Cavernous cerebral ischemic foci generally refers to cavernous cerebral infarction. Cavernous cerebral infarction is related to the lesions of small arteries in the brain and other factors, which may cause headache, hemiparesis, limb weakness and other symptoms, and the patients’ prognosis is better after relevant treatment. Cavernous cerebral infarction is a type of small artery occlusive cerebral infarction, the main cause of the disease is related to the lesion of small arteries in the brain, if the lesion of the small blood vessels are narrowed, the blood flow can be reduced, and when thrombus is formed or there is a tiny embolus dislodged leading to blockage, it can ultimately result in ischemic infarction of brain tissue. Patients may experience symptoms such as headache, hemiparesis, limb weakness, and swallowing disorders. Patients can take thrombolytic therapy under the guidance of doctors, such as recombinant tissue-type fibrinogen activator or antiplatelet drugs, such as aspirin and clopidogrel. Or intravenous neuroprotective drugs, such as edaravone and cytarabine. Most patients have a good prognosis and can improve survival therapy. Once diagnosed with lacunar cerebral infarction, patients need to actively cooperate with doctors to take relevant treatment measures to avoid delays.
