanks to multislice computed tomography with contrast, which allows the most accurate determination of the size, anatomical branching options and location of the vessels. However, data from different authors differ significantly. The purpose of the study is to conduct a morphometric assessment and determine the topographic features of the vessels of the abdominal aorta based on retrospective data from multislice computed tomography in groups of adults that differ in both age and sex. The study analyzed archival multislice computed tomography angiograms of 800 men and 175 women. Data on the contingent were divided into 3 age groups, the average age for each group was: group I – 27.3±4.8 years for women and 29.6±4.7 years for men; group II – 50.2±7.1 years for women and 53.6±5.7 years for men; group III – 67.1±5.1 years for women and 66.9±4.8 years for men. Visualization of blood vessels and measurement of arterial diameter were carried out using digital computer programs of the radiologist’s measurement station «Syngo.via». As a result of the study, it was established that the diameters of the celiac trunk, left gastric artery, superior mesenteric artery, the diameter of the superior mesenteric artery at the level of 5 mm distal to the mouth of the ileocolic artery, as well as the diameters of the inferior mesenteric artery, right renal artery and aortic artery mesenteric distance had significant statistical age and sex characteristics. The angle of origin of the superior mesenteric artery had a statistically significant difference depending on sex. The diameter of the aorta increases significantly depending on age; this increase is more typical for men than for women. The data obtained as a result of the study may have reference values ​​in the clinic and complement existing knowledge on the anatomy of the abdominal vascular system.
