This is a condition in pregnancy where the cervix begins to open (dilate) too early, often without pain or contractions, typically in the second trimester (around 16–24 weeks). It can lead to miscarriage or preterm birth.
Previous second-trimester pregnancy loss without pain
Cervical trauma (e.g., from D&C, cone biopsy, or LEEP procedure)
Congenital cervical abnormalities
Multiple gestations (twins, triplets, etc.)
History of cervical insufficiency in prior pregnancy
Pelvic pressure
Mild cramping
Vaginal discharge or spotting
Feeling of fullness in the pelvis
Sudden rupture of membranes
This is a surgical procedure to stitch the cervix closed to help prevent early opening. It's usually done between 12–24 weeks of pregnancy.
History-indicated cerclage: Done prophylactically around 12–14 weeks due to a prior history.
Ultrasound-indicated cerclage: Done when a short cervix (<25mm) is found on ultrasound before symptoms develop.
Emergency/rescue cerclage: Done when the cervix is already dilating but membranes are still intact.
