This study was performed to investigate the hemodynamics of the basilar artery (BA) of normal subjects and patients with vertigo by transcranial Doppler ultrasonography (TCD). There were 85 normal subjects, 50 males and 35 females, 23 to 83 years old (mean 50.0 years), and 74 patients with vertigo, 34 males and 40 females, 23 to 83 years old (mean 63.8 years).<BR>The mean blood flow velocity (FV) and Fourier pulsatility index (FPI) of the BA were measured by a midline approach.<BR>In normal subjects, FPI increased while FV did not change in the elderly. In patients with vertigo, FV decreased in 24 cases, FPI increased in 15 cases.<BR>Transcranial Doppler ultrasonographic evaluation is a feasible, noninvasive, reproducible technique that can detect abnormal hemodynamics in the BA.
