When a woman’s cervix is weak—often referred to as an incompetent cervix—there is an increased risk of premature birth due to the cervix shortening or opening too early. To help prevent premature labor, a healthcare provider may recommend a cervical cerclage.
A cervical cerclage is a surgical procedure designed to secure the cervix during pregnancy, keeping it closed to support fetal development until around 37-38 weeks. This procedure is especially important for women whose cervix is at risk of opening due to various factors.
What is a Cervical Cerclage?
Cervical cerclage involves stitching the cervix closed to prevent premature labor. The cervix, which is the lower part of the uterus that opens into the vagina, may require this intervention if it’s deemed weak or at risk.
Why is Cervical Cerclage Necessary?
This procedure is typically recommended for women whose cervix could open under the pressure of a growing fetus. Conditions that might necessitate a cerclage include:
- A history of miscarriages during the second trimester
- Previous surgical procedures like cone biopsies or LEEP
- Damage to the cervix from past abortions
When Should a Cervical Cerclage be Performed?
The optimal time for placing a cervical cerclage is during the third month of pregnancy (between 12-14 weeks). In certain cases, it may be necessary to perform an emergent cerclage if there are signs of cervical changes such as opening or shortening later in pregnancy.
If an emergency cerclage is needed, future pregnancies might also require this procedure.
Alternatives to Cervical Cerclage
If cervical changes are detected late in pregnancy, bed rest may be suggested as an alternative to surgery.
Benefits of a Cervical Cerclage
Cervical cerclage can significantly reduce the risk of miscarriage or premature labor associated with an incompetent cervix. Success rates for this procedure range from 85% to 90%. It’s crucial to note that while cerclage can be effective, diagnosing cervical incompetence can be challenging and sometimes inaccurate.
Why Not Cerclage for Every Woman with a Preterm Baby?
Not all women who have experienced preterm births require a cerclage. The procedure is only beneficial for those with an incompetent cervix. Even with a cerclage, other complications might trigger early labor, so ongoing monitoring for signs of infection and preterm labor is essential.
What to Expect Before the Procedure
Before undergoing a cervical cerclage, expect the following:
- A review of your medical history
- A thorough cervical examination, possibly including a transvaginal ultrasound conducted by a specialist in high-risk pregnancies
- A discussion about pain management options
It’s always a good idea to jot down any questions or concerns to discuss with your healthcare provider.
During the Cervical Cerclage Procedure
Most women receive general, spinal, or epidural anesthesia for the procedure. A doctor will place a strong thread around the cervix, tightening it to keep the cervix securely closed.
Post-Procedure Expectations
After the cerclage, you may remain in the hospital for a few hours or overnight for monitoring. Light bleeding and mild cramping are common immediately following the procedure. This may be followed by a thicker vaginal discharge that could persist throughout the pregnancy.
You may also be prescribed medication to help prevent infection or preterm labor. For a couple of days after the procedure, it’s advisable to rest and limit physical activity. Your doctor will guide you on when to resume normal activities, and sexual intercourse is often advised against for at least a week before and after the procedure.
Duration of the Stitch
Typically, the cerclage stitch is removed around the 37th week of pregnancy. However, it may be taken out earlier if labor starts or if your water breaks. Most removals are straightforward, akin to a pap smear, with some light bleeding possible.
Risks Associated with Cervical Cerclage
The risks are minimal, and many healthcare professionals believe that the benefits of a cerclage outweigh potential complications. Possible risks include:
- Premature contractions
- Cervical dystocia, where the cervix fails to dilate normally during labor
- Rupture of membranes
- Cervical infections
- Cervical lacerations if labor occurs before the cerclage is removed
- Side effects from general anesthesia, such as nausea
Signs to Watch For After the Procedure
It’s crucial to inform your doctor if you experience any of the following symptoms post-cerclage:
- Contractions or cramping
- Intermittent lower abdominal or back pain similar to labor
- Vaginal bleeding
- Fever above 100°F or chills
- Nausea and vomiting
- Unpleasant-smelling vaginal discharge
- Water breaking or leaking
