The authors retrospectively analysed 901 autopsy protocols of children up to 1 year in years 1986-1990. Congenital malformations were presented in 364 cases (40.4%). The most frequent anomalies were: multiple anomalies-32.7%, the cardiovascular malformations -32.1% and malformations of nervous system-22.2%. 235 (64.8%) cases of congenital malformations were presented in neonates. There was no significant difference in incidence of congenital malformations between girls and boys. The frequency of congenital anomalies in autopsy material increased from 27.5% (1976-1985) to 40.4% (1986-1990).
