【摘要】：目的探讨MR胎盘突出征预测前置胎盘患者产后出血的价值。方法回顾性分析具有完整临床资料的前置胎盘患者354例。患者于术前2周接受MR检查,评估MR胎盘突出征与产后出血的相关性。结果 354例前置胎盘患者中,孕妇的年龄(χ~2=4.34,P=0.04)、分娩时孕周(χ~2=5.19,P=0.02)及剖宫产次数(χ~2=44.85,P0.01)均与产后出血有关。MR提示胎盘突出征8例,其中6例发生产后出血。具有胎盘突出征患者和不具有胎盘突出征患者产后出血的发生率分别为75.00%(6/8)、12.72%(44/346),差异有统计学意义(χ~2=20.14,P0.01)。MRI胎盘突出征提示产后出血的敏感度、特异度、优势比(95%可信区间)及阳性似然比分别为12.00%(6/50)、99.34%(302/304)、20.59(4.03,105.23)、15.68。结论 MRI胎盘突出征预测产后出血具有重要的临床参考价值。
[Abstract]:Objective to evaluate the value of Mr placental herniation in predicting postpartum hemorrhage in placenta previa. Methods 354 patients with placenta previa were retrospectively analyzed. Results among 354 patients with placenta previa, the age of pregnant women (蠂 2 / 4.34), gestational week (蠂 2 / 2 / 5.19) and cesarean section (蠂 2 / 44.85 / P 0.01) were all associated with postpartum hemorrhage in 8 cases. The incidence of postpartum hemorrhage in the patients with placental herniation and those without placental herniation was 75.00% and 12.72%, respectively. The difference was statistically significant (蠂 ~ 2 / 20. 14 P 0.01. MRI placenta herniation indicates the sensitivity and specificity of postpartum hemorrhage. The odds ratio of 95% confidence interval) and the positive likelihood ratio of 12.00% / 50% were 99.34% and 20.594.03%, 105.23% and 15.68 respectively. Conclusion MRI placenta herniation is an important clinical reference for the prediction of postpartum hemorrhage.
