This study was performed to clarify the hemodynamic of vertebral and common carotid arteries of normal subjects by ultrasonic doppler method. Subjects were 51 in all, i. e.,41males and 10 females, between 22 and 64 years old.
For the vertebral artery, mean blood velocity (BV) was 9.4± 3.5 cm/s, mean blood flow volume (BF) was 1.6 ± 0.6 ml/s and mean vessel diameter (VD) was 4.6 -± 0.5 mm. On the other hand, for the common carotid arteries, BV was 31.5±55.2.2 cm/s, BF was 14.0±3.2 ml/s and VD was 7.5 -±0.6 mm. BV of the vertebral arteries increased in the elderly, whereas BV of the common carotid arteries decreased in the elderly.
