Cervical Cerclage
A cervical cerclage is a stitch placed around the cervix during pregnancy to help keep it closed and reduce the risk of premature birth or miscarriage.
Quick answer
Cervical Cerclage: what it is, why it's done and what happens
A cervical cerclage (cervical stitch) is a strong stitch put around the neck of the womb (cervix) to support it and help it stay closed when there is a risk of it opening too early in pregnancy.
- Why it is done: It is used for a weak cervix (cervical insufficiency), often suspected after previous late miscarriages or early births, or when the cervix is found to be shortening or opening during pregnancy.
- What happens: Usually under spinal or general anaesthetic, the obstetrician places the stitch around the cervix through the vagina, typically in the second trimester.

Why it is done
It is used for a weak cervix (cervical insufficiency), often suspected after previous late miscarriages or early births, or when the cervix is found to be shortening or opening during pregnancy.
What happens
Usually under spinal or general anaesthetic, the obstetrician places the stitch around the cervix through the vagina, typically in the second trimester. It is often a short procedure.
Recovery
Some cramping and light bleeding are normal for a few days. Rest may be advised at first. The stitch is usually removed later in pregnancy, around the time labour would be safe, or if labour starts.
Good to know
Risks and things to consider
Risks include infection, bleeding, breaking of the waters and, rarely, injury to the cervix. It reduces but does not remove the risk of early birth, and is only used when there is a clear indication.

Answers
Cervical Cerclage: frequently asked questions
When is the cervical stitch removed?
It is usually removed later in pregnancy, around the point when it would be safe for labour to happen (often around 37 weeks), or earlier if labour begins or there are complications.
Will I still be able to have a vaginal birth?
Often yes. Once the stitch is removed, a vaginal birth is usually possible unless there is another reason for a caesarean. Your obstetric team will plan the safest delivery.
