ABSTRACT
OBJECTIVES: Planning the mode of delivery of a full-term breech singleton remains a challenging task. The aim of this work is to compare the neonatal and maternal short-term outcomes after planned vaginal delivery and caesarean section and to evaluate the influence of an MRI pelvimetry on the short-term outcomes in order to provide appropriate advice to pregnant women with breech presentation.
METHODS: This is a retrospective monocentric analysis of all deliveries with singleton pregnancies from breech presentation >36 + 0 weeks of gestation between 08/2021 and 09/2023. Short-term maternal and neonatal morbidity data were collected for intended vaginal deliveries and caesarean sections. Neonatal and maternal short-term outcomes of intended vaginal deliveries with and without MRI pelvimetry were compared.
RESULTS: In the planned vaginal delivery group, APGAR scores and arterial umbilical cord pH were significantly lower than in the planned caesarean group. The rate of asphyxia was similar in both groups. Although not significant, the rate of NICU admission was higher in the vaginal birth group (6.7 % vs. 2.7 %; p=0.27), and infants born by caesarean remained in the NICU longer (1.3 % vs. 1.8 %; p=1.0). Neonates born to women who underwent MRI prior to attempted vaginal delivery had better short-term neonatal outcomes and shorter NICU stays compared with women who did not undergo MRI, after multivariate analysis for fetal birth weight, parity, and gestational age.
CONCLUSIONS: Vaginal breech delivery is associated with lower APGAR scores and umbilical arterial pH compared with caesarean section but does not result in increased neonatal asphyxia or NICU admission. Length of stay in the NICU is shorter when a newborn is admitted after vaginal delivery. MRI pelvimetry may improve the outcome of the newborn by further selection.
