Rescue / emergency cervical cerclage
A rescue stitch may give your pregnancy more time.
A discussion for patients whose cervix has started to open in the second trimester.

Understand the purpose. Weigh your options. Know when to call.
The stitch cannot guarantee a full-term pregnancy. This guide focuses on a pregnancy with one baby; care for twins is individualized.

Understanding your body
Your cervix is the lower opening of your uterus.
The uterus is where your pregnancy grows. The cervix connects it to the vagina.
Membranes are the thin layers forming the bag of waters around your baby.
Source: UCLH: Cervical cerclage.
Why this matters
Opening too early can put the pregnancy at risk.
Cervical insufficiency means the cervix opens too soon, sometimes without labor pain. This can lead to pregnancy loss or very early birth.
This diagnosis is not a personal failure.

Before a decision
Your team checks whether a stitch is appropriate.
How far along?
Your pregnancy week and your baby's condition help guide the options.
What has changed?
The examination shows the opening and whether the bag of waters is bulging.
Any warning findings?
The team checks for infection, labor, leaking fluid, and bleeding.
Will I need a fluid test?
Sometimes an amniocentesis is considered to look for infection. A needle takes a small sample of fluid from around the baby. It is not needed in every case; ask why it is being offered.

When the plan changes
Some findings make a rescue stitch unsafe or unlikely to help.
Labor has started
The team evaluates contractions and cervical change.
Infection is present
Infection inside the uterus needs a different care plan.
The waters have broken
Leaking amniotic fluid changes the risks and options.
Significant bleeding
Your team checks the cause before deciding what is safe.
Sometimes the cervix is too far open for a stitch to be placed safely.
Sources: UCLH; RCOG. Full references
Making the decision together
Weigh a stitch against care without one.
Rescue cerclage
A procedure that aims to support the cervix and delay birth.
It carries surgical risks and may not succeed.
Care without a stitch
Monitoring, counseling, and treatments suited to your situation.
The risk of pregnancy loss or very early birth remains.
Your team should explain why it recommends a particular plan. Your questions and priorities matter.

What happens in the operating room
The stitch goes around the cervix through the vagina.
- Pain control. Spinal anesthesia numbs the lower body; general anesthesia puts you to sleep.
- Placement. The surgeon places a strong stitch in the cervical tissue.
- Support. The stitch is tied to help hold the opening closed.
Bulging membranes can make placement more difficult. Your surgeon may gently move them back before placing the stitch.

What the evidence means for you
More time may help. The result remains uncertain.
Longer pregnancy
Studies in selected patients link rescue cerclage with more time before birth and better newborn survival than care without a stitch.
A particular outcome
The stitch may not prevent pregnancy loss or very early birth. Study averages cannot predict what will happen to your baby.
Much of the evidence comes from observational studies. Differences between patients who receive a stitch and those who do not can affect the results.

Your individual outlook
Your examination helps guide the discussion.
Pregnancy timing
The pregnancy week affects the choices and what early birth could mean.
How far the cervix is open
More advanced opening can make a successful outcome less likely.
Bulging membranes
The bag of waters extending past the cervix may increase concern.
Bleeding or infection signs
These findings may change both the outlook and the treatment plan.
One measurement does not decide your baby's future.

Understanding the risks
A rescue stitch has risks as well as possible benefits.
Waters breaking
The membranes may rupture during or after treatment.
Infection
Infection may require treatment and a change in the pregnancy plan.
Bleeding or injury
The cervix or nearby tissues can be injured during surgery.
The stitch may not work
Pregnancy loss or very early birth can still occur.
An emergency stitch has greater risks than a planned stitch placed before the cervix opens.

After the procedure
Leave with a recovery plan made for you.
Brief light spotting can occur. Hospital stay, medicines, and follow-up depend on your situation.
Discuss before going home
Activity, work, lifting, sex, pain relief, and any prescribed medicines.
Routine strict bed rest is not recommended. Follow your team's specific recovery advice.

Get urgent help for warning symptoms.
Contact your maternity team or go to the hospital promptly if you have:
Fluid leaking or a gush of fluid
Fever or chills
Foul-smelling discharge
Heavy or ongoing bleeding
Contractions or repeated cramps
Persistent or worsening pain

Planning ahead
The stitch needs a removal plan.
36–37 weeks
A vaginal stitch is usually removed around this time if the pregnancy continues without a reason to remove it sooner.
Labor or a new problem
Labor needs urgent attention and stitch removal to protect the cervix. If your waters break, the team decides when removal is safest.
If a cesarean is already planned for another reason, ask how that changes the removal plan.

If early birth becomes likely
Your team will discuss the next steps with you.
Support continues even if the stitch cannot keep the pregnancy going.
Your priorities
Share your questions, hopes, and concerns.
Your health
Discuss what is happening and which treatments may help.
Your baby's care
Discuss what birth at this stage could mean and the available care options.
The pregnancy week, clinical findings, available care, and your wishes guide the discussion.

Questions to Ask Your MFM Specialist
MFM means maternal-fetal medicine: a specialist in higher-risk pregnancies.
- Why do you recommend a stitch for me?
- What are the benefits, risks, and alternatives in my situation?
- How do my examination findings affect the outlook?
- Which symptoms need urgent help, and who do I call?
- What are my follow-up, activity, and stitch-removal plans?
Ask for plain-language explanations, an interpreter, or a support person if that helps you.
Discussion prompts based on the preceding evidence and shared decision-making principles.
What to remember
Remember the goal, the warning signs, and your next step.
The goal is more time.
A stitch supports the cervix. It cannot promise the outcome.
New symptoms matter.
Leaking fluid, bleeding, pain, or infection symptoms need prompt assessment.
Know your plan.
Keep your follow-up date and maternity team's phone number handy.
Let's check: what would you do if fluid started leaking?
Contact your maternity team right away or seek hospital assessment. Do not wait for your scheduled visit.
Tell your team that you have a cervical stitch.
