Cervical Cerclage
Cervical Cerclage
In 2026, Cervical Cerclage—often called a "cervical stitch"—is a critical preventative procedure used during pregnancy to treat cervical insufficiency (an incompetent cervix). This condition occurs when the cervical tissue weakens and begins to open (dilate) too early, which can lead to late-term miscarriage or premature birth.
When You Should Consider Cervical Cerclage
Prophylactic (History-Based): For women with a history of previous second-trimester losses or preterm births, usually performed between 12 and 14 weeks.
Therapeutic (Ultrasound-Based): When an ultrasound identifies a significantly shortening cervix (typically less than 25mm) in high-risk patients.
Emergency (Rescue): When the cervix has already begun to dilate and fetal membranes are visible, serving as a high-stakes intervention to save the pregnancy.
Cervical Insufficiency: Diagnosed weakness in the cervical tissue that cannot support the weight of a growing pregnancy.
Failed Progesterone Therapy: When hormonal treatments are insufficient to prevent cervical shortening.
Methods of Cervical Cerclage
McDonald Technique: The most common vaginal approach where a permanent stitch is placed around the mid-portion of the cervix.
Shirodkar Technique: A slightly more complex vaginal method where the stitch is placed higher up, closer to the internal opening of the cervix.
Transabdominal Cerclage (TAC): Performed via laparoscopy or robotic surgery at the very top of the cervix; usually reserved for cases where vaginal stitches have failed.
Robot-Assisted Cerclage: Utilizing advanced robotic systems for high-precision placement in complex anatomical cases.
Emergency Stitching: Specialized "rescue" techniques used to carefully reposition membranes before sealing the cervix.
How Cervical Cerclage Is Performed
Anesthesia: The procedure is typically performed under regional anesthesia (spinal or epidural) to ensure the patient is pain-free.
Positioning: The surgeon accesses the cervix through the vaginal canal while the patient is in a relaxed state.
Drawstring Suture: A strong, synthetic thread is woven around the cervical tissue and pulled tight, similar to a drawstring bag.
Monitoring: The surgical team monitors for uterine contractions or signs of preterm labor immediately following the stitch placement.
Duration: The vaginal procedure is relatively quick, often taking between 20 to 45 minutes to complete.
Pre-Procedure Preparation
Fasting: Patients must fast for 8–12 hours before the surgery to ensure safety during anesthesia.
Fetal Assessment: An ultrasound is performed immediately before the procedure to confirm the baby's health and position.
Infection Screening: Swabs and blood tests are taken to rule out any active vaginal or pelvic infections.
Medication Review: Discussing any history of uterine contractions or sensitivity to anesthesia.
Recovery Planning: Arranging for a support person to assist with transport and initial home monitoring.
Tests Before Cervical Cerclage
Transvaginal Ultrasound: To measure the length and shape (funneling) of the cervix.
Blood Tests (CBC): To check for signs of infection or inflammation that could complicate the surgery.
Urinalysis: To ensure there is no urinary tract infection (UTI) present.
Fetal Heart Rate Monitoring: To establish a baseline of the baby's well-being.
Amniotic Fluid Assessment: In emergency cases, checking for the presence of the amniotic sac in the vaginal canal.
Life After Cervical Cerclage
Hospital Stay: Most patients go home the same day or after one night of observation for contractions.
Immediate Symptoms: Mild cramping and light spotting are considered normal for 48–72 hours post-op.
Pelvic Rest: Strict avoidance of intercourse, tampons, and douching for the remainder of the pregnancy.
Stitch Removal: The suture is typically removed in-office at 36 or 37 weeks to allow for a normal vaginal delivery.
Activity Management: While strict bed rest is rarely mandated in 2026, patients are advised to avoid heavy lifting and high-impact exercise.
Benefits of Cervical Cerclage
Pregnancy Prolongation: Highly effective at extending gestation, with success rates between 70% and 90%.
Reduced Prematurity Risk: Lowers the likelihood of extremely early preterm birth (before 28 weeks).
Life-Saving Intervention: Acts as a critical "rescue" for pregnancies where the cervix begins to open prematurely.
Future Planning: Transabdominal options provide a long-term solution for women with recurring cervical issues.
Minimally Invasive: Most techniques involve no external incisions and allow for a quick physical recovery.
