Most patients with brain aneurysms can act like normal people after cure, but some patients who have already suffered bleeding may develop complications such as seizures or hydrocephalus. For cerebral aneurysms that have not ruptured, after surgical treatment (e.g., cranial aneurysm clamping or minimally invasive interventional embolization), patients can usually return to normal after surgery if no serious complications occur. For cerebral aneurysms that have ruptured, it is also possible to return to normal after surgical treatment and active postoperative rehabilitation. However, if the amount of bleeding is large and the surgery cannot completely remove the hematoma, the hematoma will compress the brain tissue as well as produce toxic effects, and the patient may suffer from epilepsy, hydrocephalus and other related complications after the surgery. Patients with cerebral aneurysm should pay attention to controlling blood pressure, maintaining emotional stability, avoiding smoking and alcohol, paying attention to rest, etc., and consulting the doctor in time if any abnormality occurs.
