| Abstract |
|
Congenital malformations are still one of the leading problems of neonatal death and illness. But,
we have only a few data for about it, because of difficulty in the exact analysis of the incidence and
etiologic factors.
During the period of 6 years, between January 1980 and December 1985, a clinical study about the
general incidence of congenital malformations was done on 50, 979 live borns delivered at 7 hospitals
of Catholic Medical Center.
The results were as follows:
1) The incidence of congenital malformations was 2.1% and the frequency of male congenital
malformations was 2.3% and that of females was 1.8%.
2) The incidence of malformations in low birth weight infants (4.0%) was higher than that of
normal (1.9%) and high birth weight infants (1.6%).
3) In the prematures below 37 weeks, malformations occured more frequently than in the mature
infants above 37 weeks (4.5% vs 1.9%).
4) The incidence of malformations was 2.0% and 2.8% in below and above 35 years of maternal age
groups, respectably.
5) Among 1,050 malformed infants, 277 (26.4%) had more than one malformation.
6) Gastrointestinal system was the most frequently involved system (24.4%) and then musculo-
skeletal system, skin, cardiovascular system in the order.
7) The most frequently involved system which caused the neonatal death was central nervous
system (39.8% of 191 total death).
8) Major congenital malformations were 64.8% and minor malformations were 35.2%. |
