凶险性前置胎盘临床分析

Clinical analysis of pernicious placenta previa

目的:探讨凶险性前置胎盘的诊断及治疗。方法:回顾性分析我院2010-01~2015-05诊治的凶险性前置胎盘患者14例和非凶险性前置胎盘患者103例的临床资料,分析凶险性前置胎盘的危险因素及临床治疗措施。结果:凶险性前置胎盘患者的前次剖宫产与此次妊娠间隔时间明显短于非凶险性前置胎盘患者(P<0.05);孕产次、剖宫产次数、胎盘植入率、产后出血量、子宫切除率及新生儿病死率均高于非凶险性前置胎盘患者,差异具有统计学意义(P<0.05)。结论:彩色多普勒及磁共振成像(MRI)能够准确、无创、简易地诊断凶险性前置胎盘,根据诊断结果及时治疗有助于减少孕产妇死亡、产后出血、子宫切除及新生儿死亡的发生。

Objective：To investigate the diagnoses and treatment of pernicious placenta previa. Methods：Fourteen cases with pernicious placenta previa and 103 cases with non--dangerous placenta previa from January 2010 to May 2015 were retrospectively analyzed,the risk factors and clinical treatment of pernicious placenta previa were analyzed.Results： The interval between previous cesarean delivery and the pregnancy in patients with pernicious placenta previa was shorter than that of non -- dangerous placenta previa （P 〈0.05）. Gravidity, cesarean section, placenta implantation rate, postpartum bleeding, hysterectomy and fetal mortality in pernicious placenta previa were higher than those of the non--dangerous placenta previa, the differences were statistically significant（P 〈0. 05）.Conclusion： Color Doppler ultrasound and magnetic resonance imaging for the diagnosis of pernicious placenta previa have the advantages such as high accuracy, non--invasive, simple.According to the diagnostic results of pernicious placenta previa and timely treatment, can reduce maternal mortality, postpartum bleeding, hysterectomy and fetal mortality.
