Common treatments for basilar artery stenosis include atorvastatin and other medications as prescribed by the doctor, and interventional therapy if necessary, and the best method is long-term medication maintenance therapy after intervention. Basilar artery stenosis is mainly caused by atheromatous plaque formation, which is formed by lipid deposition after endothelial damage. Interventional treatment with stent placement can directly improve carotid artery stenosis and improve blood supply to brain tissue. Postoperative medication is often used to lower blood lipids with statins (e.g., simvastatin, atorvastatin, etc.) to prevent in-stent thrombosis. It should be noted that for patients with severe stenosis of the basilar artery, due to the weakness of the blood vessels, it is also necessary to comprehensively assess the risk of interventional therapy and choose a safe and effective surgical method.
