Utility of the pulsatility index of the uterine arteries and human chorionic gonadotropin in a series of cases of placenta accreta.

The conservative management of retained placenta accreta has been proposed as an alternative option in selected cases. Three patients under conservative management of placenta accreta were followed using the pulsatility index of the uterine arteries and the β fraction of human chorionic gonadotropin to determine the degree of vascularity between the uterus and the placenta. In this series of cases of conservative management of placenta accreta, the pulsatility index of the uterine arteries showed a better correlation with the uteroplacental circulation than serum β fraction of human chorionic gonadotropin.
