Cerebral infarction is a very common clinical cerebrovascular disease. Most cerebral infarctions are related to long-term atherosclerosis, arterial stenosis or elevated blood viscosity, which leads to thrombosis, and may also be related to long-term blood pressure and elevated blood lipids. Atrial fibrillation patients with dislodged emboli or diabetic patients with poor blood sugar control may also have cerebrovascular infarction as a complication. Patients with cerebral infarction usually experience dizziness, headache, hemiparesis of one limb, limitation of movement, numbness, nausea, vomiting, unsteady gait, fainting or coma. Determining brain infarction should be based on the size and location of the infarct as well as the length of onset to choose the most reasonable treatment method. If it is within 3-6 hours, thrombolytic therapy can be done with drugs such as urokinase, which is more effective, and infusion of drugs such as thromboxane and hemosiderin can also be applied, together with nerve-nourishing drugs.
