Abstract FORTY-FIVE MEASUREMENTS of diameters of 12 human cerebral arteries were
performed during 10 craniotomies under moderate changes in mean blood pressure and …

Transcranial Doppler monitoring of the middle cerebral artery blood flow velocity was used
as an adjunct to routine methods of cerebral monitoring in a prospective study of 30 …

Blood flow velocity in the middle cerebral artery, determined by transcranial Doppler
ultrasonography, was monitored during 31 carotid endarterectomies. Electroencephalogram …

✓ Noninvasive transcranial Doppler recordings were correlated to the angiographic findings
in 77 patients with carotid artery disease. Stenoses reducing the luminal area of the internal …

✓ Clinical studies with transcranial Doppler suggest that the pulsatility of the flow velocity
(FV) waveform increases when the distal cerebrovascular resistance (CVR) increases. To …

Background Transcranial Doppler sonography is increasingly used to monitor changes in
cerebral perfusion intraoperatively. However, little information is available about the validity …

Transcranial pulsed Doppler ultrasound and spectral analysis were used to monitor blood
velocities in the middle cerebral artery of nineteen patients (mean age 61±9 years) during …

Cerebral artery blood velocity and regional blood flow (rCBF) were investigated in 17 normal
subjects. Blood velocity was measured with 2 MHz pulsed Doppler ultrasound in the …

✓ In this report the authors describe a noninvasive transcranial method of determining the
flow velocities in the basal cerebral arteries. Placement of the probe of a range-gated …

Observations on blood velocity in the middle cerebral artery using transcranial Doppler
ultrasound and on the ipsilateral internal carotid artery flow volume were obtained during …
