Zhao Guangyu, Department of Neurosurgery, Shandong Provincial Hospital: Cerebral infarction is a common cerebrovascular disease, mostly caused by hypertension, diabetes, hyperlipidemia and other diseases that cause atherosclerosis, resulting in narrowing of the blood vessels, embolism, or embolism dislodgement, and this disease can recur. If possible, cerebral angiography can be done to implant stents in the narrowed vessels to prevent further cerebral infarction.
