[Results of conservative and surgical treatment for placenta praevia (author's transl)].

Modified cervix cerclage was applied to 75 women with placenta praevia, between the 16th and 36th weeks of pregnancy. Results obtained from conservative treatment of patients for placenta praevia are compared with those obtained from surgical treatment. Pregnancy was extended 38.4 days on average by cervix cerclage. Complaints were removed by surgery from 50.6 per cent of the patients who were dismissed from hospital. They showed neither bleeding nor any sings of imminent premature birth. Perinatal mortality went down to 6.45 per cent. Average extension of pregnancy by conservative treatment was 12.8 days. Only 7.3 per cent of the patients could be dismissed from hospital. Perinatal mortality went up to the order of 19.1 per cent. These data are interpreted as providing evidence to the advantage of surgical treatment of placenta praevia, as perinatal mortality is reduced.
