Kinderklinik, Universität Erlangen Nürnberg.

In 121 prematurely born infants, newborn and older infants (age 1-30 days, weight at investigation 1070-3750 g) flow velocities in the anterior cerebral artery, the internal carotid artery and the basilar artery were measured. All investigations were performed by computerised pulsed Doppler sonography (Acuson 128), with a 5 MHz transducer. Maximal systolic, endsystolic, and end diastolic flow velocities were measured as well as the pulsatility index and the resistance index. The flow velocities showed a strong positive linear correlation with age. The pulsatility indices were independent of age. For all flow parameters normal values were estimated.
