Infarct cerebral

necroza a unei parti mai mult sau mai putin importante a encefalului, legata de obstructia uneia din arterele care il iriga. Infarctul cerebral este forma cea mai grava a ischemiei cerebrale (micsorarea aporturilor sangvine arteriale la creier). Cauza cea mai frecvent constatata este o tromboza (obstructia cu un cheag sau trombus), favorizata de prezenta, in interiorul arterei, a unei placi de aterom (depunere de colesterol). O a doua cauza este embolia, migrarea unui fragment de trombus sau a unei placi de aterom situate in amonte, pe o artera (carotida sau aorta toracica) sau in inima.

simptome si semne -Acestea depind de teritoriul cerebral al necrozei, deci de artera implicata. Obstructia unei ramuri a carotidei interne provoaca o hemiplegie, uneori o afazie (tulburare de vorbire). Obstuctia unei ramuri a tunchiului bazilar (artera nascuta din reunirea a doua artere vertebrale, destinata partii posterioare a cerebelului) provoaca fie tulburari vizuale complexe (pierderea unei parti a campului vizual, tulburarea recunoasterii vizuale), fie un sindrom altern (hemiplegia uneia din parti, paralizia fetei de pe cealalta parte) sau un sindrom cerebelos si vestibular (tulburari ale coordonarii miscarilor, vertije).

Diagnostic si tratament -Diagnosticul se pune pe baza unei examinari scaner. Tratamentul, in faza acuta, este indeosebi cel al simptomelor: el vizeaza mentinerea functiilor vitale, evitarea extinderii leziunilor si complicatiilor legate de imobilizarea la pat. Pe termen lung, medicamentele anticoagulante sau antiagregante evita recidivele. Evolutia se face in mod obisnuit spre o recuperare treptata a deficitului sau deficitelor neurologice (motricitate, limbaj); recuperarea este ajutata prin adaptarea ei la fiecare caz.

Sinonim: accident cerebral ischemic, ramolisment cerebral.
