Abstract
OBJECTIVE
The objective of this study is to investigate the effect of the mode of delivery in women with preterm breech presentation on neonatal and maternal outcome in the subsequent pregnancy.
METHODS
Nationwide population-based cohort study in the Netherlands of women with a preterm breech delivery and a subsequent delivery in the years 1999-2007. We compared planned caesarean section versus planned vaginal delivery for perinatal outcomes in both pregnancies.
RESULTS
We identified 1543 women in the study period, of whom 259 (17%) women had a planned caesarean section and 1284 (83%) women had a planned vaginal delivery in the first pregnancy. In the subsequent pregnancy, perinatal mortality was 1.1% (3/259) for women with a planned caesarean section in the first pregnancy and 0.5% (6/1284) for women with a planned vaginal delivery in the first pregnancy (aOR 1.8; 95% CI 0.31-10.1). Composite adverse neonatal outcome was 2.3% (6/259) versus 1.5% (19/1284), (aOR 1.5; 95% CI 0.55-4.2). The average risk of perinatal mortality over two pregnancies was 1.9% (10/518) for planned caesarean section and 2.0% (51/2568) for planned vaginal delivery, (OR 0.98; 95% CI 0.49-1.9).
CONCLUSION
In women with a preterm breech delivery, planned caesarean section does not reduce perinatal mortality, perinatal morbidity, or maternal morbidity rate over the course of two pregnancies.
