The use of ultrasound-indicated cerclage or cervical pessary in asymptomatic twin pregnancies with a short cervix at midgestation.

Introduction: Spontaneous preterm birth in women with a twin pregnancy is one of the main causes of perinatal mortality and morbidity. Our aim was to review the perinatal outcome of asymptomatic twin pregnancies with a sonographic short cervical length during the second trimester treated with an ultrasound-indicated cerclage or cervical pessary.

Material And Methods: Retrospective study on asymptomatic twin pregnancies with a short cervix (≤ 25 mm) at transvaginal ultrasound examination during the second trimester treated with a cervical cerclage or pessary (2001-2017).
