Transcranial Doppler sonography (TCD) is a useful diagnostic method to measure cerebral blood flow velocity in various cerebral disorders. However, we haven't data enough to be available for young persons, especially in the twenties in Korea. This study was performed to collect the basic data of the cerebral blood flow velocity and to understand the cerebral physiology in the twenties. We determined the mean velocities of middle, anterior, and posterior cerebral artery, and vertebral and basilar artery (MCA-V, ACA-V, PCA-V, VA-V, and BA-V, respectively) in eighty-two healthy volunteers. For evaluating cerebral autoregulation, only the MCA-V was measured under various conditions such as stable, apnea, and hyperventilation state. Right and left MCA-V were 80.66±14.03 and 83.22±14.40 ㎝/sec at stable state, 90.l3±17.47 and 90.26±16.38 ㎝/sec at apnea, and 54.83±11.09 and 55.33±10.74 ㎝/sec at hyperventilation. Right and left ACA-V were 49.11±15.71 and 48.19±13.75 ㎝/sec. Right and left PCA-V were 39.44±9.12 and 37.91±6.74 ㎝/sec. Right and left VA-V were 33.65±9.26 and 36.18±10.39 ㎝/sec. BA-V was 48.49±11.16 ㎝/sec. Right and left MCA-V, VA-V, and right ACA-V and PCA-V in women were higher than those of men (P<0.05). No significant differences were found between men and women in the others. These findings indicate that cerebral hemodynamics and autoregulation were normal in young people in their twenties. The velocities of MCA, ACA, PCA, and BA were high values in women as compared with men.
