cerclage
Pronunciation: sur-KLAHZH
Surgical procedure placing sutures around the cervix to prevent preterm birth due to cervical insufficiency.
Full Definition
Cervical cerclage is a surgical procedure in which sutures are placed around the cervix to provide mechanical support and prevent premature cervical dilation in women with cervical insufficiency (incompetent cervix). The procedure can be performed via transvaginal or transabdominal approach, with timing depending on indication—prophylactic (history-based), therapeutic (ultrasound-indicated), or emergency (rescue cerclage). Common techniques include the McDonald cerclage (simple purse-string suture) and Shirodkar cerclage (more anatomically placed suture). Cerclage aims to prolong pregnancy and reduce the risk of preterm birth, with removal typically planned around 36-37 weeks of gestation.
