Pregnancy outcomes and factors affecting the clinical effects of cervical cerclage when used for different indications: A retrospective study of 326 cases

Abstract

Pregnancy outcomes were similar when compared between history-indicated and ultrasound-indicated cerclage. Serial cervical surveillance is beneficial for pregnant with a history of cervical insufficiency, and the placement of cervical cerclages in response to ultrasonographically detected shortening of the cervical length is a medically acceptable alternative to the use of history-indicated cerclage.
