Clinical Features and Vascular Territories of Stroke Anterior circulation—anterior cerebral artery (ACA) - Contralateral leg weakness Anterior circulation—middle cerebral artery (MCA) - Contralateral face, arm > leg weakness, sensory loss, field cut, aphasia (left MCA) or neglect, apraxia (right MCA) Subcortical circulation deep penetrating branches of MCA - Contralateral motor or sensory deficit without cortical signs Posterior circulation—posterior cerebral artery (PCA) - Contralateral field cut Posterior circulation—brainstem, vertebral, or basilar artery branches - Dysphagia, dysarthria, tongue/palate deviation and/or ataxia with crossed sensory/motor deficits ( = ipsilateral face with contralateral body) Posterior circulation—basilar artery - Oculomotor deficits and/or ataxia with crossed sensory/motor deficits #Territories #Stroke #CVA #Diagnosis #Neurology
