摘要：
FIELD: medicine.SUBSTANCE: invention relates to medicine, namely neurosurgery and radiation diagnostics. Spiral computer and/or magnetic resonance imaging of the brain is performed. Changes at the level of the of the cerebellar tentorium cutting are defined in the axial, sagittal and frontal projections, then ultrasound color duplex scanning of vertebral and basilar arteries is performed. When the hemisphere of the cerebellum is displaced upward and medially beyond the free edge of the cerebellar tentorium cutting up to 3 mm increase in indices of peripheral resistance with resistivity index (RI) = 0.8–0.89, pulsatility index (PI) = 1.8–2.49, as well as a decrease in the relatively standard values of diastolic velocity (Vd) and preservation of the degree of cerebellar-tentorial contraction of the brain stem is considered moderate within the limits of the standard values of systolic (Vsist) and mean (TAMH) blood flow rates. When both medial parts of the cerebellar hemispheres are inclined to a depth of 6 mm the indices of peripheral resistance with RI = 0.9–0.99 and PI = 2.5–3.0, a decrease in the relative standard values of Vd and TAMX are increased, a pronounced degree of cerebellar-tentorial infringement of the brain stem is defined. When both medial parts of the cerebellar hemispheres are inclined upwards to a depth of more than 6 mm at RI = 1.0, PI more than 3.0 and Vd = 0, a significant degree of cerebellar-tentorial infringement of the brain stem is determined.EFFECT: method allows to improve reliability of the evaluation degree of cerebellar-tentorial infringement of the brain stem, which is achieved by determining the complex of investigated parameters.1 cl, 2 dwg, 3 exИзобретение относится к медицине, а именно нейрохирургии и лучевой диагностике.
