Background: In twin pregnancies where the presenting twin is not cephalic, cesarean delivery is the standard of care. External cephalic version (ECV) has been used for malpresenting singleton pregnancies with low risk of complications. ECV in twin pregnancies is poorly studied.
Objective: To assess feasibility and report any complications of ECV of a malpresenting twin before labor.
Study design: This is a prospective cohort of twin pregnancies with malpresenting first twin. Inclusion criteria included English or Spanish speaking women. Exclusions included cases where there was a contraindication to vaginal delivery. ECV was performed according to the institutional singleton protocol. Fetal testing of both twins was performed before and after procedure. A vaginal hand was used during ECV as needed. The primary outcome was success of the procedure. Secondary outcomes included delivery characteristics and neonatal outcomes.
Results: Five patients were enrolled in this study. Four patients underwent successful ECV and vaginal delivery occurred in 2 of the 4 patients. ECV procedure was performed at a mean gestational age of 36+0 weeks in the successful ECV group and 36+6/7 weeks for the unsuccessful group. Latency to delivery was 4.5 days in the successful ECV group and 1 day in the unsuccessful ECV group. No maternal or neonatal complications occurred in any participating women.
Conclusion: ECV in twin pregnancies where the first twin is malpresenting was feasible in our cohort. More research is needed to better characterizer the safety and efficacy of this procedure in this patient population.
