[Risk of uterine rupture after cesarean section--analysis of 1,086 births].
OBJECTIVE
In the presented paper, obstetrical management after previous caesarian section was studied in a large patient collective at the University Department of Gynaecology and Obstetrics in Cologne from 1979 to 1995. Particular attention was given to the feared complication of rupture of the uterus.


METHODS
From a total of 15,166 deliveries, 1,086 of the births had been preceded by one or more caesarian section. These 1,086 births formed the patient collective for the present study.


RESULTS
Vaginal delivery was attempted in 44.5% of patients and was successful in 86% of those cases. If there had been a previous caesarian section, the percentage shifted in favour of vaginal delivery. All patients with more than two previous caesarian sections were delivered by a primary caesarian section. The feared complication of rupture of the uterus occurred in four cases, for which case reports are presented. In view of such cases, signs of imminent uterus rupture often constitute an indication for primary (11.5%) or secondary resectioning (31.9%). No relationship was found between fetal outcome and mode of delivery.


CONCLUSIONS
This retrospective study confirms the general recommendation of vaginal delivery following previous caesarian section as long as risks are minimized by a readiness to proceed with resectioning when signs of imminent rupture of the uterus arise.
