The treatment of right vertebral artery ciliations should be judged according to its cause. There are physiological causes, so that no special treatment is needed and regular observation is possible. However, the common cause of vertebral artery slenderness is insufficient perfusion of the vertebral artery due to narrowing of the vertebral artery opening, resulting in vertebral artery slenderness. This narrowing of the opening is mostly due to narrowing of the vertebral artery opening formed by atherosclerosis, resulting in vertebral artery slenderness, which can cause posterior circulation ischemia and poor perfusion of the posterior circulation, resulting in cerebral infarction. Therefore, for patients with atherosclerosis causing vertebral artery stenosis and vertebral artery fibrillation, interventional treatment can be performed to implant a stent in the vertebral artery opening, which can improve the vertebral artery fibrillation, improve the blood supply to the vertebral artery and maintain the stability of the posterior circulation.
