The success rate of cervical cerclage is usually around 80% and most of them can be treated with transvaginal cervical cerclage or transabdominal cervical cerclage, which can be performed between 14 and 16 weeks of pregnancy. The success rate after surgery is not only related to the operation performed during the procedure. It is crucial that absolute bed rest and elevation of the hips are also given after the operation and that the fetus needs to be treated with drugs that inhibit contractions. If the fetal heartbeat is good after symptomatic treatment and the woman does not have lower abdominal pain or vaginal bleeding, she should continue fetal preservation treatment until the fetus is mature and the cervical cerclage should be removed. The procedure is performed because the cervical muscle is incomplete and the opening of the cervix is loose. In the middle of pregnancy, the opening of the cervix is often widened and the fetal membranes rupture without pain or the fetus is delivered, which can cause repeated miscarriages.
