Cerebral vascular bypass surgery after life, must be based on the specific situation for specific judgment, because cerebral vascular bypass surgery is only the way of treatment, to determine how much life, according to the original disease and thus decided, because most of the cerebral vascular bypass surgery are blood vessels have a certain amount of occlusive changes, cerebral infarction of the most patients, depending on the cerebral infarction of the specific corresponding changes in the condition. If belongs to the large cerebral infarction, and frequent attacks, no significant treatment, later without the corresponding rehabilitation, it is possible to exist only 2-3 years. If the patient is well taken care of under certain circumstances, with timely checkups and regular rehabilitation, he/she may survive for 5 or even 10 years in the later stage. In some cases, because the brain tumor encircles the blood vessels, thus taking vascular bypass surgery treatment, this time depends on the factors of the brain tumor, if it is a benign tumor, it is possible that it will not have an impact on the life after surgical resection, sometimes it may be a malignant tumor, and after resection, taking vascular anastomosis, it is possible that it can survive for 3-6 months, according to the specific circumstances of the decision.
