Objective:
To determine the maternal and perinatal outcome for different types of placenta previa (PP).
Methods:
A retrospective review of 132 singleton pregnancies with PP. Outcome measures, including the incidence of obstetric hysterectomy, the neonatal Apgar score, and the neonatal weight, were evaluated by logistic regression analysis.
Results:
The incidence of PP was 1.0%. Of the women with PP, 51.5% had complete PP, 20.5% had incomplete PP, 5.3% had marginal PP, and 22.7% had a low-lying placenta. Most (93.9%) women were delivered by cesarean delivery. In total, 19.7% women underwent obstetric hysterectomy; of these, 92.3% had complete PP. Mothers with 2 or more previous cesarean deliveries had an increased risk for obstetric hysterectomy (P<0.01). The gestational age at delivery was a significant linear predictor of the 5-minute Apgar score. Mothers with incomplete PP delivered neonates with lower Apgar scores than did mothers with complete PP.
Conclusion:
A history of multiple cesarean deliveries increased the risk for obstetric hysterectomy in women with PP. The type of PP had no effect on maternal and neonatal outcome, with exception of the fact that neonates in the incomplete PP group had lower Apgar scores than neonates in the complete PP group.
