Abstract
Objective To investigate the diagnosis,treatment and pregnancy outcome of pernicious placenta previa and deepen the understanding of pernicious placenta previa,offering clinical evidence for such cases.Methods Clinical data of 38 cases with pernicious placenta previa and 45 cases with placenta previa were retrospectively analyzed,including general maternal state,ultrasonic and magnetic resonance imaging ex-aminations,placental pathology and perinatal outcomes of both mother and fetus.Results The incidence of placenta accreta,hysterectomy,blood loss,postpartum hemorrhage,blood transfusion and maternal intensive care unit admissions in pernicious placenta previa group was significantly higher than those in placenta previa group (all P <0.05).The proportion of neonates with gestational age less than 36 weeks,NICU admissions, and neonatal respiratory distress syndrome in pernicious placenta previa group was higher than placenta previa group without a significant difference (all P >0.05).The incidence of maternal and perinatal morbidity be-tween pernicious placenta previa without placenta accreta and placenta previa groups did not significantly differ (P >0.05).Conclusions The incidence of placenta accrete and hysterectomy in pernicious placenta previa group was higher than that in placenta previa group.A higher risk of maternal adverse outcome was found in women with pernicious placenta previa.However,the risk of perinatal adverse outcome did not significantly in-crease.关键词
