title: Transabdominal cervical cerclage in triplet pregnancies and risk of extreme prematurity and neonatal loss.
abstract: There are no reports indicating the effect of prophylactic transabdominal cerclage (TAC) on the prolongation of multifetal pregnancies. We report the use of TAC in triplets, which evolved over 20 years in one practice. A retrospective cohort study of triplet pregnancies was conducted. Obstetric and neonatal outcomes were compared among women who underwent a prophylactic TAC or transvaginal cerclage and no cerclage. Of the 141 women who delivered triplets, prophylactic TAC was associated with reduced incidence of extreme prematurity and improved incidence of neonatal/postnatal survival. With the exception of mode of conception, prepregnancy weight, and the use of home monitoring uterine activity monitor, procardia and terbutaline, no major differences were found in terms of patient characteristics and pregnancy and delivery management among the three groups. It was concluded that in triplet pregnancies, prophylactic placement of a TAC appears to lower the incidence of delivery before 28 weeks.
