Cervical cerclage may be useful either as a preventative or therapeutic measure in women at risk for preterm delivery (PTD). The 2 common types of management currently used in pregnant women at high risk of PTD are transvaginal measurement of cervical length, or assessment of risk and need for intervention based on obstetric history. Because the RR of a pretenn birth increases with shortening cervical length, ultrasound measurement of cervical length in a woman with a previous preterm birth could help target those needing cerclage. Currently, history-indicated cerclage is inserted only in women with prior multiple pregnancy losses., Suggestions have been made that identification of the ultrasono-graphically short cervix with cerclage may reduce the need for a cerclage based on a history of only 1 previous PTD. This randomized controlled trial compared use of ultrasound-indicated cervical cerclage in pregnant women with a short cervix (
