摘　　要：目的探讨子宫动脉及髂内动脉彩色多普勒超声参数在孕中期不良妊娠结局预测中的应用价值。方法回顾性收集2020年1月至2023年1月期间70例于我院接受产检并分娩的孕妇的临床资料,根据2组妊娠结局分为良好组与不良组,其中良好组48例,不良组22例。比较2组子宫动脉以及髂内动脉彩色多普勒超声血流参数水平;分析孕中期子宫动脉以及髂内动脉彩色多普勒超声血流参数水平对不良妊娠结局的预测价值。结果良好组子宫动脉搏动指数(PI)、阻力指数(RI)、收缩期与舒张期峰值血流速度比值(S/D)以及髂内动脉S/D、血流加速时间(AT)均低于不良组(P<0.05)。经logistic多因素回归分析显示,子宫动脉PI、RI、S/D以及髂内动脉S/D、AT值升高均为可能导致不良妊娠结局的危险因素(P<0.05);ROC曲线分析显示,子宫动脉PI、RI、S/D以及髂内动脉S/D、AT预测不良妊娠结局的灵敏度分别为86.4%、72.7%、81.8%、63.6%、77.3%;而5项参数联合预测不良妊娠结局的灵敏度为90.9%,高于单项参数预测灵敏度(P<0.05)。结论孕中期子宫动脉PI、RI、S/D以及髂内动脉S/D、AT值异常升高为不良妊娠结局的危险因素,通过对其进行联合监测有利于提高对不良妊娠结局的预测价值。Objective To explore the application value of color Doppler ultrasound parameters of uterine artery and internal iliac artery in predicting adverse pregnancy outcomes during mid pregnancy.Methods Clinical data of 70 pregnant women who underwent prenatal examination and delivery in our hospital from January 2020 to January 2023 were retrospectively collected.According to the pregnancy outcomes of the two groups,they were divided into a good group and an adverse group,with 48 cases in the good group and 22 cases in the adverse group.Compare the blood flow parameters of uterine artery and iliac artery in two groups using color Doppler ultrasound;Analyze the predictive value of color Doppler ultrasound blood flow parameter levels of uterine artery and iliac artery in mid pregnancy for adverse pregnancy outcomes.Results The results showed that the uterine artery pulsatility index(PI),resistance index(RI),peak systolic to diastolic blood flow velocity ratio(S/D),internal iliac artery S/D,and blood flow acceleration time(AT)in the good group were lower than those in the poor group(P<0.05).Logistic multivariate regression analysis showed that elevated uterine artery PI,RI,S/D,and internal iliac artery S/D,AT values were all potential risk factors for adverse pregnancy outcomes(P<0.05);Receiver operating characteristic analysis showed that the sensitivity of PI,RI,S/D of uterine artery and S/D,AT of internal iliac artery in predicting adverse pregnancy outcomes were 86.4%,72.7%,81.8%,63.6%and 77.3%,respectively;The sensitivity of the combination of five parameters in predicting adverse pregnancy outcomes was 90.9%,which was higher than the sensitivity of single parameter prediction(P<0.05).Conclusion Abnormal increases in PI,RI,S/D,and S/D,AT values of the uterine arteries in the second trimester of pregnancy are risk factors for adverse pregnancy outcomes.Combined monitoring of these values can improve the predictive value of adverse pregnancy outcomes.
