value of the fetal pelvic index in the management of cases with cesarean scar

ABSTRACT

The fetal-pelvic index is a recently described method for identifying the presence or absence of fetal-pelvic disproportion. In this study, the efficiency of the fetal-pelvic index was evaluated in 68 gravid women with single vertex term uneventful pregnancy and history of a prior cesarean section. All women were in labor and fulfilled criteria for a trial of labor. By means of individually measured fetal and maternal pelvic diameters, circumferences of the fetal head, fetal abdomen maternal pelvic inlet, and maternal midpelvis were computed. Based on four circumferences between the fetus and maternal pelvis, a fetal pelvic index number was derived from the sum of the two most positive values
