Luminal foci in the basal ganglia region are not severe and are caused by occlusion of small arteries in the brain. The common etiology is hypertension, which leads to lesions in the vessel wall and eventual narrowing and occlusion of the lumen, resulting in lack of brain tissue and ischemic microinfarcts. The basal ganglia region is the favored site for cavity infarcts due to hypertension, and there will be no serious clinical symptoms, no serious problems such as unfavorable limb movement, hemiplegia, or speech clumsiness. Dizziness and headache may also occur if small infarcts occur repeatedly. There is no way to recanalize the infarcted area, and after treatment it is possible to prevent recurrent infarcts and improve symptoms. When lacunar cerebral infarction occurs in the basal ganglia region, it is necessary to control the risk factors of cerebrovascular disease, actively initiate the secondary prevention of cerebrovascular disease, keep the blood pressure within a reasonable range, and oral aspirin should be taken to prevent cerebral infarction by antiplatelet aggregation.
