摘要：

目的　分析宫颈剪切波弹性成像定量参数联合Bishop评分对单胎妊娠孕妇早产结局的预测价值。方法　采用回顾性分析，选取2021年9月至2023年1月宝鸡市妇幼保健院收治的有早产风险孕妇116例，根据分娩结局分为早产组15例和足月组101例；足月组产妇年龄为（30.24±3.67）岁，早产组产妇年龄为（30.78±4.01）岁。采用剪切波弹性成像测量宫颈各项参数（宫颈长度、杨氏模量平均值、杨氏模量最大值），并于临产前对孕妇宫颈进行Bishop评分。采用独立样本t检验和χ²检验比较两组孕妇宫颈长度、杨氏模量平均值（Emean）（A、B、C、D点）、杨氏模量最大值（Emax）（A、B、C、D点）以及Bishop评分之间的差异，并利用受试者操作特征曲线（ROC）分析宫颈剪切波弹性成像各参数以及Bishop评分单独及联合检测对早产结局的预测价值。结果　足月组宫颈长度正常、Emean值（A、B、C、D点）、Emax值（A、B、C、D点）、Bishop评分均高于早产组（均P<0.05）。宫颈长度、Bishop评分、宫颈弹性Emean值（A、B、C、D点）、Emax值（A、B、C、D点）单独及联合预测单胎妊娠孕妇早产结局的曲线下面积（AUC）分别为0.688、0.674、0.777、0.717、0.771、0.754、0.812、0.672、0.742、0.727、0.924。结论　宫颈剪切波弹性成像定量参数联合Bishop评分可提高单胎妊娠孕妇早产结局的预测价值。

Abstract:

Objective　To analyze the value of shear wave elastography imaging quantitative parameters combined with the Bishop score in the prediction of the outcomes of preterm birth in singleton pregnant women. Methods　A total of 116 pregnant women at risk of preterm delivery treated at Baoji Maternal and Child Health Hospital from September 2021 to January 2023 were retrospectively analyzed, and were divided into a preterm delivery group (15 cases) and a term delivery group (101 cases) according to their delivery outcomes. The age of full-term mothers was (30.24 ± 3.67) years, while the age of premature mothers was (30.78 ± 4.01) years. Shear wave elastography was used to measure their cervical parameters (cervical length, mean Young's modulus, and maximum Young' s modulus), and the Bishop score on the cervix was evaluated before labor. Independent sample t test and χ² test were used to compare the differences in cervical length, mean Young's modulus (Emean) (at A, B, C, and D points), maximum Young' s modulus (Emax) (at A, B, C, and D points), and Bishop score between the two group. Receiver operating characteristic curves (ROC) were used to analyze the predictive value of each parameter of cervical shear wave elastography and Bishop score alone and their combination for preterm birth outcomes. Results　The rate of normal cervical length, Emean values (at A, B, C, and D points), and Emax values (at A, B, C, and D points) in the delivery term group were higher than those in the preterm delivery group (all P<0.05). The Bishop score in the delivery term group was higher than that in the preterm delivery group (P<0.05). The areas under the curves (AUC) of cervical length, Bishop score, Emean values (at A, B, C, and D points), Emax values (at A, B, C, and D points), and their combination for predicting the preterm birth outcomes in the singleton pregnant women were 0.688, 0.674, 0.777, 0.717, 0.771, 0.754, 0.812, 0.672, 0.742, 0.727, and 0.924, respectively. Conclusion　The combination of shear wave elastography imaging quantitative parameters and the Bishop score can improve the predictive value for the outcomes of preterm birth in singleton pregnant women.
