Abstract

The vessels of the circle of Willis of a brain of adult persons were studied by macro-microscopic preparation computer tomography (CT-angiography). It was demonstrated that in dolichocranes, the anterior-posterior dimension of the circle of Willis was greater, than in meso- and brachicranes. Classical structure of the circle of Willis was found in humans in 38-46% of the cases studied (most frequently in dolichocranes). The vessels of the circle of Willis were characterized by a structural variability that was associated with the shape of the skull: in the individuals with meso- and brachicranial skull shape, the various deviations from the classical structure of the arteries of the circle of Willis were most common in its posterior area, while in dolichocranes these were most frequently seen in the anterior area. In 30-40% of the cases studied, there was a combination of the structural variations of the blood vessels in both anterior and posterior areas of the circle of Willis (a combined form).
