Artery | Presentation |
---|---|
Left internal carotid artery | Right face/arm/leg weakness; left gaze deviation; aphasia (typically global) |
Right internal carotid artery | Left face/arm/leg weakness; right gaze deviation; neglect of left side |
Left middle cerebral artery | Aphasia; right face, arm > leg weakness; right sensory loss; left gaze deviation |
Right middle cerebral artery | Neglect of left side; left face, arm > leg weakness; right gaze deviation; anosognosia; agitation |
Anterior cerebral artery | Contralateral leg weakness; abulia; occasionally can present with bilateral leg weakness |
Posterior cerebral artery | Contralateral homonymous hemianopsia; contralateral sensory loss |
Posterior inferior cerebellar artery | Vertigo, nausea, hiccups, headache, direction-changing nystagmus Dysarthria, ipsilateral deviation of tongue “Crossed” motor deficits: ipsilateral facial and contralateral limb/trunk numbness Horner syndrome (ptosis, miosis, anhidrosis) |
Anterior inferior cerebellar artery | Ataxia; contralateral weakness/numbness; acute hearing loss |
Superior cerebellar artery | Ataxic gait; vertigo; nystagmus, dysarthria |
Basilar artery and basilar perforators | Locked-in syndrome: quadriplegia with preserved consciousness, preserved vertical eye movements and blinking |
