Clinical analysis of 128 cases of pernicious placenta previa.
Abstract： Objective To investigate the clinical characteristics of pernicious placenta previa during pregnancy，and to improve the understanding of pernicious placenta previa and accumulate clinical management experience.Methods A retrospective analysis was done in 128 cases of pernicious placenta previa (observation group)and 384 cases of normal placenta previa (control group) in Shengjing Hospital affiliated to China Medical University from August 2009 to August 2014.Results In the observation group,the incidence of placental adherence（22.6%），placenta accreta（44.5%），hysterectomy（20.3%），and transfusion of postpartum hemorrhage（42.2%） were apparently higher those that of control group，the difference being statistically significant (P<0.05).Comparison of two groups on neonatal outcome showed statistical significance (P<0.05) in premature infants.Conclusion Pernicious placenta previa seriously threatens maternal and fetal life.Strictly grasping the indications for cesarean section and reducing the rate of cesarean section is the key to reducing the number of pernicious placenta previa.
