目的:探讨产妇发生胎盘植入的相关危险因素,为有效控制及减少胎盘植入的发生提供依据。方法:回顾分析124例胎盘植入产妇的临床资料,分析引起胎盘植入的相关危险因素。结果:胎盘植入的发生率为0.19%(124/66000),其中粘连性胎盘植入占7.26%(9/124),植入性胎盘植入占73.39%(91/124),穿透性胎盘植入占19.35%(24/124)。单因素分析结果显示,孕妇年龄≥30岁、孕前BMI≥24kg/m2、流产史、孕次≥2次、宫腔操作史、前置胎盘、疤痕子宫、早孕期阴道出血史是胎盘植入发生的危险因素(P<0.05或P<0.01)。多因素Logistic回归分析显示,合并有前置胎盘、疤痕子宫、早孕期阴道出血史是引起胎盘植入的独立危险因素(P<0.01)。结论:应对前置胎盘、疤痕子宫、早孕期阴道出血史的孕妇进行干预,以降低胎盘植入的发生。
Objective: To investigate the related risk factors of placenta accreta in maternal and provide the basis for the effective control and reduction of placenta accreta. Methods: A retrospective analysis of 124 cases of placenta accreta in maternal clinical data, analysis of the placenta accreta associated risk factors. Results: The incidence of placenta accreta was 0.19% (124/66000), of which adhesive placenta accreta accounted for 7.26% (9/124), implanted placenta accreta accounted for 73.39% (91/124), penetrability Placenta accreta accounted for 19.35% (24/124). Univariate analysis showed that the history of placenta accreta occurred when the age of pregnant women was ≥30 years old, BMI≥24kg / m2 before pregnancy, miscarriage history, ≥2 times of pregnancy, intrauterine operation history, placenta previa, scar uterus and vaginal bleeding in early pregnancy Risk factors (P <0.05 or P <0.01). Multivariate Logistic regression analysis showed that the history of vaginal bleeding complicated with placenta previa, uterine scar and early pregnancy was an independent risk factor for placenta accreta (P <0.01). Conclusion: Pregnant women with history of placenta previa, scar uterus and vaginal bleeding in early pregnancy should be intervened to reduce the incidence of placenta accreta.
