Abstract

Purpose: Immediate neonatal outcome in pregnancies complicated by placenta previa is largely dependent on gestational age. We aimed to investigate whether placenta previa increases the risk for perinatal mortality and immediate morbidity of the offspring born at term. Methods: A population-based cohort study included all singleton pregnancies, with and without placenta previa, delivered at term. Maternal and pregnancy characteristics as well as immediate neonatal morbidity and mortality were compared. Deliveries occurred between the years 1991–2013 in a tertiary medical center. Multiple pregnancies, and fetal congenital malformations were excluded. Results: During the study period 233,123 consecutive term deliveries met the inclusion criteria; 0.2 % of the babies were born to mothers diagnosed with placenta previa. Women with placenta previa were significantly older and more likely to have had a previous cesarean section. Pregnancies were more likely to be complicated with pathological presentations and cesarean hysterectomies. Babies born at term following pregnancies with placenta previa were more likely to weigh less than 2500 g (OR 2.78 CI 1.9–3.9, p < 0.001). However, 5 min Apgar score and perinatal mortality rates were comparable between the groups. Neonatal outcomes remained comparable between the groups in a sub-analysis of cesarean deliveries only. Conclusion: Although placenta previa pregnancies involve higher maternal morbidity rates, term offsprings are not at an increased risk for immediate adverse outcome.
