目的探讨凶险型前置胎盘的病因、诊断、处理方法和预防措施。方法对31例凶险性前置胎盘与145例普通型前置胎盘的病例进行回顾性比较分析。结果两组产妇年龄、孕周、胎盘的类型无统计学意义(P>0.05)。两组病例在胎盘植入、产后出血、出血量、子宫切除、输血量有明显差异,具有统计学意义(P<0.05)。结论 凶险型前置胎盘对孕妇的危害主要是合并胎盘植入引起致命的产后大出血。对凶险型前置胎盘合并植入胎盘应在产前明确诊断,术前充分评估手术的危险及难度,术中用最有效的方法止血以减少产后大出血的发生率和保证孕产妇的生命安全,并尽量减少子宫切除。
Objective To investigate the etiology, diagnosis, treatment and prevention of dangerous placenta previa placenta. Methods 31 cases of dangerous placenta previa and 145 cases of common placenta previa were retrospectively analyzed. Results There was no significant difference in the age, gestational age and type of placenta between the two groups (P> 0.05). There were significant differences between the two groups in placenta accreta, postpartum hemorrhage, hemorrhage, hysterectomy and blood transfusion (P <0.05). Conclusion The risk of plague of placenta previa is mainly associated with fatal postpartum hemorrhage caused by placenta accreta. Placenta previa placenta accreta placenta combined diagnosis should be prenatal fully assess the preoperative risk and difficulty of surgery, surgery with the most effective way to stop bleeding to reduce the incidence of postpartum hemorrhage and ensure the safety of pregnant women, And minimize hysterectomy.
