The Angle of Progression at Station 0 and in Magnetic Resonance and Transperineal Ultrasound Assessment

The Angle of Progression at Station 0 and in Magnetic Resonance and Transperineal Ultrasound Assessment

The transperineal ultrasound (TPU) value of the angle of progression (AOP) during fetal head engagement, at station 0, is a critical cut-off for current obstetrical practice, especially when intrapartum instrumental interventions are required. Still, controversial measurements were reported in previ...
