Медико-биологические проблемы эхографические признаки возрастной инволюции сосудистой стенки позвоночных артерий

The aim of the study was to assess vascular properties of the vertebral arteries (VA) and compare them against common carotid arteries (CCA). 65 healthy voluntaries aged 20–60 years old were under study. Wall thickness, systolic and diastolic diameters of the VA and CCA were measured using ultrasonography and indexes characterizing elastic properties of theirs vascular walls (compliance, extensibility, compliance and extensibility coefficients, Peterson′s elastic modulus, beta stiffness index, Young′s modulus, lumen strain) were calculated. Wall stiffness of the VA is significantly higher than CCA (beta stiffness index for patients younger than 40 years old was 9.7 for VA and 2.8 for CCA). Wall thickness, vessel diameter and stiffness of the CCA were significantly correlated with age, however such correlations were not observed for VA. This finding is linked with the difference in the age-related remodeling processes in histologically distinct vascular walls of the compared arteries.
