Infarction of the cerebellum and brainstem can be restored by means of active restoration of blood flow. Cerebral vascular blockage is caused by cerebral infarction due to a variety of reasons, and has its own developmental and evolutionary pattern. If the patient is given revascularization treatment during the acute phase, such as intravenous thrombolysis, to dissolve the thrombus blocking the blood vessels and achieve the purpose of saving brain tissue and brain nerve function, the patient’s cerebellum and brainstem infarction can be fully recovered without brain cell necrosis remaining. If the treatment in the hyperacute phase is missed, the patient may have some of the symptoms left behind, causing the patient to have neurological deficits. However, this is only the process of the disease, not the end of the disease, through other ways to try to save the patient’s brain tissue, preservation of neurological function, for the risk factors causing cerebral infarction prevention and treatment, can also achieve the goal of cure.
