Clinical Trial Summary

The purpose of the study is to compare the role of cervical cerclage versus expectant management in women with complete placenta previa (≥ 10mm over internal os) presenting with shortened cervical length ( ≥ 10mm and ≤ 30mm) between 18w0d and 26w0d of pregnancy.


Description:

The purpose of this study is to perform a large multi-center randomized trial comparing the role of cervical cerclage versus expectant management in women with placenta previa presenting with shortened cervical length ( ≥ 10mm and ≤ 30mm) between 18w0d and 26w0d of gestation. In addition, the role of fetal fibronectin (fFN) for the prediction of preterm birth and hemorrhage will be elucidated. The hypothesis is that placement of a cervical cerclage between 18w0d to 26w0d in patients with a short cervix and complete placenta previa will decrease preterm birth as compared to expectantly managing these patients.

Intervention

Procedure:
Placement of a Cervical Cerclage
Surgical placement of a cervical cerclage
Standard Expectant Management
Participants assigned to the expectant management group will be followed by their doctor and managed per standard management which includes: Standard management for placenta previa. Hospital admission for vaginal bleeding/hemorrhage Antenatal corticosteroids > 24w0d of gestation Tocolytic therapy per physician's discretion Magnesium sulfate for neuroprotection Fetal Heart Rate Monitoring Avoidance of digital examinations of the cervix Elective delivery no earlier than 36w0d gestation unless indicated (uncontrolled hemorrhage, imminent delivery, PROM > 34 wks, worsening maternal or fetal condition ) Fetal Fibronectin (fFN) test collected at the time of transvaginal Ultrasound.
