Overview
There isn't classification about the VBI yet, but there are three phenotypes of the basilar artery occlusion depending on the modal of initial symptoms.
Classification
- phenotype 1: patients present progressive brain stemsymptoms(for example: vertigo, doublevision, dysarthria, hemiparesis, or paresthesia) without any prodromal symptoms.[1]
- phenotype 2: patients present nonspecific, such as nausea, tinnitus, hearing loss, and vertigo, which can precede the onset of the monophasic, progressive deficits by days, but typically by several weeks.[2][3]
- phenotype 3: patients present symptoms with onset of severe, often bilateral motor weakness, ophtalmoplegia, and coma. The patients may have a severe outcome if basilar artery cannot be recanalized fast.[1]
