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.
作者检查了414份男性和女性的脑标本，以研究大脑动脉环（CAC）大小与脑质量（BM）和颅骨大小之间的相关性，以及参与大脑动脉环形成的动脉管腔横截面面积（CSL）与椎动脉和基底动脉的CSL与BM之间的相关性。研究了脑动脉直径的年龄特异性变化及其在CAC异常中的参数变异性。男性的CAS横截面比女性大。CAS的大小与BM无关。揭示了脑血管CSL与BM之间的直接相关关系。男性脑血管直径大于女性。所有动脉的直径从成熟期到老年期都增加，在一些动脉中这个过程是不规则的。当大脑后动脉之一起源于颈内动脉时，CAC不对称最为明显。
