摘　　要：目的:探讨经阴道超声检测的宫颈定量指标与分娩方式的相关性研究。方法:收集2020年9月—2021年11月于秦皇岛市第一医院进行产前超声检查的初产妇101例,经阴道超声测量宫颈长度,启动弹性成像检查模式,分别检测宫颈前后壁的弹性值,分析评价上述宫颈指标与分娩方式的相关性。结果:101例产妇经阴道分娩46例,剖宫产55例。宫颈长度、宫颈前上部弹性值与分娩方式具有统计学意义(P<0.05),宫颈后上部、前中部、后中部、前下部以及后下部的弹性值与分娩方式无统计学意义(P>0.05);宫颈长度、宫颈前上部弹性值与分娩方式均呈正相关(r=0.492,0.579,P<0.05),说明宫颈越短,宫颈前上部弹性值越低,顺产的可能性越大;以3.35 cm为阈值,宫颈长度预测初产妇剖宫产的敏感性和特异性分别为61.8%、85.1%;以8.85 kPa为阈值,宫颈前上部弹性值预测初产妇剖宫产的敏感性和特异性分别为74.5%、85.1%,二者联合预测初产妇剖宫产的敏感性和特异性分别为74.5%、89.4%。结论:经阴道超声检测宫颈长度以及宫颈前上部弹性值可为预测初产妇分娩方式提供量化数据参考。Objective:To determine the correlation between quantitative cervical parameters and delivery mode using transvaginal ultrasonography.Methods:A total of 101 primiparas were collected using transvaginal ultrasonography between September 2020 and November 2021 at the First Hospital of Qinhuangdao.The cervical length was measured using transvaginal ultrasonography.The elastography mode was initiated to detect the elastic values of the anterior and posterior parts to evaluate the correlation between the above cervical parameters and the delivery mode.Results:There were 101 cases,including 46 spontaneous deliveries and 55 cesarean deliveries.The cervical length,elasticity of the anterior upper cervix,and delivery mode were statistically significant(P<0.05).Elasticity in other parts of the cervix and delivery mode were not statistically significant(P>0.05).Cervical length and elasticity of the anterior upper cervix were positively correlated with delivery mode(r=0.492,0.579,P<0.05).This indicated that the shorter the cervix and the lower the elasticity value of the anterior upper cervix,the greater the possibility of transvaginal delivery.Using 3.35 cm as the threshold,the sensitivity and specificity of cervical length for predicting cesarean section were 61.8%and 85.1%,respectively.Using 8.85 kPa as the threshold,the sensitivity and specificity of the elasticity of the anterior upper cervical region for predicting cesarean section were 74.5%and 85.1%,respectively.The sensitivity and specificity of combination therapy were 74.5%and 89.4%,respectively.Conclusion:Cervical length and elasticity of the anterior upper cervix measured using transvaginal ultrasonography can provide quantitative data reference for predicting the delivery mode in primiparous women.
