%X The purpose of the study is to reveal the features of individual typological variability of macro-microscopical and biomechanical properties of the wall of intracranial part of vertebral arteries (IPVA) in adult people. Materials and methods: The research material of 228 samples of IPVA has been received by autopsy of 115 corpses of people aged 21-84 years. External diameter, thickness of the wall, diameter of lumen of artery have been measured. Biomechanical properties of IPVA have been studied by explosive carTira Test 28005 with a loading cell of 100 H. General strength (H), breaking point (H/mm2), Young s modulus (H/mm2), absolute (mm) and relative deformation (%) of samples of arteries have been defined. Results: 3 groups of variants of arteries have been isolated: with average size of a sign (M¡Ày), less than the average size (<M ¡ª y) and more than the average size (>M+ y). The conclusion: The obtained data about functional anatomy of vascular bed of brain may be useful in blood flow modeling and optimization of extra ¡ª and intravascular interventions.
