Cerebral infarction is best treated by thrombolysis within 4.5 hours of the onset of the disease, and 14 days is the critical period for the treatment of cerebral infarction in patients who cannot be thrombolized in general. However, asymptomatic cavernous infarction is sometimes not easy to be detected, and if it is detected in the imaging examination, it also needs active and standardized treatment. Cavernous infarction refers to small perforating arteries deep in the cerebral hemispheres or brainstem, where lesions in the vessel wall occur on the basis of long-term hypertension, leading to occlusion of the lumen and the formation of small foci of infarction. Cavernous cerebral infarction usually does not have obvious headache or consciousness disorder, and mainly manifests as simple motor light hemiparesis, maloconstruence – hand clumsiness syndrome, etc.. The disease is often recurrent and can cause multiple cerebral infarcts, cognitive impairment and dementia. Significant improvement is usually seen after individualized treatment for the cause within 4.5 hours of onset. Cavernous cerebral infarction generally has a good prognosis, but is prone to recurrent attacks, so it is necessary to prevent recurrence of the disease.
