Abstract

To explore the maternal and perinatal outcomes for different types of placenta previa (PP). A total of 343 pregnancies with PP from January 2003 to December 2012 at our hospital were retrospectively reviewed. The general profiles, maternal and perinatal outcomes of different types of 325 singleton PP were evaluated. Among them, 221 pregnancies were of complete PP. There were partial (n = 22) and marginal (n = 82) PP. Proportions of previous vaginal and cesarean deliveries in women with complete and partial PP were higher than those with marginal PP (P < 0.05). Compared with marginal PP group, ratio of placenta in the uterus posterior wall prepartum hemorrhage and probability of blood transfusion and neonatal asphyxia were much higher in complete and partial PP. The gestational age at delivery and neonatal body weight with complete PP and partial PP marginal PP were higher than those of the other two groups (P < 0.05). As for the placenta adhesion, placenta accrete or postpartum hemorrhage, no difference existed among three groups placenta location. The gestational age at delivery, prepartum hemorrhage, probability of blood transfusion and perinatal outcome in women with PP are related with the type of PP. Both complete and partial PP have relatively worse outcomes. The type of PP has no effect on placenta adhesion, placenta accrete or postpartum hemorrhage.
