Factors Associated With Success of Emergent Second-Trimester Cerclage

A single‐center retrospective study of pregnancy outcomes after emergency cerclage for cervical insufficiency

“…Several studies have showed that membrane prolapse beyond the external os and/or a cervical dilation of 1.5 cm are independent predictors of cerclage failure. 8,10,13 In the present study, seven patients had cervical dilation at the time of the cerclage procedure, and most of these women had poor out- proposed cerclage for women with CL less than 15 mm, whereas a meta-analysis 15 has suggested that cerclage should be done for women with a previous history of preterm birth and CL less than 25 mm.…”

Pregnancy outcome after placement of ‘rescue’ Shirodkar cerclage

“…In 2003 Terkildsen et al 12 identify factors associated with delivery greater than or equal to 28 weeks' gestation after placement of an emergent cerclage in women with singleton gestations. They concluded that nulliparity, the presence of membranes prolapsing beyond the external cervical os, and gestational age less than 22 weeks at cerclage placement were associated with decreased chance of delivery at or after 28 weeks after emergent cerclage.…”

Favorable outcome following emergency second trimester cerclage

“…The clinical presentation is often characterized by advanced cervical dilation with or without protrusion of the fetal membranes into the vagina. Cerclage is sometimes performed under these circumstances in spite of the reported unfavorable prognosis [4–13].…”
