title: [Doppler sonography of the umbilical artery for evaluating the fetoplacental vascular tree: a prospective histologic comparison].
abstract: We compared the clinical data, Doppler sonographic results and histological placental findings of 252 patients prospectively. A normal flow velocity wave form may be related either to a normal placenta villous and vessel architecture or to an at least focal leason with compensatory angiosis and/or high placental weight, whereas in cases with missing compensation phenomenon the end-diastolic blood flow velocities in the umbilical arteries are reduced.
