Slowdown of the right posterior cerebral artery and bilateral basilar arteries is mainly considered to be related to cerebral stenosis and insufficient blood supply to the cerebral arteries. Treatment includes diet control, appropriate exercise, use of antiplatelet aggregating drugs, statins, Chinese patent medicines, and interventional therapy. 1. Diet control: When it is clear that there is insufficient blood supply to the brain, it is recommended that patients eat a low-salt, low-fat diet and eat more green vegetables and fruits. 2. Appropriate activities: daily aerobic activities, such as jogging, hiking, playing table tennis, etc., can control body weight and reduce blood lipids. 3. Antiplatelet aggregation: If patients are at risk of ischemic stroke, they should use antiplatelet aggregation drugs, such as aspirin and clopidogrel, under the guidance of doctors. 4. Statin drugs: such as Rosuvastatin, Atorvastatin, etc., have the effect of adjusting blood lipids and preventing ischemic stroke. 5. Proprietary Chinese medicines: representative medicines include Cerebroxin Tong, Ginkgo biloba extract, etc., which can activate blood circulation and eliminate blood stasis (promote blood circulation and eliminate blood stasis in the body) and improve circulation. 6. Interventional therapy: Interventional therapy can be given when cerebral angiography clearly shows that the stenosis of blood vessels is greater than 70%, or more than 50% and the patient has obvious symptoms. When the right posterior cerebral artery and bilateral basilar arteries are found to be slowing down, it is necessary to go to the Neurology Clinic in time, to clarify the cause of the disease under the guidance of the doctor, and to give symptomatic treatment.
