METHOD FOR PREDICTING EARLY CHRONIC CEREBRAL ISCHEMIA OF STAGES I AND II Russian patent published in 2005 - IPC

FIELD: medicine, neurology.

SUBSTANCE: one should study subpopulation composition of blood formic elements - erythrocytes and their morphodensitometric parameters - integral value of local membranous curvature, index of spicularity and erythrocytic surface area. Chronic cerebral ischemia stage I should be diagnosed at values of percentage content of discocytes ranged 60-66.2±0.8%, spherocytes - 0.7-11%, leptocytes - 0.1-2.2%, echinodiscocytes - 0.4-4.6%, stomatocytes - 5.8-2.6%, integral value of local membranous curvature being above 4.0±1.3 up to 12.5±1.5, index of spicularity being above 0.1 up to 0.15, surface area being above 24.35-26.976. The second stage should be diagnosed at values of percentage content of discocytes ranged 48-59%, echinodiscocytes - above 4.6-9.3%, discospiculocytes - 0.3-0.4%, spiculocytes - 0.8-4.2%, integral value of local membranous curvature ranged 12.5±1.5 up to 34.0±, index of spicularity being above 0.15 up to 0.3, erythrocytic surface area being above 26.976 up to 30.12. The innovation enables to objectively subdivide early stages of chronic cerebral ischemia.

EFFECT: higher accuracy of diagnostics.
