Cerclage removal — The cerclage is removed electively at 37 weeks of gestation or immediately upon onset of premature labor in order to avoid cervical laceration and/oruterine rupture. The absolute risk of laceration is unclear, given the small number of reports [61]. Whether to remove the cerclage in the setting of preterm premature rupture of membranes (PPROM) is controversial. (See 'Removal of cerclage after PPROM' below.)

A McDonald cerclage usually can be cut and removed in the office without analgesia. A Shirodkar cerclage often requires a return to the operating room for removal, either because the knot is buried under the vaginal epithelium or the Mersilene tape has been infiltrated by cervical granulation tissue. 

Patients are generally sent home after cerclage removal to await the onset of labor, which generally occurs within two weeks; only about 10 percent of women deliver spontaneously within 48 hours of elective cerclage removal [62].
