RisksBy Mayo Clinic staff
Risks associated with cervical cerclage include:
- Uterine contractions
- Vaginal bleeding
- A tear in the cervix (cervical laceration)
- Inability of the cervix to shorten or open (cervical dystocia)
- Permanent narrowing or closure of the cervix (cervical stenosis)
- An abnormal connection between the bladder and vagina (vesicovaginal fistula)
- Uterine rupture
- Preterm premature rupture of the membranes — when the fluid-filled membrane that surrounds and cushions the baby during pregnancy (amniotic sac) leaks or breaks before labor begins and before week 37 of pregnancy
- Movement of or loosening of the sutures (suture migration)
- Preterm labor
After receiving a cervical cerclage, contact your health care provider immediately if you have leakage of fluid from your vagina, a sign of preterm premature rupture of membranes. Your health care provider might recommend removing the cervical cerclage before week 37 of pregnancy if you have preterm premature rupture of membranes and a uterine infection.
