Intra ‐placental arterial Doppler: A marker of fetoplacental vascularity in late‐onset placental disease?

ConclusionsMore vascular placentas ex vivo are associated with reduced intra ‐placental artery Doppler impedance in utero. Although umbilical (but not intra‐placental) artery Doppler PI is associated with adverse outcome after reduced fetal movement, this predictive ability does not appear to be through assessment of placental vascularity or chorionic plate arterial func tion. The inferior reliability of intra‐placental artery Doppler, although similar to previously published reliability of umbilical artery Doppler, impairs its ability to detect subtle differences in placental vascularity, and must be significantly improved before it could be considered a clinical ly useful test.
