The success rate for cervical cerclage is approximately 80-90% for elective cerclages, and 40-60% for emergency cerclages. A cerclage is considered successful if labor and delivery is delayed to at least 37 weeks (full term). After the cerclage has been placed, the patient will be observed for at least several hours (sometimes overnight) to ensure that she does not go into premature labor. The patient will then be allowed to return home, but will be instructed to remain in bed or avoid physical activity (including sexual intercourse) for two to three days, or up to two weeks. Follow-up appointments will usually take place so that her doctor can monitor the cervix and stitch and watch for signs of premature labor.
