Cervical cerclage is a surgical procedure to reinforce the cervix and prevent preterm birth by stitching it closed during pregnancy.
Understanding Cervical Cerclage and Its Purpose
Cervical cerclage is a specialized surgical technique aimed at reducing the risk of premature birth or miscarriage due to cervical insufficiency. This condition occurs when the cervix, which normally remains tightly closed during pregnancy, begins to open too early, often without pain or contractions. The premature opening can lead to pregnancy loss or early delivery, sometimes weeks or months before the baby is fully developed.
The procedure involves placing strong sutures around the cervix to keep it closed and provide mechanical support. It’s typically recommended for women who have experienced second-trimester losses or preterm births linked to a weak cervix. In some cases, ultrasound scans reveal a shortening cervix that signals the need for cerclage before symptoms arise.
Cervical cerclage can be a game changer for many pregnancies at risk. It’s not a routine intervention but rather a targeted measure when specific risk factors are present. The goal is clear: maintain pregnancy long enough for fetal development to reach viability and beyond.
Types of Cervical Cerclage Procedures
There are three main types of cervical cerclage, each tailored to different clinical situations:
1. McDonald Cerclage
This is the most common type. The surgeon places a purse-string suture around the cervix near its opening. It’s usually done between 12 and 14 weeks of pregnancy and removed around 37 weeks or earlier if labor begins.
2. Shirodkar Cerclage
A bit more complex than McDonald, this technique involves dissecting tissue around the cervix before placing the stitch higher up and deeper into the cervical tissue. It’s often used when anatomical variations or previous surgeries make McDonald less effective.
3. Transabdominal Cerclage
This is reserved for women who failed previous vaginal cerclages or have an extremely short or damaged cervix. The suture is placed through an abdominal incision near the top of the cervix. This type may remain in place for future pregnancies as well.
Each method has its pros and cons based on individual patient history and anatomy, but all share one goal: preventing premature cervical dilation.
When Is Cervical Cerclage Recommended?
Doctors decide on cervical cerclage based on specific clinical criteria:
- History-Indicated: Women with previous painless mid-trimester losses or preterm births related to cervical insufficiency.
- Ultrasound-Indicated: Detection of a short cervix (usually less than 25 mm) during mid-pregnancy in women with risk factors.
- Physical Exam-Indicated: When early cervical dilation is found during pregnancy without contractions.
The timing of placement matters greatly. Most cerclages happen between 12-14 weeks gestation if history indicates risk, but ultrasound-indicated ones may be placed later once shortening is detected.
It’s important to note that not all cases of preterm labor benefit from cerclage; inflammation or infection-driven early labor requires different treatment approaches.
The Cervical Cerclage Procedure Explained
The actual procedure typically takes less than an hour and is done under regional anesthesia—usually spinal or epidural—or sometimes general anesthesia depending on circumstances.
Here’s what happens step-by-step:
- The patient lies on her back with legs in stirrups.
- The vagina and cervix are cleaned thoroughly with antiseptic solution.
- A speculum holds the vaginal walls open for visibility.
- The surgeon places one or more strong nylon or polyester sutures around the cervix near its opening.
- The stitch is tightened just enough to close the cervical canal without causing damage.
- The speculum is removed; bleeding is minimal if any.
Patients usually stay under observation for several hours afterward before going home the same day unless complications arise.
Recovery After Cervical Cerclage
Recovery varies but generally includes some mild cramping or spotting in the first few days after surgery. Most women can return to light activities within a week but should avoid heavy lifting, strenuous exercise, and sexual intercourse until cleared by their doctor.
Doctors often recommend:
- Avoiding prolonged standing
- Limiting physical exertion
- Monitoring for signs of infection such as fever or unusual discharge
- Regular prenatal visits with ultrasounds to check cervical length and fetal health
Bed rest used to be standard advice but nowadays it’s more individualized based on symptoms and overall pregnancy health.
Risks and Complications Associated With Cervical Cerclage
While generally safe, cervical cerclage carries some risks that patients should understand fully:
| Risk/Complication | Description | Frequency/Notes |
|---|---|---|
| Infection (Chorioamnionitis) | Bacterial infection of membranes surrounding fetus leading to fever, uterine tenderness. | Affects about 1-5% of cases; prompt treatment essential. |
| Cervical Injury/Bleeding | Tearing or trauma from suture placement causing bleeding or scarring. | Rare but possible; carefully performed by experienced surgeons reduces risk. |
| Suture Displacement/Failure | Suture loosening leading to reopening of cervix prematurely. | Occurs occasionally; close monitoring needed post-procedure. |
| Pain/Discomfort Post-Surgery | Mild cramping common; severe pain unusual and warrants evaluation. | Mild discomfort expected; managed with simple analgesics. |
| Labor Induction Due To Procedure | Cerclage may stimulate contractions leading to early labor in rare cases. | Uncommon but serious; emergency removal might be necessary. |
| Suture Removal Complications | Difficult removal can cause bleeding or injury during delivery planning stage. | Sutures usually removed at term (around 36-37 weeks). |
Close follow-up care helps catch any complications early so they can be managed effectively.
The Role of Ultrasound Monitoring Post-Cerclage Placement
Ultrasound plays a crucial role after placing a cerclage by tracking cervical length and fetal well-being regularly throughout pregnancy. A shortening cervix despite cerclage might indicate increased risk requiring additional interventions like activity modification, medications such as progesterone, or even hospitalization in severe cases.
Ultrasound also helps determine when it’s safe to remove stitches—usually after 36-37 weeks unless labor starts earlier—and assesses amniotic fluid levels plus fetal growth parameters.
These scans provide reassurance that both mother and baby are doing well following surgery.
Lifestyle Adjustments After Cervical Cerclage Surgery
Adjusting daily habits post-cerclage supports optimal outcomes:
- Avoid heavy lifting over 10 pounds as it increases intra-abdominal pressure that can stress sutures.
- No sexual intercourse until your healthcare provider says it’s okay—usually after healing completes around two weeks post-op.
- Avoid prolonged standing which may increase pelvic pressure; take breaks sitting down frequently if your job requires standing long hours.
- Keep hydrated and eat nutritious foods rich in protein, vitamins C & D, calcium, magnesium—all support tissue repair and immune health.
- If advised bed rest is necessary due to symptoms like contractions or bleeding, follow instructions carefully without overexertion.
- Avoid smoking completely since it impairs blood flow critical for healing and fetal development.
These adjustments aren’t meant as permanent lifestyle changes but temporary measures while your body recovers from surgery and pregnancy progresses safely.
Cervical Cerclage- What To Expect During Delivery?
As delivery approaches near term (around 37 weeks), your doctor will plan suture removal unless a cesarean delivery has been scheduled where stitches might stay in place permanently (transabdominal type).
Removal usually occurs during an outpatient visit shortly before labor onset. The process involves gently cutting stitches via speculum examination—a quick procedure causing minimal discomfort.
If spontaneous labor starts before removal, emergency removal may be necessary since leaving stitches intact could cause cervical tearing during delivery attempts through the birth canal.
Most women with successful cerclages deliver healthy babies at term either vaginally after stitch removal or via cesarean section if indicated due to other obstetric reasons.
