摘　　要：目的:探讨子宫颈剪切波弹性成像技术联合子宫颈超声对孕妇早产的预测价值。方法:选取2021年5月-2022年4月在苏州大学附属独墅湖医院行全程规范产前检查的孕妇129例,于孕周19^(+3)~27^(+3)周接受子宫颈弹性成像联合子宫颈超声检查,并记录孕妇的子宫颈弹性超声成像参数和子宫颈长度(CL),随访孕妇分娩结局,分为早产组和足月产组,比较两组基线资料、子宫颈弹性成像参数和子宫颈长度的差异,计算指标预测早产风险的曲线下面积、敏感度及特异度。结果:两组孕妇年龄、BMI、孕次、子宫颈手术史等基线资料比较,差异均无统计学意义(P>0.05),早产组早产史发生率高于足月产组,差异有统计学意义(P=0.03)。早产组的子宫颈内口前唇、后唇,以及外口前唇、后唇弹性值均低于足月产组,早产组的CL短于足月产组,差异均有统计学意义(t=17.27、13.48、10.77、7.47、7.05,P<0.01)。子宫颈内口前唇、后唇,以及外口前唇、后唇弹性值和CL预测孕妇早产的AUC分别为0.816、0.843、0.662、0.525、0.685。子宫颈内口前唇、后唇弹性值联合CL预测孕妇早产的AUC分别为0.852、0.887。结论:子宫颈剪切波弹性成像联合子宫颈超声能够综合反映子宫颈的弹性状态,对预测孕妇的早产风险具有临床指导价值。Objective:To explore the predictive value of cervical shear wave elastography combined with cervical ultrasound in premature delivery.Method:From May 2021 to April 2022,129 cases of pregnant women who underwent full-scale standardized prenatal examination in Dushu Lake Hospital Affiliated to Soochow University were selected to undergo cervical shear wave elastography combined with cervical ultrasonography at 19^(+3) to 27^(+3) weeks of gestation,and the parameters of cervical elastography and cervical length were recorded.The outcomes of pregnant women were followed up.They were divided into premature birth group and full-term birth group.The baseline data,parameters of cervical elastography and cervical length were compared between the two groups,the area under the curve,sensitivity and specificity of indicators were calculated to predict the risk of premature birth.Result:There were no significant differences between the two groups in terms of baseline data such as age,BMI,number of pregnancies,and cervical surgery history(P>0.05).The incidence of premature birth history in the premature birth group was higher than that in the full-term birth group,the difference was statistically significant(P=0.03).Elastic values of the anterior and posterior lips of the internal cervical opening,and the anterior and posterior lips of the external cervical opening in the premature group were lower than those of the full-term birth group,the CL of the preterm birth group was shorter than that of the full-term birth group,and the differences were statistically significant(t=17.27,13.48,10.77,7.47,7.05,P<0.01).The AUC of elastic values of the anterior and posterior lips of the internal cervical opening,the anterior and posterior lips of the external cervical opening and CL predicting premature delivery were 0.816,0.843,0.662,0.525 and 0.685,respectively.The AUC of elastic values of the anterior and posterior lips of the cervix combining with CL predicting premature delivery were 0.852 and 0.887,respectively.Conclusion:Cervical s
