Vertebrobasilar insufficiency classification
Introduction
Overview
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]
