Cerebral infarction thrombus extraction should refer to the cerebral infarction artery thrombus extraction, thrombus extraction success can be restored to normal, but also can be left sequelae, need to actively cooperate with the rehabilitation exercise. Brain tissue is extremely sensitive to ischemia and hypoxia damage, blocking blood flow for 30 seconds, brain metabolism will change, ischemia for 1 minute neuron function activity stops, complete cerebral ischemia>5 minutes can lead to brain cell death. Brain cells are permanent cells, which cannot be regenerated after necrosis, therefore, even if the thrombus is successfully removed after cerebral infarction, some brain cells will be necrotic, and the symptoms of neurological impairment will remain, and it is necessary to actively cooperate with the rehabilitation treatment, and the symptoms can be restored after the rehabilitation treatment for mild cases, while the severe cases may have some after-effects. Patients with cerebral infarction are recommended to seek medical treatment in time to avoid adverse prognosis.
