The severe outcomes of pregnancies with pernicious placenta previa after the first cesarean delivery
In this study, the clinical consequences such as hysterectomy, severe bleeding during delivery and massive postpartum hemorrhage (≥1000ml), and placental implantation, were defined as severe outcomes. Our result showed that the gestation of pregnancies was 30-39+5weeks. As shown in Fig. 1, the hysterectomy was conducted in 78 cases with hysterectomy rate of 10.4%. The uterine rupture rate was 0.8%. The placenta implantation was confirmed from 355 women during operation with incidence rate of 47.5%. Meanwhile, 55.8% of pregnancies had massive hemorrhage. The blood transfusion was given to 64% of pregnancies. No maternal or fetal mortality was reported.
