The purpose of the article is to define variants of anterior cerebral artery (АСА) of adults depending on typological and combined variability of its morphological and biomechanical features. Material and methods: The research has included 228 samples of anterior cerebral arteries, 115 corpses of people aged 21-84 years received on autopsy. The following points have been under the research: external and internal diameters, wall thickness, general strength, strength range, absolute and relative deformation of an artery. Results: According to the studied parameters 3 groups of variants of arteries have been allocated: with average size of a sign (M±s), with lesser size of a sign ( M + s). Combined variability of morphological and biomechanical features of АСА has been presented. Conclusion: АСА groups with higher variability, especially at men, have been observed in 2,2-2,6 times more often, than at women. As exception, thin-walled АСА which in 1,7 times more often taped at women have been considered. It has been revealed that subjects of alternative group III in 1,2-1,7 times older than those of alternative group I of arteries. Age of subjects who have been classified according to biomechanical parameters of АСА wall has been approximately identical (r=0,28-0,51). The experimentally received data about morphological, deforming and strengthening features may be of great value in studying of blood flow modeling and in optimization of intravascular interventions on cerebral arteries.
