Classification of Cerebral Artery Occlusion

Intracranial Model (placed in acrylic platform)

1. Internal carotid artery occlusion syndrome: vision loss or blindness, transient amaurosis, Homer syndrome; Contralateral hemiplegia and cortical sensory disturbance; Involvement of the dominant hemisphere may result in aphasia, alexia, and agnosia.

2. Middle cerebral artery: there were typical "three bias signs", that is, contralateral hemiplegia, hemisensory disturbance and hemiblindness in the same direction, and dominant hemispheric lesions with aphasia.

3. Anterior cerebral artery: contralateral central facial and lingual paralysis; Hemiplegia of lower extremity over upper extremity; Contralateral foot, calf movement and sensory disorders; Dysuria; May have strong grip, sucking reflex, mental disorders.

4. Posterior cerebral artery: contralateral hemianopsia and thalamic syndrome. The dominant hemisphere is involved, dyslexia, dyslexia, apraxia and agnosia.

5. Vertebrobasilar artery: sudden dizziness, vomiting, ataxia. And quickly appear coma, facial paralysis, quadriplegia, decerebral tonic, eyeball fixation, pupil shrinkage, high fever. Death can result from respiratory and circulatory failure.

6. Posterior inferior cerebellar artery or vertebral artery:

① dorsolateral bulbar syndrome: sudden dizziness, vomiting, nystagmus; Dysphagia, dysphagia, ataxia, Horner sign; Loss of pain and temperature sensation of contralateral trunk;

② ventral midbrain syndrome: oculomotor nerve palsy on the affected side, hemiplegia on the contralateral side;

③ Ventrolateral pontine syndrome: abducens nerve and facial nerve paralysis on the affected side, hemiplegia on the contralateral side;

④ Lock-in syndrome: clear consciousness, quadriplegia, unable to speak and swallow.

7. cerebellar infarction: often vertigo, nausea, vomiting, nystagmus, ataxia.

8. Lacunar syndrome:

(1) Pure motor hemiplegia is mainly characterized by complete or incomplete paralysis of the face, shoulder and leg on the same side, without other missing signs, and no lethargy at any time during stroke;

(2) The main manifestations of pure sensory stroke are hemisensory hypoesthesia or paresthesia;

(3) Hemisensory disturbance combined with hemiplegia in sensorimotor stroke;

(4) Ataxic hemiplegia may include ipsilateral ataxia - foot palsy syndrome or dysarthria - clumsy hand syndrome.
