Abstract

Although perinatal diagnosis and management has been developed rapidly in recent years, congeni- tal malformations are known to have remained largely unchanged in incidence of infants being delivered. In spite of its clinical significance and physician’s every effort to exclude the possible factors of congenital malformations by perinatal care, there is still no enough statistical data of congenital malformtions in Korea. So, we surveyed to know the incidence of congenital malformations at Hanyang University by utilizing hospital records of birth. During the period of 12 7/12 years, from May 1 1972 untl Dec. 31,1984 21,526 deliveries at Hanyang University Hospital were statistically observed on the basis of neonatal records and delivery notes. The results were as follows: 1) The incidence of congenital malformations among 21,526 deliveries was 0.76% (0.76% among live birth and 3.27% among still births). 2) Sex distribution (male to female) among malformed babies was 53:43 and sex undetermined case was about 4%. 3) Among 177 malformed babies, 30 (16.9%) babies had more than one malformations. Haring two congenital malformations was more frequent (57%). 4) Among 20 malformations, 63 malformations (28.6%) were in the central nervous system, 49 (22. 3%) in the gastrointestinal tract, 43 (19.6%) in the musculoskeletal system, 26 (11.8%) in the skin. 5) The congenital malformations observed in the neonatal death and stillbirths were anencephaly (66.1%), hydrocephaly (13.5%), meningomyelocele (8.5%), polydactyly, cleft palate, omphalocele, in order of frequency. 6) Among 220 malformed babies, 129 babies (58.6%) had major malformations and 105 babies (45. 3%) had minor malformaitons.
