[Neuro-ultrasonography in the assessment of perinatal lesions of the brain in high-risk children at birth and at 3 months of age].

As many as 135 children belonging to the group at high risk underwent neurosonography to assess the neuropsychic status in the early neonatal period and at an age of three months. A high rate of perinatal brain injuries was established as was a close relationship between the gestation age of the child, on the one hand and the character and intensity of the injury, on the other one. It has been revealed that the combination of deep immaturity and severe ante-intranatal hypoxia predetermines almost 100% injury of the brain structures, bringing about the formation of organic pathology and impairment of the psychoneurologic development of these children by the age of 3 months.
