Cervicoisthmic cerclage: transabdominal vs transvaginal approach.

Objective: We sought to compare the outcomes of cervicoisthmic (CI) cerclage using traditional transabdominal (TA) approach vs the lesser used transvaginal (TV) approach.

Study Design: We conducted a retrospective cohort study of women who underwent placement of a CI cerclage.

Results: Before CI placement, the abdominal group had a total of 100 pregnancies that continued beyond the first trimester and had 27 (27%) surviving infants.
