超声E-cervix弹性成像参数与妊娠期高血压孕晚期分娩方式的关系

The relationship between parameters of ultrasonic elastography using E-cervix and mode of delivery in patients with pregnancy-induced hypertension in the late trimester of pregnancy

目的分析超声E-cervix弹性成像参数与妊娠期高血压孕晚期分娩方式的关系。方法纳入进行产检的孕晚期妊娠期高血压孕产妇100例,所有孕产妇均实施超声E-cervix弹性成像参数检查,所有孕产妇均随访至最终分娩,统计所有孕产妇的分娩方式并依据分娩方式分为2组(自然分娩及剖宫产),分析超声超声E-cervix弹性成像参数对妊娠期高血压孕晚期分娩方式选择的影响。结果经随访统计,100例妊娠期高血压孕晚期孕产妇自然分娩共63例,占比63.00%;剖宫产共37例,占37.00%;自然分娩组弹性对比指数(elasticity contrast index,ECI)、宫颈外口应变(external os strain,EOS)值均大于剖宫产组,硬度比值(hardness ratio,HR)、宫颈长度(cervical length,CL)、宫颈内口应变(internal os strain,IOS)、宫颈内外口应变比值(IOS/EOS)值小于剖宫产组,差异有统计学意义(P<0.05);经点二列相关性证实,超声E-cervix弹性成像参数与妊娠期高血压孕晚期分娩方式间的关系呈正相关(P<0.05)。结论超声E-cervix弹性成像参数可评价宫颈组织变化情况,或可作为评价宫颈成熟度的半定量指标,对妊娠期高血压孕晚期分娩方式的选择具有一定的指导意义。

Objective To analyze the relationship between parameters of ultrasonic elastography using E-cervix and the mode of delivery in pregnant women with pregnancy-induced hypertension(PIH)in the late trimester of pregnancy.Methods In total,100 pregnant women with PIH in the late trimeser of pregnancy who underwent prenatal examination were included.All pregnant women were examined with ultrasonic elastography using E-cervix.All pregnant women were followed up until the final delivery.All pregnant women were divided into two groups(natural delivery and cesarean section)according to the mode of delivery,and the impact of parameters of ultrasonic elastography using E-cervix on the choice of delivery mode in pregnant women with PIH in the late trimester of pregnancy was analyzed.Results According to the follow-up statistics,63 patients(63.00%)had spontaneous delivery in 100 pregnant women with PIH in the late trimester of pregnancy,and 37 had cesarean section,accounting for 37.00%.The elasticity contrast index(ECI)and cervical external os strain(EOS)in the natural delivery group were higher than those in the cesarean section group,and the hardness ratio(HR),cervical length(CL),cervical internal os strain(IOS)and cervical internal and external os strain ratio(IOS/EOS)were lower than those in the cesarean section group,showing significant differences(P<0.05).Point-biserial correlation confirmed that there was a positive correlation between the parameters of ultrasonic elastography using E-cervix and the mode of delivery in pregnant women with PIH in the late trimester of pregnancy(P<0.05).Conclusion Parameters of ultrasonic elastography using E-cervix can be used to evaluate the changes of cervical tissue,or as a semi-quantitative indicator of cervical maturity,which has a certain guiding significance for the selection of delivery mode in pregnant women with PIH in the late trimester of pregnancy.
