External cephalic version of non-cephalic presentation; is it worthwhile?

A retrospective study of 186 consecutive external cephalic versions (ECV) late in the third trimester was done. Logistic regression analysis of background factors leading to a successful ECV showed that multiparity, a larger amount of amniotic fluid, measured as amniotic fluid index, and a transverse fetal position were each significantly correlated with a successful version. The total success rate was 62%, and after a successful ECV 84% of the fetuses were delivered vaginally. No severe complications were registered during the ECVs, and all babies had normal Apgar scores at delivery. Attempting ECV at least once or even twice seems to be appropriate because a successful ECV can decrease the rate of cesarean section in this group of patients and by so doing may also decrease the risk of cesarean section in future pregnancies.
