Cerclage (Cervical Stitch) in Pregnancy: What to Expect, When It's Needed, and Safety Tips
Cervical cerclage—also known as a cervical stitch—is a procedure where a specialist places a strong suture or band to help keep the cervix closed during pregnancy. This intervention is typically considered for pregnant women at higher risk of preterm birth or late miscarriage, especially if cervical insufficiency (when the cervix opens too soon) has been diagnosed.
If you've experienced previous pregnancy losses, preterm labor, or have been told on an ultrasound that your cervix is shortening, a cervical cerclage could help support the pregnancy and reduce the risk of early delivery. Facing this diagnosis can be overwhelming, but you’re not alone. Many women need cerclage for a safe pregnancy, and for most, the outcome is positive.
What exactly is cervical cerclage? 🧵
A cervical cerclage is a minor surgical procedure where the doctor places a permanent or removable stitch—sometimes a special tape—around your cervix. The main purpose is to keep the cervix closed until your baby reaches a safer stage of development.
This is usually done by creating a supportive loop around the cervix with strong medical-grade thread or a synthetic band. The stitch works as a mechanical reinforcement, helping prevent the cervix from opening too soon, which lowers the risk of preterm labor or late miscarriage.
Cervical cerclage is most often performed between weeks 12 and 14 of pregnancy, but in some cases, it may be recommended later if ultrasound or physical exam shows warning signs.
When is a cervical stitch recommended?
Doctors typically suggest cerclage if you:
- Have a history of spontaneous preterm birth or second-trimester miscarriage,
- Show signs of cervical shortening or early opening,
- Are found during pregnancy scans or exams to have a cervix measuring 25 mm or less.
Cerclage decisions are always made after carefully weighing your personal risk factors. It may not be advised if there’s an active infection, heavy bleeding, or if the pregnancy is already advanced.
How is cervical cerclage performed? 🤍
The procedure usually requires a day in hospital and is carried out under general or local anesthesia.
Cerclage generally involves these steps:
- Preparing you for the procedure and administering anesthesia.
- Gently accessing the cervix through the vagina.
- Using a surgical suture or tape to create a loop around the cervix.
- Securing the stitch with a knot to keep the cervix closed until late pregnancy.
- Monitoring you for several hours after the procedure, after which most women can return home.
In rare situations, an abdominal cerclage (through the belly) is recommended, but this is reserved for special cases and involves a more complex surgery.
Real-life situations: When is cerclage needed?
- Annamaria had her cerclage placed at week 13, after experiencing preterm birth with her first baby (born at 23 weeks). In her second pregnancy, doctors detected a short cervix, and the cerclage helped her carry to a safer point.
- Sylvia underwent cerclage at week 20, when ultrasound showed her cervix starting to open. Afterward, she needed closer monitoring and more rest.
These examples highlight how the decision for a cervical stitch is always individualized by your healthcare team.
How will cerclage affect my day-to-day life? 💡
Most moms return to light daily activities relatively soon after cerclage, but a few important changes are recommended:
- Avoid heavy lifting or strenuous physical activity.
- Sexual intercourse is typically discouraged for a few weeks.
- Frequent check-ups and ultrasounds might be necessary for ongoing safety.
It’s important to notify your healthcare provider right away if you experience unusual symptoms—such as bleeding, severe pain, high fever, or fluid leakage.
What are the possible risks and side effects of cerclage?
While cerclage is routine and generally low-risk, every procedure has some potential complications:
- Infection (such as endometritis or chorioamnionitis),
- Premature rupture of membranes,
- Bleeding,
- Cervical injury,
- Occasional contractions or cramping,
- Rarely, the stitch loosening or shifting before planned removal.
Serious complications are uncommon, affecting only a small percentage of cases. For most women, the benefits of prolonging the pregnancy outweigh the risks, but your doctor will guide the decision based on your specific situation.
When to contact your doctor after cerclage 🚩
You should contact your doctor or seek urgent care right away if you experience:
- Bright red vaginal bleeding,
- Signs of leaking amniotic fluid,
- Severe or persistent lower abdominal pain or cramping,
- Fever or chills,
- Noticeable decrease in your baby’s movements.
Catching warning signs early can protect your health and your baby—stay observant and reach out promptly if you’re concerned.
