Successful cerclage in two patients with advanced cervical dilatation in the second trimester.

Emergency cerclage in the second trimester is a recognized treatment for a dilatated cervix. Cervical cerclage is usually not attempted with advanced degrees of cervical dilatation because of the poor chances of survival. We had two rare cases of successful cerclage at advanced cervical dilatation in the second trimester and both delivered healthy babies at full term.
