One hundred ninety vertiginous patients were examined by several equilibrium examinations, magnetic resonance imaging, and MR-angiography (MRA). MRA findings were classified into five categories as follows: C-I) total vertebrobasilar system (VBS) stenosis; C-II) total unilateral vertebral artery (VA) stenosis; C-III) partial unilateral VA stenosis; C-IV) severe displacement of the basilar artery (BA); C-V) normal. The displacement angle of the BA was measured on the MR-angiogram. The mean angle was 152.2±39.7 degrees. In this study, those cases with an abnormal displacement angle less than 112.5 degrees were classified as C-IV.<BR>In central vestibular disorders (CVD), MRA abnormalities (C-I-IV) were detected in 60 out of 110 patients (54.5%), and abnormalities in the OKP and/or ETT were demonstrated in these patients. In the cases of CVD, the incidences of hyperlipidemia and hypotension were higher than that of anemia. A risk factors with aging, the incidence of MRA abnormalities was higher and the number of patients with orthostatic hypotension, increased.
