A cervical suture is an operation where a suture (stitch) is placed around the cervix (neck of the womb). It is also sometimes known as cervical cerclage. It is usually done at between 12 and 24 weeks of pregnancy.
A cervical suture is sometimes recommended for women who are thought to have a high chance of a late miscarriage or of going into premature labour. The purpose of the suture is to reduce the risk of your baby being born early. Premature babies have an increased risk of short- and long-term health problems.
