Cervical cerclage still remains a controversial treatment. It involves placing a stitch around the cervix early in pregnancy (usually at 10-12 weeks) in an attempt to keep the cervix closed. It is probably useful where the cervix may be weak (previously termed 'incompetent') and where miscarriage(s) have occurred at 16-24 weeks before. If you are considering requesting a stitch, you should discuss with a specialist obstetrician with experience in this area, as stitches are performed infrequently.
