What to expect from cervical cerclage for preterm labour

Preterm labour involves contractions and cervical change before the pregnancy is ready for birth. A cerclage may be considered in selected situations where the cervix is shortening or opening, but it is not suitable when active labour, infection or ruptured membranes is present. Ultrasound, examination and your pregnancy history guide the decision.

During the procedure, an anaesthetic is used while a stitch is placed around the cervix through the vagina. You may have monitoring, an internal examination and medicines according to your symptoms. The stitch is not a treatment for every cause of preterm labour, so the team will also discuss observation and other care if needed.

Follow the discharge plan for activity, medicines and follow-up. Mild cramps or light spotting may occur, but avoid assuming that new tightening is normal. Note the timing of pain, contractions, bleeding or fluid loss so you can describe changes accurately. Ask before resuming sex, exercise or travel, since advice depends on your findings.

Call your maternity unit urgently for regular contractions, increasing pelvic pressure or backache, vaginal bleeding, a gush or continuous trickle of fluid, fever, unpleasant-smelling discharge or severe pain. These signs can indicate labour, infection or membrane rupture, and the stitch may need immediate review.

Ask what finding makes cerclage reasonable, what alternatives exist, how the procedure could affect your care, when the stitch should be removed and which symptoms require a same-day assessment.
