Cerebral artery stenosis can significantly increase a patient’s risk of ischemic stroke. For cerebral atherosclerotic stenosis, medical treatment can slow down the progression and stabilize the plaque to some extent, but it is difficult to reduce the degree of stenosis significantly. Endovascular stenting has been rapidly implemented in China for its positive clinical efficacy. Not all patients with cerebrovascular stenosis require endovascular stenting. For whether to implement stenting, physicians will make a comprehensive analysis and make a judgment based on the cerebral blood flow condition of the patient with cerebrovascular stenosis, the characteristics of the condition, and the measurement of the benefits and risks of stenting for the patient. For patients with symptomatic moderate cerebrovascular stenosis, formal medical medication should be preferred, and endovascular stenting should be considered after medical treatment has failed. For cerebral artery stenosis that has never shown ischemic symptoms, angiography shows stenosis course <70%, stenting should not be used, but drug therapy; stenosis degree >70%, stenting can be chosen. The annual risk of stroke in asymptomatic intracranial artery stenosis is only 1-3%. The risk of stroke may also be further reduced with the best available pharmacological treatment. Blind stenting can only bring unnecessary financial burden and psychological stress to patients and their families, so stenting should be treated with caution.
