Anterior choroidal artery syndromes

摘要: Three cases of anterior choroidal artery territorial infarction, diagnosed by computerized tomography, with the triad hemiplegia, hemianaesthesia and hemianopia, pure motor stroke ataxic hemiparesis are described. Major minor (lacular) infarctions in territory involve almost exclusively basal segment posterior limb internal capsule manifest themselves symptoms long pathway lesion. Based on published case reports authors' own observations, complete capsular syndrome characterized hemianopia was differentiated from partial syndromes including following forms: stroke, sensory sensorimotor hemiataxia, hemiparesis, dysarthria and/or clumsy hand, homonymous (quadrantanopia or sectoranopia). The characteristic features above types were analyzed. Distant involving transcortical aphasias construction apraxia dominant hemisphere, left side perception failure visual-construction non-dominant cerebellar hemiataxia. These distant a manifestation cortical metabolic depression due to mechanism diaschisis.
