Morphometric parameters of the ventricular system of the brain in preschool children

Objective. To establish sex and age differences in the ventricular system of the brain in preschool children.Material and Methods. We examined 36 patients aged from two to five who live in the Chernivtsi region and sought medical care in MMI “Regional Children's Clinical Hospital” in Chernivtsi during 2019-2020, of which 22 were girls and 14 were boys. The analysis of the obtained results was carried out by the package "STATISTICA 5.5" (using nonparametric methods).Results. When studying the Echo-EG indices, we detected no interhemispheric asymmetry in any case. The distance to the terminal complex on the right and left was more significant in girls than boys in almost all age categories, except for the three-year-old age, here the opposite trend was found. The analysis of M-echo by age revealed a physiological increase in the index at the age of two in boys and girls. Subsequently, the distance to M-echo gradually decreases with age in boys. In girls, this index maximally reduced at the years 3 of age. Comparison of the M-echo width by age revealed a physiological increase in the index at the age of two years in both sexes with a subsequent decrease until the age of five. In all examined children, the shape of the median complex was in the form of peaks with a narrow, clear base, with one apex. Comparison by age parameters revealed a stable value of the cerebral cortex index in all age groups. In all examined children, the “pulsation” index did not exceed 20%.Conclusions. When studying the indices: distance to the terminal complex, distance to the M-echo, the width of the M-echo, a physiological increase of this index in two-year-old children with its subsequent decrease until the age of five was revealed. CCI and pulsation index practically did not change at all ages.
