Cerebrovascular occlusion can be reopened, cerebrovascular occlusion, also known as cerebral thrombosis, refers to intracranial and extracranial supply to the brain arterial blood vessel wall pathologic changes, so that the blood flow is slowed down, the blood composition changes or the blood viscosity increases, and the formation of thrombus leads to vascular occlusion. Cerebrovascular occlusion can be caused by atherosclerosis, diabetes mellitus, hyperlipidemia, high blood pressure, clinical cerebrovascular occlusion recanalization there are three main methods: first, the use of aspirin, statin drugs, so that the thrombus formed in the cerebral blood vessels to dissolve; second, if the degree of cerebrovascular occlusion is too heavy, carotid endothelial debridement surgical treatment can be used to repair the occlusion of the more severe cerebral blood vessels, to achieve cerebrovascular occlusion recanalization purpose; Third, the treatment method is to place a vascular stent inside the re-stenotic blood vessel to enlarge the occluded cerebral blood vessel to achieve the therapeutic purpose, which is suitable for patients who do not tolerate or refuse the surgery.
