What Are the Risks Associated with Cervical Cerclage?

Pregnancy is a very difficult process for women, and various complications may occur during childbirth, such as premature birth, placenta previa, and multiple pregnancies. In these cases, ordinary delivery methods cannot be used, and cervical cerclage is required to address the issue. Many pregnant women are experiencing childbirth for the first time, and when they first encounter cervical cerclage, they are bound to be concerned about its potential risks. So, what are the risks of cervical cerclage? Let's take a look.

Cervical cerclage is a surgical procedure that closes the internal cervical os, generally considered a minor to moderate operation. It is suitable for pregnant women with cervical incompetence, who may have a history of multiple mid-to-late term miscarriages or preterm births. Cervical incompetence is most often caused by congenital factors, but it can also be caused by acquired factors such as a history of difficult childbirth. Cervical cerclage also carries certain risks, which can include cervical tears, bladder and urethral injuries, premature rupture of membranes leading to miscarriage, and severe cases can lead to inflammation of the amniotic sac, resulting in intrauterine infection and inflammation.

1. Habitual miscarriage and preterm birth caused by cervical incompetence. The surgery can prolong the pregnancy duration and improve the survival rate of newborns.

2. Placenta previa: Cervical cerclage can prevent the extension of the lower uterine segment and the dilation of the cervical os, making it less likely for the placenta to become dislocated or detached from the uterine wall.

3. Twin or multiple pregnancies: Excessive uterine distension in twin or multiple pregnancies is one of the main causes of premature rupture of membranes and preterm birth. Cervical cerclage can prolong the gestational period and significantly improve the survival rate of fetuses in multiple pregnancies.

1. Adopt a high hip and low head position for 3-5 days before surgery, and use beta-blockers or intravenous magnesium sulfate to suppress uterine contractions during and after surgery.

2. Vaginal inflammation should be treated if present.

3. Rest in bed after surgery, and continue to use uterine relaxants and antibiotics to prevent infection. If necessary, prolonged bed rest may be required.

4. Regular follow-up appointments should be scheduled after surgery, and hospitalization should be arranged early. If there are signs of labor after the cerclage, and uterine contractions occur despite treatment, the sutures should be removed promptly to avoid cervical tears.

5. The cervical sutures should be removed at 37-38 weeks of gestation or before childbirth.
