Aim. Research - to reveal regularities of dimensional characteristics of arteries of the brain of people at advanced age. Material and Methods. Investigated samples of anterior cerebral artery (ACA), middle cerebral artery (MCA), posterior cerebral artery (PCA), posterior communicating artery (PComA), basilar artery (BA) and intracranial parts of the vertebral arteries (VA) withdrawn at autopsy of 21 corpses of people of advanced age. Death hasn’t been connected with sharp vascular pathology of a brain. Studied the outer diameter, wall thickness, diameter of a gleam of arteries. For assessment of the importance of distinctions used Student’s t-criterion for independent selections (distribution normal). Results and Discussion. The sizes of arteries of a brain at adults of advanced age have no significant bilateral and sexual distinctions and are characterized by average variability (the coefficient of variability 11-25%). Averages the outer diameter, thickness of a wall and diameter of a gleam of the studied arteries (mm): ACA - 2.28±0.05, 0.27±0.01 and 1.74±0.05; MCA - 2.99±0.05, 0.31±0.01 and 2.37±0.05; PCA - 1.36±0.04, 0.24±0.01 and 0.87±0.04; PComA - 2.34±0.06, 0.27±0.01 and 1.79±0.06; BA - 3.45±0.13, 0.41±0.03 and 2.65±0.11; VA - 3.02±0.11, 0.33±0.01 and 2.36±0.09. Differences between the parameters of arteries of the same name are statistically not significant: for the outer diameter of MCA and VA; for thickness of a wall of ACA and PCA, MCA and VA, ACA and PComA, PComA and PCA; for diameter of a gleam of MCA and VAS, VA and BA.
