Objective: To assess whether subpubic arch angle (SPA) measurement before labor onset can predict labor outcome among low-risk pregnant women. Methods: 3D ultrasound volume was transperineally acquired from a series of nulliparous women with uncomplicated pregnancy at term before the onset of labor. SPA was measured offline using Oblique View Extended Imaging (OVIX) on each volume performed by an investigator not involved in the clinical management. Labor outcome was prospectively investigated in the whole study group. Results: Overall, 145 women were enrolled in the study. Of these, 83 underwent spontaneous vaginal delivery, whereas obstetric intervention was performed in 62 cases (Cesarean section in 40 and vacuum extraction in 22). The SPA appeared to be significantly narrower in the women submitted to obstetric intervention compared with those undergoing spontaneous vaginal delivery (116.8 ± 10.3° vs. 123.7 ± 9.6°, p < 0.01). At multivariate analysis SPA and maternal age were identified as independent predictors of the mode of delivery. On the other hand, the duration of labor did not show a significant relationship with SPA. Conclusions: In low-risk nulliparous women at term gestation, SPA measurement obtained by 3D ultrasound before the onset of labor seems to predict the likelihood of an obstetric intervention but not the duration of labor.

“…In most patients this warping is rather minor and unlikely to introduce a clinically relevant error. The range of measurements suggests that the arbitrarily defined box depth of 1–2 cm described for the simplified method or VCI (thick slice) imaging of 1–2‐cm thickness will encompass the entire plane of minimal dimensions even in patients with the most marked degree of hiatal warping seen in this study.…”

“…The original method for the assessment of hiatal dimensions relied on identifying a single axial plane of minimal hiatal dimensions, assuming that this plane is flat. Both measurement of hiatal dimensions and volume acquisition have been shown to be highly repeatable, by us and by other groups. However, it has since become apparent that the true plane of the levator hiatus is not flat or Euclidean, but is in fact warped.…”
