[Morphologic analysis of congenital central nervous system malformations in children from the first of life dying in the years 1986-1990].
An incidence and morphology of the CNS congenital malformations in newborn babies and infants were analysed in the consecutive autopsies carried out in 1986-1990, i.e. following Tscharnobyl disaster. The obtained results were compared to those seen in the two earlier periods (1976-1980 and 1981-1986). In 1986-1990, a percentage of autopsies showing congenital CNS malformations increased approximately by two-fold (15%). The highest percentage of such malformations in specific years of the analysed period was noted in 1990 (20%). Central nervous system malformations were more frequent in female sex (57%) than in male sex (43%). In 64% of cases newborn babies were affected. A percentage of CNS malformations coexisting with other congenital malformations increased to 40% in the analysed period of time (from 29.4% in 1976-1985). Meningomyelocele (41%), congenital hydrocephalus (21.5%), multiple anomalies in brain (14%), and anencephaly (12.6%) constituted the most frequent group of CNS malformations. In 1986-1990, an incidence of meningomyelocele increased by more than two-fold (if this anomaly coexisted with hydrocephaly, an increase in the incidence exceeded three-fold), and hydrocephaly as well as an increase in the incidence of anencephaly by 1.5 times in comparison with 1976-1985.
