cervical cerclage
Pronunciation: /sərˈklɑːʒ/
Surgical procedure involving suture placement around the cervix to prevent preterm delivery in cases of cervical incompetence.
Full Definition
Cervical cerclage is a surgical procedure in which sutures are placed around the cervix to provide mechanical support and prevent preterm cervical dilatation and delivery. The procedure is indicated for cervical incompetence (cervical insufficiency), typically in women with a history of second-trimester pregnancy loss or preterm delivery associated with painless cervical dilatation. Cerclage can be placed electively (prophylactic) in early pregnancy, or emergently when cervical shortening or dilatation is detected on surveillance ultrasound. Types include transvaginal (McDonald or Shirodkar techniques) or transabdominal cerclage. The suture is typically removed at 36-37 weeks or at the onset of labor, and the procedure may be associated with risks including bleeding, infection, and membrane rupture.
Usage
Usage note: French-derived term; 'cerclage' pronounced with soft 'g'.
