EP17.80: Cervical elastography and obstetric outcomes during pregnancy

We aimed to investigate whether cervical elastography during the second or third trimesters of pregnancy affects obstetric outcomes. A total of 461 singleton pregnant Korean women undergoing antenatal care at Ewha Women's University Seoul Hospital were enrolled in a prospective study from March 2022 to August 2023. Cervical elastography was measured during regular ultrasound examinations in the second and third trimesters of pregnancy, and a total of 291 women were enrolled in this study. We evaluated 5 elastographic parameters, namely, the strain of the internal os of the cervix (IOS), strain of the external os of the cervix (EOS), ratio of the strain of IOS and EOS, elasticity contrast index, and hardness ratio. ROC analysis was performed to determine whether elastographic parameters could predict labour pain. Among 291 women, 278 women had full-term delivery, and 107 participants of them had vaginal delivery. There were 39 women who had induced labour and 68 women who had give birth by labour pain. In term delivery, the ROC analysis results predicting elastographic parameters during pregnancy and spontaneous labour did not show statistically significant values. This study was conducted to determine whether cervical elastography during pregnancy is associated with obstetric outcomes. The need for follow-up analysis after enrolment of more participants may be useful to further investigate whether cervical elastography during pregnancy affects obstetric outcomes.
