In 69 healthy volunteers (34 males, 35 females, age range 17-80 years) we compared the following haemodynamic parameters between the basilar artery and carotid artery system, assessed by transcranial Doppler sonography: mean blood velocity, pulsatility index and the hemispheric indices as ratios of the middle, anterior and posterior cerebral arteries with the internal carotid artery (MCA/ICA, ACA/ICA, PCA/ICA) and of the PCA with the basilar artery (PCA/BA), as well as the ACA/MCA and the MCA/BA ratio. In all arteries (ICA, MCA, ACA, PCA and BA) mean blood velocity decreased significantly with advancing age (p < 0.01) and was significantly higher in females as compared to males (p < 0.05). The pulsatility index increased significantly with age in the ICA, MCA, ACA and BA (p < 0.01) and showed no sex differences in any of the intracranial arteries except for the ACA. The MCA/ICA and ACA/ICA index declined significantly with advancing age (p < 0.005, p < 0.05, respectively) and with increasing heart rate (p < 0.01 for both arteries), while the ACA/MCA, the PCA/BA and the MCA/BA ratio remained unchanged by age and heart rate. We conclude that there is no striking difference in the cerebral haemodynamics of the basilar artery and the carotid artery supplied territories.
