After cerebral vascular bypass surgery, you can usually be discharged from the hospital in 7 days, but it must also be based on the specific conditions of the specific judgment. The most common type of vascular bypass surgery is superficial temporal artery and middle cerebral artery vascular bypass surgery, which is relatively less traumatic, faster anastomosis, and quicker postoperative recovery. However, attention must be paid because this kind of surgery, after all, has to open the cranium, and must be observed for 7 days. 1, observe the blood pressure. 2, observe the body temperature. 3, observe whether there is any limb dysfunction. If these are no problem, 7 days can be discharged. However, for other types of cerebral arterial bypass grafting, such as occipital artery, vertebral artery bypass grafting surgery is relatively more complex, because it involves the posterior occipital region, sometimes it even takes 2 weeks to be discharged from the hospital, and if the complications of intracranial hemorrhage, intracranial infections, it is important to improve the symptoms of this area, before deciding whether or not to be discharged home.
