The therapeutic effect of cervical cerclage in pregnancy with cervical incompetence

The shortening of the cervix, cervical incompetence or insufficiency that causes late miscarriage or preterm birth syndrome gives importance and clinical significance for the cervical cerclage or cervical stitch as treatment. Nowadays closure of the cervix with cerclage surgery is an effective way of preventing premature opening of the cervix, helping the pregnancy near due date, thus significantly reducing the risk of miscarriage and premature delivery.

The retrospective longitudinal cohort study is based on an examination of 164 pregnant woman who underwent cervical cerclage surgery at Obstetrics and Gynecology Clinic nr. I Târgu-Mureș, between 2000-2017. The McDonald’s method was used in every case that we have studied.

Cerclage surgery was performed in most cases in the second trimester. The results in the study reflect that in the majority of the cases, intervention is effective in preventing premature opening of the cervix. Most women are multipara and had multiple gestational pregnancy, which can also contribute to the weakening and early opening of the cervical closure system. In 66.5% of the cases, at least one abortion or miscarriage is present in the history of the disease, which may also lead to a weakening of the cervical closing function.

Following cerclage surgery, 11.6% abortion and 88.4% in childbirth occurred, and in most cases, intervention can effectively prevent second trimester abortion while reducing the risk of premature birth (65, 8% had no premature birth in our study).
