Cervical pessary
Cervical pessary is a medical device used to treat an incompetent (or insufficient) cervix (cervix starts to shorten and open too early). Early in the pregnancy a round silicone pessary is placed at the opening to the cervix to close it, and then it's removed later in the pregnancy when the risk of a preterm birth has passed.[citation needed]
Pregnant women are at risk of giving birth too early when their cervix begin to efface (shorten) and dilate (open). Different treatments have been tried to prevent a late miscarriage or preterm birth. A common treatment is cervical cerclage or stitch when a suture is stitched around the opening of the cervix around 12–14 weeks into the pregnancy.[1]
A cervical pessary is being studied as an alternative to cervical cerclage since there are fewer potential complications.[2] More medical studies are needed to decide whether a cervical pessary is equal to or the best treatment.[2][3]
