Abstract:
By means of Doppler ultrasound the blood velocity can be measured in the cerebral arteries in neonates and infants. In this article various modifications of the method are discussed. We conclude that for the time being the method of choice should be: measurement of absolute velocity in the internal carotid artery by use of transfontanellar duplex examination. The reliability of the method, the pathophysiological meaning of velocity curve parameters and the normal variation of the parameter values, are still a matter of debate.
