To study the success rate and identify the factors influencing the success rate of external cephalic version (ECV) at Bhumibol Adulyadej Hospital. The subjects were seventy-two, singleton, pregnant women with non-vertex presentation who were at least thirty-six weeks of gestation and had attended the antenatal care clinic between October 1,1997 and September 30, 1999. The success rate of ECV was 75.68 per cent. AFI and fetal weight significantly affected the success rate of ECV, other factors did not. Conclusion: ECV is a safe procedure with a high success rate in selective cases. ECV, thus, is an effective alternative practice for non-vertex presentation which can also reduce the rate of breech delivery and cesarean section.
