[Delivery after previous cesarean section].

In a four-year period (1980-1983) there were 452 women in whom one of the previous pregnancies terminated by cesarean section. Out of them, 283 (62.6%) delivered vaginally and 169 (37.4%) by repeated cesarean section. Vacuum extractor was used in 106 deliveries (23.5%). In 254 (89.8%) parturients of the examined group and in 21 (5%) parturients of the control group the manual revision of the uterus was performed. Seven incomplete and one complete silent ruptures of the uterus occurred in the examined group, the incidence being 1.8%. Six rupture of the uterus were revealed during cesarean section. Two ruptures were detected by the manual revision of the uterus. The authors are of the opinion that the manual revision of the uterus in women with previous cesarean section is necessary and that the prophylactic use of vacuum extractor is not justified.
