| Abstract: | Vertigo or dizziness in aged persons is sometimes induced by vertebro-
basilar insufficiency (VBI). Assessment of basilar artery (BA) hemodynamics is crucial to
predict this state. For this purpose, we have examined the mean blood flow velocity (FV),
Foulier pulsatility index (FPI) and C02 reactivity of BA by transcranial Doppler ultrasono-
graphy (TCD) in 48 patients suffering from vertigo with VBI. Twenty-four patients with
peripheral vertigo and 19 normal subjects were also subjected to this study as control
groups.
As a result, FPI proportionally related to the age of patients with VBI, while FV and CO2
reactivity did not show such a relationship. FV in VBI patients was significantly lower than
that in normal subjects. In addition, FPI and C02 reactivity in VBI were significantly
distinguishable from those in normal subjects and the patients with peripheral vertigo.
These findings demonstrate that TCD is a convenient and useful tool to evaluate the
insufficiency of cerebral circulation in vertigo patients. |
