ВОЗРАСТНАЯ ИЗМЕНЧИВОСТЬ ВЕЛИЧИНЫ ПОКАЗАТЕЛЯ НАРУЖНОГО ДИАМЕТРА ВНУТРЕННИХ СОННЫХ АРТЕРИЙ

All organs and systems of the human body, including the vascular system, are subject to individual, sexual and age-related variability. The study of the features of the morphogenesis of the main arteries of the head at different age periods has not only theoretical, but also great practical importance for the prevention and early diagnosis of acute and chronic disorders of cerebral circulation.The aim of the work was to determine the main morphometric patterns of the structure of the internal carotid arteries of the contralateral sides, depending on the age group.Material and methods. In accordance with the purpose and objectives of the work, the outer diameter of the cerebral section of the right and left internal carotid artery was determined after the main arterial trunks had left it on the basis of the brains of 42 people aged 29-69 years, whose cause of death was not associated with pathology of the brain or blood vessels. To determine the value of the outer diameter of the ICA, photographs were taken of the base of the brain, in particular the cross section of the cerebral section of the ICA, using a Nikon 3110 reflex camera using a morphometric marker for further calculations of the absolute dimensions of the structures under study. Statistical processing of the results was carried out using the MedStat licensed computer program.Results. In the course of statistical processing of the results obtained, we found average linear positive correlations between the values of the external diameter of the right and left internal carotid arteries and the age of the subjects. It was found that age-related changes in the arterial bed did not lead to an increase in bilateral asymmetry in the external diameter of the internal carotid artery.Conclusion. Thus, with age, there is an increase in the external diameter of the internal carotid artery, which may be associated with changes in the structural organization of the arterial wall, as well as changing metabolic demands of the brain. It is possible that changes in the morphometric parameters of the great vessels supplying the brain lead to a spatial reorganization of the superficial arterial bed of the cerebral hemispheres.
