Cervical dilation after initial cervical cerclage in twin pregnancies: is repeat cerclage beneficial?

OBJECTIVE: Recently, several studies have shown that ultrasound-indicated cerclage (UIC) might prolong gestation and reduce the risk of spontaneous preterm birth (sPTB) in twin pregnancies.1–3 Cervical dilation after cerclage is not uncommon in clinical practice. Repeat cerclage (RC) has been reported as an option in such cases and might be beneficial for singleton pregnant women.4,5 However, there is limited information on the benefit of placing an RC in women twin pregnancies with cervical dilation.
