Study Arms:
- Study group (Type: EXPERIMENTAL): The study group will be constituted by pregnant women in whom the operative delivery will be preceded by a transabdominal and transperineal ultrasound to evaluate fetal head position and fetal head station, by means of determination of the 'angle of progression'.
- Control group (Type: NO_INTERVENTION): The control group will be constituted by pregnant women in whom the operative delivery will be carried out based solely on clinical criteria, namely transvaginal digital examination.

Based on this trial design, predict the completion outcome and termination type (if applicable).
