Cerebellar infarction is an infarction of the posterior circulation, and the disease is still relatively severe. If the site and extent of cerebellar infarction are large, it may cause severe edema in the brain tissue, resulting in pressure in the fourth ventricle, causing obstructive hydrocephalus, and the patient’s intracranial pressure increases, which may endanger the patient’s life, so this is a serious case and may require surgery to decompress or control the intracranial pressure through extraventricular drainage to save the patient’s life. If the infarct is not large, the patient may have headache, nausea, vomiting, vertigo and unsteadiness, dysarthria and other problems, so treatment should be actively carried out. If the patient is seen early in the acute phase, he can be treated by thrombolysis or, depending on the cause, anticoagulation, neuroprotection, fibrin-lowering or antiplatelet aggregation.
