Abstract Objective: To analyze pregnancy outcomes of women with pernicious placenta previa and placenta accrete. Methods: The clinical data of 92 women with pernicious placenta previa and placenta accreta were analyzed and were stratified analyzed. Results: The average blood loss of these women was 300-11000 ml, 15 (16.3%) women had received hysterectom， and 21(22.8%) women had perinatal complications. There were 90 (97.8%) live births, and 41 (45.5%) newborns had been transferred to NICU. Blood loss of women with placenta accreta diagnosed by ultrasonography, women with placenta accreta diagnosed after cesarean, or women with placenta hole punching during cesarean had increased significantly (P<0.05). The incidence of hysterectomy of women with 4-9 times of pregnancy was significant higher than that of women with 1-3 times of pregnancy (P<0.05). The incidences of hysterectomy and perinatal complicationsan of women with placenta accreta diagnosed by ultrasonography and women with placenta accreta diagnosed after cesarean had increased significantly (P<0.05), but those of women received comprehensive management during pregnancy had decreased significantly (P<0.05). There was no statistically significant different in the incidence of newborns transferred to NICU among women with different situation (P>0.05). Conclusion: The women with pregnancy over 3 times, with cesarean history, with placenta accreta diagnosed by ultrasound, or with postoperative diagnosis of placenta accreta have worse pregnancy outcomes. The women accepting comprehensive management during pregnancy have lower hysterectomy.
