Cervical stitch during pregnancy: what to know

Also called cervical cerclage, the treatment places strong suture material around the cervix to help it remain closed. Whether it is suitable depends on pregnancy history, ultrasound findings, examination findings, symptoms, and the obstetric team's assessment.

The cervix normally stays closed during pregnancy and then softens and opens for birth. A stitch may be discussed when previous pregnancy outcomes or a shortening cervix suggest that it could open too soon. A planned stitch is commonly placed through the vagina under anaesthesia. In selected circumstances, an abdominal approach or an urgent stitch after the cervix has started opening may be considered.

Cerclage cannot prevent every early birth, and it is not appropriate in every situation. Active labour, significant bleeding, infection, or broken waters can change whether placement is advisable. Your obstetrician should explain the expected benefit in your case, procedural risks, anaesthesia, and other options such as cervical monitoring or progesterone when relevant.

Before the procedure, follow instructions about eating, drinking, and regular medicines. Tell the team about allergies, discharge, bleeding, contractions, or possible fluid leakage. Ask whether you need someone to take you home and what activity, work, exercise, and sex guidance applies afterward.

Mild cramping or light spotting can occur after a vaginal stitch, but the maternity unit should give you clear discharge instructions. Attend planned scans and reviews, and know the removal plan. A vaginal stitch is generally removed before labour or earlier if labour begins or the waters break; an abdominal stitch follows a different birth plan and is not managed in the same way.

Contact maternity triage immediately for regular contractions or tightening, increasing pelvic pressure, vaginal bleeding, a gush or ongoing trickle of fluid, fever, chills, foul-smelling or unusual discharge, or worsening abdominal or back pain. Also call if fetal movement is reduced once you normally feel a regular movement pattern. Do not wait for a routine appointment, because the team may need to check for labour, infection, or ruptured membranes.

Ask what finding led to the recommendation, which type of stitch is proposed, and what the alternatives mean for you. Confirm how the procedure will be performed, which symptoms should prompt a call, whether follow-up scans are planned, when removal is expected, and how the stitch affects the timing or method of birth.
