Abstract

Background: Cervical length can be measured transvaginally to help determine whether vaginal delivery will occur within 24 hours following induction. The objective of the current study is to investigate the accuracy of transvaginal ultrasound measurement of cervical length as a prediction of the time needed for a medically assisted pregnancy termination in the second trimester that occurs within 24 hours.
Patients and methods: In a case series at Ain Shams University Maternity Hospital, Transvaginal ultrasonography was used to measure the cervical length in 100 women between 14 and 24 weeks of gestation, who had singleton pregnancies that were recommended for elective pregnancy termination. All participants received the same regimen of medical termination of second trimester pregnancy by misoprostol.
Results: A positive correlation was found between cervical length measured by transvaginal ultrasound and duration of termination of second trimetric abortion. Results revealed an equation (Cervical length – Parity + Fetal demise – Rupture of membranes) that can predict duration of termination Conclusion: Transvaginal ultrasonographic cervical measurements has a significant correlation with duration of termination of second trimetric abortion and can be used as a predictor of time of induction of abortion by misoprostol in the second trimester termination of pregnancy.
