Assessment of cervical length by transvaginal ultrasonography to predict preterm delivery in twin pregnancy.

Objective: In singleton pregnancy, short cervix is associated with the risk of spontaneous preterm delivery (SPD). On the other hand, twin pregnancy increases rate of preterm delivery, so this study was designed to evaluate the transvaginal sonographic (TVS) measurement of cervical length (CL) to predict preterm birth in twin pregnancy.

Methods: This prospective cohort study was performed on 80 twin pregnant women whom the length and funneling of their cervix were evaluated between 22-24 gestational weeks by (TVS).
