大脑中动脉多普勒与脑胎盘比对FGR神经结局的预测
本研究为回顾性队列研究,纳入2018-2019年单胎FGR妊娠,评估大脑中动脉(MCA)多普勒及脑胎盘比(CPR)对新生儿神经和呼吸结局的预测效能。结果显示MCA(OR 0.51,95%CI 0.32-0.82)和CPR(OR 1.36,95%CI 1.10-1.68)是神经结局的显著预测因子(p<0.05),多变量模型AUC达80.30%。
要点
- MCA多普勒和CPR可预测FGR胎儿不良神经结局。
- 多变量模型预测神经结局的AUC为80.30%。
- 新生儿头围与MCA PI z-score的相关性仅见于单变量分析。
核心结论
- MCA多普勒和CPR是FGR胎儿不良神经结局的有效预测因子,可能有助于临床风险分层。
研究设计与样本
- 回顾性队列研究,纳入2018-2019年单胎FGR妊娠,收集MCA和CPR多普勒指数(z-score)及新生儿神经和呼吸结局。
主要发现
- MCA(OR 0.51,95%CI 0.32-0.82)和CPR(OR 1.36,95%CI 1.10-1.68)是神经结局的显著预测因子(p<0.05)。
- 孕龄和CPR的单变量准确性相当,但多变量模型表现更优,AUC为80.30%。
- 单变量分析显示新生儿头围与MCA PI z-score显著相关,但多变量分析未证实。
临床怎么用
- 临床可考虑使用MCA多普勒和CPR对FGR胎儿进行神经结局风险分层。

OBJECTIVE: To assess the efficacy of middle cerebral artery (MCA) Doppler ultrasonography in predicting neurological and respiratory outcomes in fetuses with fetal growth restriction (FGR) and to establish a correlation between MCA Doppler and head circumference (HC). METHOD: Retrospective cohort study examining singleton pregnancies affected by FGR (2018-2019). MCA and Cerebroplacental Ratio (CPR) Doppler indices (z-scores) alongside neonatal neurological and respiratory outcomes were gathered. RESULTS: MCA (OR 0.51, 95% CI 0.32-0.82) and CPR (OR 1.36, 95% CI 1.10-1.68) were identified as significant predictors of neurological outcomes (p < 0.05). Gestational age and CPR exhibited comparable univariate accuracy; however, the multivariate model demonstrated superior performance, achieving an area under the curve of 80.30%. Correlation analysis indicated a significant relationship between neonatal HC and MCA PI z-score in univariate analysis, but this was not confirmed in multivariate analysis. CONCLUSION: MCA Doppler and CPR are effective predictors of adverse neurological outcomes in FGR, potentially aiding risk stratification in clinical practice.
