Analysis of maternal and neonatal outcomes in different types of placenta previa and in previa-accreta coexistence

Abstract

AimIt was aimed to compare the maternal and neonatal outcomes be-tween different types of placenta previa (PP) and previa-accreta.MethodThis retrospective case-control study included 213 singleton pregnancies diagnosed with PP using the antenatal ultrasonographic exami-nation in a tertiary reference hospital between January 2014 and December 2015. The patients were categorized into 5 groups: 1-low-lying, 2-marginal, 3-partial, 4-complete, and 5-coexistence of PP and placenta accreta (previa-accreta).ResultsMean gravida, parity, and number of previous caesarean sections (CS) were significantly higher in the previa-accreta group. Com-pared to other groups, significantly lower postoperative haemoglobine level and longer hospital stay was determined in the previa-accreta group. In the complete PP and previa-accreta groups, the mean blood loss, the rate of admission to intensive care unit (ICU), and the rate of hysterectomy were significantly higher. The rate of preterm birth was significantly higher in the previa-accreta group than the other groups. The groups were similar with respect to mean gestational week at birth and birthweight. In the comparison of complete PP cases with the non-complete PP (low-lying, marginal and par-tial PP), the need for blood products transfusion, the risk of placenta accreta, peripartum hysterectomy, postpartum haemorrhage, and follow-up in the ICU were increased in the complete PP group.ConclusionThe coexistence of placenta previa-accreta increases maternal-neonatal morbidity. Compared to cases with complete PP; low-lying, marginal, and partial PP do not result in an increase in maternal-neonatal morbidity.
