Vaginal cervico-isthmic cerclage versus McDonald cerclage in women with a previous failure of prophylactic cerclage: A retrospective study

Rate of delivery before 30 weeks of gestation was not significantly different between the two groups, but women in the vaginal cervico-isthmic cerclage group seem to be at higher risk for late foetal loss or premature delivery. This procedure generates less threatened premature delivery, thus, less hospitalization and antenatal corticotherapy. These arguments are important for women with previous pregnancy loss.
