Normal range for blood flow velocity in cerebral arteries of newly born term infants.
A cross-sectional study of 128 healthy full term infants was made using duplex Doppler ultrasonography in order to establish a normal range for cerebral blood flow velocity (CBFV) in the first week of life. Recordings were made from both the anterior (ACA) and middle cerebral arteries (MCA). There was a statistically significant increase in CBFV in both the ACA and MCA over the first four days of life, which was particularly obvious in the first 24 h. There is a close relationship between measurement of CBFV from the ACA and the MCA, although the velocity tends to be higher in the MCA.
