中文摘要:
      [摘要] 目的 探讨妊娠中期胎盘完全性前置状态孕妇妊娠晚期胎盘迁移情况及其影响因素。 方法 回顾性分析2017年1月至2020年1月于长沙市第四医院妊娠中期检查发现胎盘完全性前置状态并进行常规产检分娩的104例单胎孕妇的临床资料。根据妊娠晚期产检B超观察结果分为胎盘迁移组(n=90)与胎盘未迁移组(n=14),通过logistic回归分析影响胎盘迁移的相关因素。 结果 妊娠中期胎盘完全性前置状态孕妇在妊娠晚期至分娩时胎盘迁移正常位置的发生率为86.54%。单因素分析显示,胎盘附着宫壁位置、胎盘粘连情况是妊娠晚期胎盘迁移结局的影响因素,logistic回归分析显示胎盘附着宫壁位置、胎盘粘连情况是胎盘迁移结局的独立危险因素(P < 0.05)。 结论 胎盘附着宫壁位置、胎盘粘连情况是妊娠中期胎盘完全性前置状态孕妇在妊娠晚期未迁移正常位置的独立危险因素。
英文摘要:
      [Abstract] Objective To investigate the placental migration in the third trimester of pregnancy and its influencing factors for pregnant women with complete placenta previa in the second trimester of pregnancy. Methods The clinical data of 104 singleton pregnant women who were diagnosed to have complete placenta previa in the second trimester of pregnancy, and received routine birth examination and delivered babies in the Fourth Hospital of Changsha from January 2017 to January 2020 were retrospectively analyzed. According to the observation results with B-mode ultrasound in the third trimester of pregnancy, they were divided into the placenta migration group (n=90) and the no placenta migration group (n=14). The related factors affecting placenta migration were analyzed by logistic regression. Results The incidence of placental migration to normal position from the third trimester of pregnancy to delivery was 86.54% in pregnant women with complete placenta previa in the second trimester of pregnancy. Univariate analysis showed that placental attachment to the uterine wall and placental adhesion were influencing factors for the outcome of placental migration in late pregnancy and delivery. Logistic regression analysis showed that placental attachment to the uterine wall and placental adhesion were independent risk factors for the outcome of placental migration (P < 0.05). Conclusion Placental attachment to the uterine wall and placental adhesion are independent risk factors for no placental migration to normal position in the third trimester of pregnancy in pregnant women with complete placenta previa in the second trimester of pregnancy.
