Age-Specific and Sexual Variability of Morphological and Biomechanical Parameters of the Basilar Artery of Adult People

Abstract

For the purpose of studying of morphological and biomechanical parameters of the basilar artery in an experiment on monoaxonic distension by tensile-testing machine Tira Test 28005 (Germany) with a loading cell — 100 N we determined general solidity, breaking point, maximum and relative deformation of the artery. Preliminary under a microscope on cross-section cuts we measured the external diameter of the artery, its wall thickness and calculated the diameter of the lumen. In total, 114 basilar arteries (66 — from corpses of men, 48 — from corpses of women) have been investigated. They were received not later than 16 hours after autopsy of adult people, whose cause of death has not been connected with a sharp vascular cerebral pathology. The statistically authentic prevalence of the size of wall thickness and general solidity of the men’s artery wall was revealed. In age aspect the external diameter, the lumen diameter and the wall thickness of the basilar artery increase. At the same time the solidity of the wall decreases and its ability to prolongation increases.
