vertebrobasilar TIA
Last reviewed 01/2018
Vertebro-basilar artery TIA's - account for about 7% of TIAs - clinical features are more diverse than those that may occur in carotid artery TIA's:
- commonly vertigo, diplopia, dysarthria, and weakness or sensory disturbance affecting one or other, or both, limbs
- less commonly, impairment of vision, dysphagia
- rarely, transient global amnesia, confusion, transient unconsciousness and hearing impairment
- note that isolated symptoms should not be diagnosed as a vertebro-basilar artery TIA unless accompanied by other symptoms suggestive of a transient brain stem disturbance
