Twin Cerclage

The purpose of this research is to determine whether the use of cervical cerclage in women with twin pregnancy and cervical dilation before 24 weeks will prevent, or reduce the occurrence of preterm birth. While some case reports have found that cervical cerclage may prevent preterm birth in twin pregnancies, the use of cervical cerclage to prevent preterm birth in this study is experimental.
