- Abstract
- Rotational vertebral artery syndrome (RVAS)
is characterized by recurrent attacks of paroxysmal vertigo,
nystagmus, and ataxia induced by head rotation. Although
recent report has described the RVAS as an important but
unrecognized cause of isolated vascular vertigo, the locus
of injury site responsible for isolated vertigo in RVAS is
still unclear. We report here two patients with RVAS who
had a stereotypic clinical presentation characterized by
recurrent attacks of isolated vertigo induced by head rotation.
The pattern of nystagmus observed in our patients
with RVAS can be best explained by the stimulation of the
vestibular labyrinth bilaterally or unilaterally. In RVAS,
the isolated vertigo may occur due to transient ischemia of
the superior vestibular labyrinth. RAVS should be considered
in the differential diagnosis of positional vertigo,
especially when vertigo is developed while sitting or
standing position.
