摘要 目的评价子宫动脉舒张早期切迹指数(NI)对异常妊娠结局的预测价值。方法产前检查时用多普勒监测239位高危单胎孕妇左侧子宫动脉NI值,并随访至产后,根据妊娠结局分为正常和异常结局组。根据NI值和妊娠结局作ROC曲线,选出灵敏度和特异度均较高的数值,作为该参数的预测界值,评价其预测价值。结果子宫动脉NI值随孕周增加而升高。妊娠结局异常者其NI值较正常者高。根据ROC曲线可确定NI的正常范围分别为:11～14+6周,NI>0.805;20～24+6周,NI>0.905;29～34+6周,NI>0.961。其对异常妊娠结局的阴性预测值分别为78.0%,82.5%,84.6%;阳性预测值分别为58.3%,61.5%,56.5%。结论NI对妊娠结局有较好的预测价值。
