, Annexe 4 : Score ASPECT Score de 10 points permettant d'évaluer les AVC ischémiques dans le territoire de l'artère cérébrale moyenne sur un scanner cérébral sans injection

, Divise le territoire de l'artère cérébrale moyenne (ACM) en 10 secteurs : Régions profondes ou sous-corticales (n=3) et régions superficielles ou corticales (n=7)

, Se calcule sur une TDM sans injection en coupe axiale : Absence d'hypodensité = 1 point Score=10 : absence totale d'hypodensité Score=0 : hypodensité de tout le territoire de l'ACM Les hypodensités doivent être visibles sur au moins deux coupes différentes adjacentes Un score ?7 est associé à un pronostic péjoratif tant en termes de handicap résiduel que de risque de transformation hémorragique
