The objective is to study morphometry of the restoration processes of the cerebral vascular bed in the progressive course of ischemic stroke. We studied the structure of the vessels and parenchyma of the brain of patients who died of ischemic stroke in the angio-neurological department of the National Hospital under the Ministry of Health of the Kyrgyz Republic. With a progressive course of ischemic stroke, brain vessel lesions are characterized by peculiar changes in the shape and contents of the vessels, different from the vessels surrounding the ischemic area, and tissues of the opposite hemisphere. The study showed that reparative processes appear early and are expressed by a change in the number of capillaries, angiogenesis and recalibration of existing vessels. With a progressive ischemic stroke, dystrophic processes prevail over the compensatory-adaptive reactions of the central nervous system, while the latter are insufficient to restore lost functions.
