Cerclage (Cervical Stitch): Procedure, Timing, and Outcomes

Cerclage places a suture around the cervix to prevent premature dilation in cervical insufficiency (painless dilation → preterm birth).

Procedure Details

• Timing: Typically 12–14 weeks (late 1st/early 2nd trimester).
• Technique: Transvaginal (McDonald, Shirodkar) or transabdominal.
• Setting: Outpatient; <30 minutes.

Post-Procedure

• Activity restriction (avoid heavy lifting, intercourse) for several weeks.
• Serial cervical length monitoring via ultrasound.
• Removal at 36–37 weeks or earlier if labor starts.

Risks

• Infection, bleeding, cervical injury, preterm labor, PROM.

Success rates are high for indicated patients. Discuss candidacy with your MFM specialist.
