Cerebral blood supply insufficiency can be treated with medication, surgery, and interventional therapy. Insufficient cerebral blood supply is mostly related to the narrowing of the lumen of the carotid and vertebral basilar arteries due to atherosclerosis, which may lead to symptoms such as dizziness, vomiting, limb weakness and numbness. 1. Drug therapy: follow the doctor’s instructions to use anti-platelet aggregation, lipid-lowering drugs and drugs to improve cerebrovascular circulation, such as aspirin, atorvastatin, ginkgo biloba, nimodipine, which can prevent thrombosis, stabilize atherosclerotic plaques, dilate blood vessels, in order to improve the cerebral blood supply insufficiency. 2. Interventional therapy: Angioplasty and stent implantation are commonly used interventional therapies to improve the blood supply of narrowed blood vessels. 3. Surgery: For patients with severe stenosis or obvious symptoms of insufficient cerebral blood supply, carotid artery dissection can be performed. Patients with symptoms such as dizziness, vomiting, limb weakness, numbness, etc. should consult the doctor in time and standardize the diagnosis and treatment to avoid delaying the condition.
