Abstract

The purpose of this study was to determine regional cerebral flow velocity waveforms in the human fetus. Flow velocity waveforms were determined at the level of the middle cerebral artery, vertebral artery, and intracerebellar arteries in 25 fetuses between 23 and 39 weeks' gestation. The pulsatility index was used to quantify the waveforms. Technically acceptable waveforms were obtained at all three vessels in 20 fetuses. The pulsatility index was lowest for the intracerebellar artery in all the fetuses studied. The pulsatility indices of the vertebral artery and middle cerebral artery were not significantly different. These data suggest that significant fetal regional cerebral blood flow differences occur in utero, with intracerebellar arterial resistance being lower than resistance in other regions of the brain.
