Kim, S J; Kim, S P

Abstract

We have observed 32 cases of lethal anomalies by antenatal ultrasonogram, based on the 108 cases of major congenital anomalies among 6757 newborns delivered from Jan. 1, 1993 to Dec. 31, 1995 at department of Obstetrics and Gynecology, Holy Family Hospital of Catholic University. The analysed results were as follows: 1. The incidence of the lethal anomalies were 32 cases among 108 congenital anomalies (29.62%), 6757 newborns (0.47%). 2. The incidence of the lethal anomalies over 35 and under 20 years old was absent. 3. The incidence of the lethal anomalies according to parity was not significant in the multipara groups and nullipara groups. 4. The frequency of the lethal anomalies in female baby (0.56%) was higher than that of male baby (0.39%). 5. Each incidence of the termination of the lethal anomalies less than 28 weeks gestation and 1000 gm was 93.72%, 84.7% respectively. 6. The incidence of the lethal anomalies were 46.87% in central nervous system, 21.87% in genitourinary system, 9.37% in musculoskeletal & skin, and 6.25% in cardiopulmonary system. The most single anomaly among the lethal anomalies was anencephaly (34.37%). 7. The incidence of selective autopsy among the lethal anomalies was 17cases (53.12%).
