- Foundation
- From the basilar artery
- as a result of
- Occipital cortex occlusion
- Illness
- Extrapyramidal symptoms
- Posterior cerebral artery: from the basilar artery
- Cortical branches supply occipital lobe and temporal lobe
- Deep perforating branches supply the brainstem, thalamus, hippocampus, geniculate body

- Occlusion of the occipital cortex during occlusion, with contralateral hemianopia (macular avoidance); occlusion of the central branch can cause thalamus infarction, manifested as thalamic syndrome: contralateral lateral sensation loss, paresthesia and thalamic pain and extrapyramidal symptoms .
- Trunk occlusion causes contralateral isotropic blindness, severe upper visual field damage, and macular vision is not affected (the macular visual cortex represents the dual blood supply to the middle and posterior arteries of the brain). The midbrain level was occluded at the beginning of the posterior cerebral arteries, showing vertical gaze paralysis, oculomotor nerve palsy, nuclear piece paralysis, and vertical twisted strabismus. Involvement of the dominant hemisphere occipital lobe can cause named aphasia, aphasia, and aphasia. Cortical blindness, impaired memory (involving the temporal lobe) due to bilateral posterior cerebral artery occlusion, and inability to recognize familiar faces (face misrecognition), hallucinations, and behavioral syndromes. Deep perforator occlusion: thalamic penetrating artery produces red nuclear thalamus syndrome: cerebellar ataxia on the diseased side, intentional tremor, dance-like involuntary movement, and contralateral sensory disturbance; thalamus knee arteries appear thalamic syndrome: contralateral Deep sensory disorders, spontaneous pain, hypersensitivity, hemiplegia, ataxia, and choreography.
