Cervical incompetence

About this activity

Cervical insufficiency (cervical incompetence) is defined by the American College of Obstetricians and Gynecologists (ACOG) as the inability of the uterine cervix to retain a pregnancy in the second trimester, in the absence of uterine contractions.[1] It typically presents as acute, painless dilatation of the cervix, which can lead to a midtrimester pregnancy loss. In women with this history, the risk of recurrence in a subsequent pregnancy is less than 30%.[2]
