[摘 要] 目的:探究高清晰度血流成像(high definition flow imaging,HD⁃Flow)检测胎儿大脑中动脉(middle cerebral artery,
MCA)M1段不同位置收缩期参数对子痫前期(preeclampsia,PE)胎儿窘迫(fetal distress,FD)的预测价值。方法:选取2019年6月
—2023年6月在河北医科大学第一医院行HD⁃Flow检测的PE患者120例为研究对象,根据是否发生FD分为未发生FD(NFD)
组(n=64)和FD组(n=56),对比分析2组患者临床资料以及M1段远端和M1段近中1/3处收缩期参数。LASSO逻辑回归分析模
型筛选发生FD的潜在因素,Logistic多因素回归分析影响FD发生的危险因素。构建发生FD的风险预测模型并验证。分析各
指标对发生 FD 的预测能力。绘制受试者工作特征(receiver operating characteristic,ROC)曲线并计算曲线下面积(area under
the curve,AUC),分析不同位置收缩期参数对发生FD的预测价值。结果:LASSO回归分析筛选出15个预测因子,Logistic分析
结果显示,胎龄、宫内感染、妊娠期糖尿病、二氧化碳分压(PCO2)、M1段远端和近中1/3处的阻力指数(resistance index,RI)、搏
动指数(pulsatility index,PI)、收缩期峰值流速(peak systolic velocity,PSV)和收缩期峰值流速与舒张末期流速比值(peak systol⁃
ic velocity/end diastolic velocity,S/D)均是发生 FD 的独立危险因素。所构建预测模型 ROC 曲线验证前后的 AUC 分别为 0.801
(95%CI:0.696~0.845)和0.785(95%CI:0.688~0.829),说明模型区分度好,准确度高。胎龄、宫内感染、妊娠期糖尿病和PCO2指
标联合MCA中M1段远端和近中1/3处的收缩期参数的预测能力最优。M1段不同位置的收缩期参数有不同程度的预测价值,
其中远端 RI、近中 1/3 处 RI 和 S/D 的 AUC 分别为 0.926(95%CI:0.992~0.826)、0.904(95%CI:0.979~0.785)和 0.917(95%CI:
0.984~0.807)。结论:胎儿MCA中M1段不同位置的收缩期参数均能在一定程度上预测FD的发生,其中M1段远端RI、M1段近
中1/3处的RI和S/D的预测性能较高,构建的FD风险预测模型能较准确地预测PE患者发生FD的风险,以对其采取针对性干
预措施。

[Abstract] Objective:To explore the predictive value of high definition flow imaging(HD ⁃ Flow)in detecting different systolic
parameters of M1 segment of the fetal middle cerebral artery(MCA)for fetal distress(FD)in preeclampsia(PE). Methods:A total of
120 PE patients who underwent HD⁃Flow detection in the First Hospital of Hebei Medical University from June 2019 to June 2023
were selected as the study objects. According to the occurrence of FD,the patients were divided into the non⁃occurrence FD(NFD)
group(n=64)and the FD group(n=56). The clinical data and systolic parameters of distal M1 segment and proximal 1/3 of M1 segment
were compared between the two groups. LASSO logistic regression analysis model screened the potential factors of FD,and multivariate
logistic regression analyzed the risk factors affecting the occurrence of FD. The risk prediction model of FD occurrence was constructed
