Abstract The aim of the work is to examine the features of recovery of lost neurological functions and the quali ty of life of patients with acute vertebrobasilar infarction, to evaluate and compare the short-term and long-term outcome of a stroke depending on the aff ected intracranial anatomical areas of the posterior circulation basin. 120 patients with acute vertebrobasilar infarction were examined, among them 22 (18.3 %) patients had a cerebral infarction, 38 (31.7 %) — pontine infarction, 13 (10.8 %) — midbrain infarction, 22 (18.3 %) — thalamic infarction and 25 (20.8 %) patients — cerebellar infarction. Strokes were distributed into three intracranial anatomical territories of the posterior circular basin: proximal, medial, distal. The diagnosis was established on the basis of data from the neurological clinic and magnetic resonance imaging in standard and DV modes. Clinical and neurological comparisons and a comparative statistical analysis of the functional outcomes of infarctions on the 21st and 90th day of a prospective observation. Despite the fact that there is no clear functional boundary between the proximal, medial and distal intracranial anatomical territories of the posterior circulation basin, which once again confi rms their functional unity, the potential for resuming lost neurological functions, a short-term and long-term outcome after infarction of diff erent anatomical and topographic areas of posterior circulation basin do not always match. Statistical analysis pointed that the short-term and long-term functional outcome after a infarction in diff erent intracranial vascular territories of the posterior circulation basin had certain features of the evolution of functional and neurological recovery. In particular, cerebellar infarctions had a signifi cantly better functional outcome compared to infarctions of the medulla oblongata in the short and long term perspective and midbrain infarctions — on the 90th day of the prospective observation (p <0.05). Paired comparisons of functional consequences between cere bellar, pontine and thalamic infarction did not reveal a statistically signifi cant (p > 0.05) correlation between factorial and eff ective signs during short-term and longterm follow-up.
