The blockage of left cerebral blood vessel, asymptomatic small blood vessel blockage or fine blood vessel blockage does not need treatment, other blood vessel blockage needs timely treatment, common methods include thrombolytic therapy, mechanical embolism, cerebral artery bypass surgery, etc. 1, thrombolytic therapy: if the blocked blood vessel is the left middle cerebral artery, or the branch vessels of the anterior cerebral artery, thrombolytic therapy can be carried out, commonly used thrombolytic agents are alteplase, urokinase, this treatment needs to be carried out within 4 hours of the onset of the patient. This treatment needs to be performed within 4.5 hours of the onset of the disease. The advantage is that the sequelae of brain tissue damage and neurological deficits can be minimized. If the blocked vessel is the left internal carotid artery, middle cerebral artery or anterior cerebral artery, and the infarcted area of cerebral vessels is not large, mechanical embolization can be performed to save life. Bypass grafting. In daily life, patients should eat less fatty food to avoid increasing the risk of thrombosis.
