The second recurrence of cerebral infarction and the first fa have different clinical symptoms due to different lesion sites, mainly black haze, coma and even death in severe cases.
1. Internal carotid artery occlusion: when the internal carotid artery ischemia, the patient may have transient black haze in one eye, and occasionally permanent blindness.
2. Middle cerebral artery occlusion:
(1) Occlusion of the main trunk: it mainly leads to the symptoms of triple hemiplegia, i.e. hemiparesis, hemiplegia, hemianopsia and hemianopsia on the side opposite to the lesion, which may be accompanied by double gaze to the side of the lesion and impaired consciousness, etc. In the case of large cerebral infarction with severe cerebral edema, it may lead to cerebral herniation, or even death.
(2) Cortical branch occlusion: upper branch occlusion can lead to paralysis of the side opposite to the lesion, paralysis of the upper and lower limbs and sensory loss, which is usually not accompanied by impaired consciousness, while occlusion of the lower branch seldom occurs alone, which can lead to isotropic visual field defects on the opposite side.
3. Occlusion of the anterior cerebral artery:
(1) Occlusion of the cortical branch: it can lead to contralateral central lower limb paralysis and may be accompanied by sensory deficits.
(2) Occlusion of the trunk of the anterior communicating artery: it can lead to paraplegia of both lower limbs, incontinence, motor aphasia, etc. In addition, there are other secondary cerebral infarcts.
In addition, there are other symptoms of second relapse of cerebral infarction, which may be the aggravation of the original symptoms or the emergence of new symptoms. It is recommended that patients with cerebral infarction actively cooperate with the doctor’s treatment, regularly go to the hospital for rechecking, and immediately seek medical treatment if there is any discomfort.
