Stenting can be done for cerebrovascular disease, but before stenting, patients are recommended to have cerebral angiography to clarify the degree of stenosis and the degree of atherosclerotic plaque in the entire cerebrovascular course, and whether the patient has indications for stenting. In general, if the stenosis is above 75% and the blocked vessels are in several large arteries, only in this case is the patient recommended to undergo cerebrovascular stenting. For severe cerebrovascular stenosis, the effect of stenting is more certain, but after stenting, patients need to take long-term antiplatelet aggregation drugs, such as aspirin and clopidogrel hydrogen sulfate. Patients also need to control all high-risk factors to avoid further worsening of cerebrovascular blockage.
