摘　　要：目的分析E-cervix宫颈弹性成像技术联合阴道超声预测宫颈机能不全孕妇早产的价值。方法选取2020年1—12月四川省攀枝花市妇幼保健院妇产科收治宫颈机能不全孕妇85例,均于孕20~24周接受E-cervix宫颈弹性成像联合阴道超声检查,获取孕妇的宫颈长度和宫颈组织超声弹性成像参数,并依据孕妇有无发生早产分为早产组和未早产组,比较2组的一般资料、宫颈长度(CL)和超声弹性成像参数,ROC曲线分析弹性成像联合阴道超声预测宫颈机能不全孕妇早产的价值。结果85例宫颈机能不全孕妇中,发生早产40例(47.06%);2组孕妇年龄、BMI、孕次、既往宫颈手术史等基线资料比较,差异无统计学意义(P>0.05);早产组CL短于未早产组,弹性比较指数(ECI)、宫颈外口应变率(ES)、宫颈内口应变率(IS)高于未早产组,差异均有统计学意义(t=3.527、5.259、5.001、6.103,P均<0.01);ROC结果显示,CL预测宫颈机能不全孕妇早产的曲线下面积(AUC)为0.673,宫颈组织超声弹性成像参数ECI、ES、IS预测宫颈机能不全孕妇早产的AUC分别为0.782、0.766、0.805。结论E-cervix宫颈弹性成像技术联合阴道超声可有效反馈宫颈组织弹性情况,对宫颈机能不全孕妇早产风险有一定预测价值。Objective To analyze the value of Ecervix cervical elastography technology combined with vaginal ultrasound in predicting premature delivery in pregnant women with cervical insufficiency.Methods From January to December 2020,85 cases of pregnant women with cervical insufficiency were admitted to the Department of Obstetrics and Gynecology,Maternal and Child Health Hospital of Panzhihua City,Sichuan Province.All of them underwent E cervix cervical elastography combined with vaginal ultrasound at 20-24 weeks of gestation to obtain the length of the cervix and the cervix of the pregnant women.Tissue ultrasound elastography parameters were divided into preterm group and non-premature group according to whether the pregnant women had premature delivery.The general data,cervical length(CL)and ultrasound elastography parameters of the two groups were compared,and ROC curve analysis was used to analyze the value of elastography combined with vaginal ultrasound in predicting premature delivery in pregnant women with cervical insufficiency.Results Among the 85 pregnant women with cervical insufficiency,40 cases(47.06%)occurred prematurely.There was no statistically significant difference in the baseline data of the two groups of pregnant women's age,BMI,pregnancy times,and previous cervical surgery history(P>0.05).The CL of the preterm group was shorter than that of the preterm group,the elasticity comparison index(ECI),the strain rate of the external cervical os(ES),and the strain rate of the internal cervix(IS)were higher than those of the preterm group,and the differences were statistically significant(t=3.527,5.259,5.001,6.103,all P<0.01).ROC results showed that the area under the curve(AUC)of CL predicting premature delivery in pregnant women with cervical insufficiency was 0.673,and the AUC of cervical tissue ultrasound elastography ECI,ES,and IS predicting premature delivery in pregnant women with cervical insufficiency were 0.782,0.766,and 0.805,respectively.Conclusion E cervix cervical elastography technology comb
