Patients with cerebral vascular stenosis need long-term medication, because narrowed cerebral blood vessels are mainly caused by cerebral atherosclerosis.1 If the degree of stenosis is relatively heavy, it is easy to lead to the patient’s blood platelets in the middle section of the blood adhesion and aggregation, which is easy to form a cerebral thrombus in the stenosis site, and ultimately lead to the patient’s cerebral blood vessels occluded, and the patient develops acute cerebral vascular disease. Therefore, patients with cerebrovascular stenosis need to take long-term oral anti-platelet aggregation of Bayer Aspirin or oral Polivir, which mainly prevents thrombosis as well as restenosis of the diseased blood vessels, as well as oral anticoagulant drugs, such as warfarin and heparin.2 If the degree of stenosis of the patient is more severe, such as 70%-99% stenosis, stenting can be chosen for treatment on the basis of assessing the benefits and risks of the patient. The stenting option is available for patients with severe stenosis, such as 70%-99%.
