Lacunar infarction is a cerebrovascular disease. For lacunar infarctions caused by arteriosclerotic atherosclerosis, the main treatment is to prevent recurrence of infarction and dislodged plaques that cause blockages. Therefore, it is necessary to initiate treatments like aspirin, antiplatelet therapy, and atorvastatin to lower blood lipids and stabilize plaques. It is also important to control risk factors such as high blood pressure, diabetes, smoking, as well as conditions like hyperuricemia and hyperhomocysteinemia.
