But I was wondering if anyone else is experiencing this or has experienced this with past pregnancies. AC together with biparietal diameter, head circumference, and femur length are computed to produce an estimate of fetal weight. The long axis of the diaphysis of the femur is most accurately measured when the ultrasound beam of insonation is perpendicular to the shaft. Increasing fetal AC is predictive of primary cesarean delivery (OR 1.486, p=0.0023). 1. Conclusion A prenatal ultrasound finding of a difference in AC to HC of 50 mm while uncommon is associated with shoulder dystocia.
