 The purpose — to evaluate the Willis circle pathology in patients with acute cerebral circulatory disorders using the National Institutes of Health Stroke Scale, to assess the degree of functional disorders and the long-term perspective.

Material and methods. Data from magnetic resonance imaging of the brain and magnetic resonance angiography of the brain were analyzed in 47 patients with acute cerebrovascular accident. The study included 21 (44,6%) men and 26 (55,4%) women, with an average age of 67,08 ± 16,03. All patients underwent neurological examination using the National Institutes of Health Stroke Scale, assessment of functional disorders using the Rivermead scale, and assessment of long-term perspective using the Rankin scale before and after treatment.

Results. Patients with the absence of one posterior connective artery showed a significant stroke severity according to the National Institutes of Health Stroke Scale. The largest subgroup with the absence of both posterior connective arteries was identified, having the best indicators on the Rivermead scale before treatment and a good recovery for neurological deficit after treatment. Significant positive results by the Rivermead scale after treatment were shown in the subgroup with the absence of all connecting arteries.

Conclusion. The variant of the Willis circle structure in the form of the absence of both posterior connective arteries in patients with acute cerebrovascular accident is most often found with a good recovery of neurological deficit.

Key words: Willis circle, acute cerebral circulation disorder, anomalies of development.
