FIELD: medicine.
SUBSTANCE: invention refers to medicine, namely to infantile neurology. Cerebral hemodynamics is analysed in arterial and venous beds by ultrasonic dopplerography. The resistance index (RI) in anterior cerebral artery (ACA) and mean blood velocity (Vmean) in great vein of Galen are evaluated. Increase of the RI in ACA to 0.70 or higher and of the Vmean in great vein of Galen to 12 cm/sec or higher, hydrocephaly is diagnosed as progressive. The RI in ACA 0.60 and lower and the Vmean in great vein of Galen 12 cm/sec or less indicate nonprogressive hydrocephaly.
EFFECT: method extends the range of diagnostic aids for differential diagnostics of progressive and nonprogressive hydrocephaly in infants.
