Transvaginal three-dimensional energy Doppler ultrasonography combined with transabdominal ultrasonography in the diagnosis of scar pregnancy classification after cesarean section
Objective:To investigate the accuracy of transvaginal three-dimensional energy Doppler ultrasonography plus transabdominal ultrasonography in classification of scar pregnancy(Cesarean scar pregnancy,CSP)after cesarean section.Methods:The clinical data of 78 patients with CSP admitted to our hospital from January 2022 to August 2023 were retrospectively collected.After admission,all patients underwent transvaginal three-dimensional energy Doppler ultrasound and transabdominal ultrasound.The results of clinical surgery were used as the gold standard for classification.The consistency and accuracy of transvaginal three-dimensional energy Doppler ultrasound,transabdominal ultrasound and their combined diagnosis of CSP were compared.Results:Among the CSP patients,22 cases were type I,37 cases were type II and 19 cases were type III.The results of CSP classification by transabdominal ultrasound were consistent with clinical results(Kappa=0.696,P<0.05).The results of transvaginal three-dimensional energy Doppler ultrasound diagnosis of CSP were consistent with clinical results(Kappa=0.759,P<0.05).The results of the combined diagnosis of CSP were consistent with the clinical results(Kappa=0.919,P<0.05).The accuracy of CSP classification by the combined examination was higher than that by abdominal ultrasound and transvaginal three-dimensional energy Doppler ultrasound alone,and the differences were statistically significant(P<0.05).Conclusion:Compared to standalone transabdominal ultrasound and transvaginal three-dimensional energy Doppler ultrasound,the combination examination has stronger consistency and higher accuracy in diagnosing CSP classification.
