Doppler ultrasound examination of the anterior cerebral arteries of normal newborn infants: the effect of postnatal age. 1985

L N Archer, and D H Evans, and M I Levene

Twenty-four normal term infants were examined by Doppler ultrasonography of the anterior cerebral arteries at least twice in the first 5 days of life. It was found by comparison with a duplex Doppler unit that the anterior cerebral arteries could be reliably insonated using a continuous wave Doppler ultrasound probe without the concomitant use of real time ultrasound sector scanning. It was shown that the pulsatility of the velocity waveform decreased and that diastolic frequency increased over the 5 days. The significance of, and possible mechanism for, this change is discussed.
