NCT06036446

Brief Summary

The goal of this clinical trial is to determine whether cervical cerclage reduces the risk of preterm birth in patients with a short transvaginal ultrasound (TVU) cervical length (CL) ≤25mm between 24 0/7-26 6/7 weeks.

Drug: Vaginal Suppository Progesterone

Interventions
