Predictive value of cervical length and anterior cervical angle measured by transperineal ultrasound for premature delivery after transvaginal cer-vical cerclage during pregnancy
Aim:To investigate the predictive value of cervical length(CL)and anterior cervical angle(ACA)meas-ured by transperineal ultrasound for premature delivery after transvaginal cervical cerclage during pregnancy.Methods:A total of 189 pregnant women diagnosed with cervical insufficiency and underwent transvaginal cervical cerclage in the First Affiliated Hospital of Zhengzhou University from January 2021 to June 2022 were selected,and CL and ACA were measured by transperineal ultrasound within 24 hours before cerclage operation.Logistic regression was performed with CL and ACA as independent variables and premature delivery as dependent variable to construct the combination model.ROC curve was drawn to analyze the predictive value of CL,ACA and their combination before cerclage for premature delivery.Results:A-mong the 189 cases,67(35.4%)were premature delivery.The CL of the premature delivery group was significantly lower than that of the non-premature delivery group[27.00(15.00,34.00)mm vs 32.00(28.75,36.25)mm],ACA was greater than that of the non-premature delivery group[(120.13±11.47)° vs(103.52±17.44)°](P<0.05).The AUC(95%CI)of CL,ACA,CL combined with ACA in predicting preterm delivery after cerclage were 0.679(0.596-0.762),0.792(0.727-0.856),0.813(0.749-0.877),and the AUC of ACA,and the AUC of CL combined with ACA were more than that of CL(P<0.05).Conclusion:ACA measured by transperineal ultrasound could assist CL to predict the occurrence of premature delivery after transvaginal cervical cerclage during pregnancy.
