Cerebrovascular interventional surgery is a new therapeutic tool since the 1990s, and with the maturation of this technology, the life expectancy of patients can be up to 20 years, but there are individual differences in survival time. In our center, the longest survival time after cerebrovascular stenting has been 15 years, and the patient is still alive, so there are individual differences in the life expectancy of the patients after the surgery. If the patient’s risk factors for cerebrovascular disease are well controlled after surgery, the longer he or she will live. If the patient’s risk factors are not well controlled, there is a possibility of recurrence and a risk of restenosis, which can lead to recurrence of cerebrovascular disease, death, and reduced life expectancy.
