FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely neurosurgery and beam diagnostics, and can be used for selecting a surgical approach to cerebellar/tentorial cerebral infraction by performing computed tomography analysis of the brain and performing a surgical intervention. Performing a spiral computer and/or magnetic resonance tomography of the brain. Value of displacement of the medial parts of the cerebellar hemispheres is determined for the free edge of the incision of cerebellar calculus on both sides, then ultrasonic colour duplex scanning of the extra- and intracranial parts of vertebrates and basilar arteries is performed. When the hemispheres of the cerebellum are displaced from one or both sides upwards and medially beyond the free edge of the cerebellar nacrum incision to 3 mm and when the indices of peripheral resistance increase with the Purselo resistance index (RI) = 0.8–0.89 and the Gosling pulsation index (PI) = 1.8–2.49, as well as decrease in relative to standard values of diastolic speed (Vd) and preservation within standard values of systolic (Vsist) and average (TAMH) velocities of blood flow bone subtenorial decompression is performed, lateral cistern of bridge is opened, pathological subtentorial substrate is removed. If the medial parts of the cerebellum hemispheres are incised from one or two sides to depth of 3.1 to 6 mm and if peripheral resistance indices increase with RI = 0.9–0.99 and PI = 2.5–3.0, a decrease relative to standard values Vd and TAMX perform bone subtenorial decompression, open lateral cistern of bridge, remove pathological subtentorial substrate, drain side bridge cistern. If medial hemispheres of the cerebellum are scaled from one or both sides up to a depth of more than 6.1 mm and if RI = 1.0, PI is more than 3.0 and Vd = 0, bone subtenorial decompression is performed, bridge side bridge tank is opened, pathological subtentorial substrate is removed, drainage of side tank of bridge is performed, tentirootomy is made in avascular area of cerebellar labyrinth parallel to upper stony sine for not less than diameter of tentorial opening, starting incision from free edge.

EFFECT: method provides selecting a surgical approach to cerebellar tentorial cerebral infraction in subtentorial volumetric processes ensured by x-ray and ultrasonic criteria.
