cerclage

(ser-KLAZH)
A procedure in which a special stitch or band is placed around the cervix to help keep it closed during pregnancy. A cerclage may be done to prevent a miscarriage or premature birth (the birth of a baby before 37 weeks of pregnancy) due to having a weakened cervix. In a person whose cervix has been removed by surgery, the stitch or band is placed on the lower end of the uterus.
