[The correlation of the parameters of the circulus arteriosus cerebri and of the main cerebral arteries and their variability in circulus arteriosus anomalies].
The authors examined 414 brain preparations of males and females to study the correlation of the size of the circulus arteriosus cerebri (CAC) with the brain mass (BM) and the size of the skull, and the correlation between the area of the cross-section of the lumen (CSL) of arteries contributing to the formation of the circulus arteriosus, as well as that of the vertebral and basilar arteries with the BM. The age-specific changes of the diameters of the cerebral arteries and the variability of their parameters in CAC anomalies were studied. The CAS cross-section is larger in males than in females. The size of the CAS does not correlate with the BM. Direct correlative relations between CSL of the cerebral vessels and the BM were revealed. The diameter of the cerebral vessels is larger in males than in females. The diameter of all arteries increases from the first period of maturity to elderly age, in some arteries the process is irregular. CAC asymmetry is most marked when one of the posterior cerebral arteries arises from the internal carotid artery.
