目的:研究凶险型前置胎盘的临床特点及处理措施。方法:回顾性分析我院2012年6月至2016年6月收治的150例凶险型前置胎盘患者(观察组)与150例普通型前置胎盘患者(对照组)的临床资料做对比。结果:凶险型前置胎盘(观察组)孕妇年龄≥35岁,流产次数≥3次,剖宫产次数≥2次的发生率明显高于普通型前置胎盘组,差异有统计学意义(P<0.01);术前B超诊断胎盘植入的敏感度为83.7%(82/98),特异度为89.8%(88/98);凶险型前置胎盘(观察组)发生胎盘植入、胎盘粘连、产后出血及输血、子宫切除的比例均明显高于普通型前置胎盘(对照组),差异有统计学意义(P<0.05)。结论:凶险型前置胎盘严重威胁产妇生命,应采取措施降低凶险型前置胎盘的发生率,规范凶险型前置胎盘的处理。
Objective: To study the clinical features and treatment of dangerous placenta previa placenta. Methods: The clinical data of 150 cases of dangerous placenta previa (observation group) and 150 cases of common type of placenta previa (control group) were retrospectively analyzed in our hospital from June 2012 to June 2016. Results: The incidence of maternal age≥35 years, abortion≥3 times and cesarean section ≥2 times in the precarious placenta previa (observation group) was significantly higher than that in the normal placenta previa (P <0.01). The sensitivity of preoperative ultrasound diagnosis of placenta accreta was 83.7% (82/98) and the specificity was 89.8% (88/98). Placenta accreta occurred in the placenta previa (observation group) The rates of adhesion, postpartum hemorrhage, transfusions and hysterectomy were all significantly higher than those of the common placenta previa (control group) (P <0.05). Conclusion: The threatening placenta previa placenta is a serious threat to maternal life, we should take measures to reduce the incidence of dangerous placenta previa and standardize the treatment of dangerous placenta previa.
