The purpose - to tap features of individual, age-specific, sexual and bilateral variability morphometric characteristics posterior communicating arteries of adult people. Material and methods. As a research material 115 corpses of people received at autopsy (79 men and 36 women) at the age from 21 till 84 years have served posterior communicating arteries. Measured length of artery, under a microscope studied external diameter, a thickness of wall and diameter of lumen. For the analysis of age variability the research material has been distributed for 4 age periods - the first and second periods of mature age, elderly and senile. Results. By the expressed sexual dimorphism were characterized: length and the thickness of wall posterior communicating arteries prevailing at men, and diameter of a lumen prevailing at women. Significant bilateral differences are inherent only to length posterior communicating arteries. With the years the length and diameter of lumen posterior communicating arteries practically did not change. The external diameter of artery identical throughout all mature and advanced age, to senile age it was statistically significantly enlarged on the average by 5,1 % (р=0,017). The thickness of wall posterior communicating arteries identical throughout all mature age, to advanced age was statistically authentically enlarged on the average by 14,3 % (р=0,001), and then on 12,5 % to senile age (р=0,001). Сonclusion. The obtained data will allow to order available numerous data on dimensional characteristics of arteries that matters for the best understanding of investigated area  neuromorphology, and can be useful at blood flow modelling in arterial circle of brain.
