title: [Blood flow in the umbilical artery in physiological pregnancy].
abstract: Fetal umbilical artery flow was measured with Doppler ultrasound technique in 206 cases of the uncomplicated pregnancy. Indices A/B and R.I. were calculated. It was shown that vascular resistance in the umbilical artery is decreasing in the normal pregnancy parallel to its development and is manifested by the changes in A/B and R.I. values.
