Cerebellar ischemia in the acute phase, i.e., within 3-4.5 hours, can be considered for intravenous thrombolysis. If contraindications are ruled out and there are clear indications, intravenous thrombolytic therapy with alteplase can be considered. If a basilar artery macrovascular lesion spreading to the cerebellum is considered to be the cause of symptoms, thrombolysis can be considered within 24 hours after assessment of the ischemic semidarkhor band. Beyond the 24-hour window, antiplatelet and intensive statin therapy is usually used. Patients who continue to have high blood pressure after stabilization also require aggressive antihypertensive, risk factor control, and symptomatic treatment. After stabilization of the disease is still dizziness, walking instability, ataxia and other symptoms, the later stage of the balance function of rehabilitation training.
