Left hemi-oval center lacunar cerebral infarction is a lacunar cerebral infarction. The severity of lacunar cerebral infarction is related to the patient’s symptoms as well as the progression of the disease. Cavernous cerebral infarction is an ischemic infarction that occurs in the deep penetrating arteries of the brain, and most often occurs in the presence of underlying diseases such as hypertension and diabetes mellitus. If the condition of patients with lacunar cerebral infarction is mild, with only symptoms such as dizziness and headache, they can be treated with medications such as aspirin tablets and atorvastatin, and undergo regular checkups, the prognosis is usually better. If the condition of patients with lacunar cerebral infarction is more serious, with symptoms such as limb numbness, limb movement disorder, memory loss, etc., the condition is usually more serious, and drugs such as recombinant tissue-type fibrinolytic plasminogen activator can be used for intravenous thrombolysis within the thrombolytic time window, and drugs such as aspirin and clopidogrel can be used for treatment, and the prognosis is better for some of the patients with active treatment. It is recommended that patients with left hemi-oval center lacunar cerebral infarction should be treated under doctor’s guidance in time.
