To explore the influence factors for pernicious placenta previa (PPP) with placenta accreta and pregnancy outcomes of different types of PPP.A case-control study was conducted to collect 410 PPP patients admitted to a general hospital in Changsha from December 2013 to February 2018. Two hundred and fifty cases of PPP with placenta accreta were treated as a case group, and 160 cases of PPP without placenta accreta were treated as a control group. The relationship between clinical data and placenta accreta was analyzed, and the pregnancy outcomes of PPP was observed according to different types of placenta previa.Logistic regression showed that delivery times were more than 2 (OR=3.221), cesarean section times were more than 2 (OR=3.048), central placenta previa (OR=3.607), placental attachment site (anterior wall) (OR=4.592) were independent risk factors for PPP with placenta accrete (Delivery times (2), cesarean section times (≥2), central placenta previa, placenta attachment site (anterior wall) are independent risk factors for PPP with placenta accreta. Living in cities, systematic prenatal examination were protective factors. The central PPP is more likely to lead to postpartum hemorrhage, hysterectomy, and increases in the risk of preterm birth, low birth weight as well as asphyxia of fetus, which seriously threatens maternal and fetal life. |
