Angiographic classification of nonacute carotid artery occlusion to predict the feasibility and clinical outcomes of endovascular recanalization.
OBJECTIVE Endovascular treatment of nonacute symptomatic carotid artery occlusion (NASCAO) remains a technical challenge. The heterogeneity of a successful recanalization rate has limited its clinical efficacy. The aim of this study was to introduce an angiographic classification to determine the feasibility and clinic...
