RisksBy Mayo Clinic Staff
Risks associated with cervical cerclage include:
- Vaginal bleeding
- A tear in the cervix (cervical laceration)
- Prolapse of the fetal membranes into the vagina
- 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 week 37 of pregnancy
- Preterm labor and premature birth
Keep in mind that if you have cervical dilation in the second trimester, it's possible that you might experience these problems even if you don't have cervical cerclage.
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 early if you have preterm premature rupture of membranes and a uterine infection, depending on your stage of pregnancy.
