Intracranial aneurysm (cerebral aneurysm) is a major disease that endangers people’s health. Once ruptured, the mortality rate is extremely high, generally the mortality rate of initial bleeding reaches 30%, and the mortality rate of rebleeding is up to 80%, therefore, once a cerebral aneurysm is detected, especially a high-risk aneurysm, active surgical treatment, interventional embolization or craniotomy clamping is recommended. So, what should we pay attention to after aneurysm surgery, can we resume normal human activities, can we go to work, can we still smoke and drink? Cerebral aneurysm itself is a kind of hemorrhagic cerebrovascular disease, the surgery itself can minimize the chance of its rupture and bleeding, theoretically blood flow no longer flows into the aneurysm cavity, it will not bleed, but due to the defect of blood vessel wall structure at the aneurysm, under the long-term impact of blood flow, there is still the possibility of local aneurysm forming again, which is called recurrence, so it should be reviewed regularly after surgery. 1.In case of ruptured aneurysm, cranial CT should be reviewed after one month. hydrocephalus may occur after subarachnoid hemorrhage. 2.Patients with skull defect should consider skull repair surgery after 3~6 months. 3.The cerebrovascular DSA examination is generally reviewed for the first time in 3 months after surgery, and if there is no recurrence, the cerebrovascular CTA examination can be reviewed later (usually 6, 12 and 24 months after surgery). 4. Patients with hypertension should monitor blood pressure more closely. If the blood pressure fluctuates greatly, you should go to the hypertension clinic to adjust the medication in time. 5, maintain a good state of mind, avoid being too emotional or negative. Laughter, violent coughing and other situations that may increase intracranial pressure. 6.Keep the bowel movement smooth, supplemented with necessary laxative drugs if necessary. 7.Control the underlying diseases, such as diabetes and hyperlipidemia, eat a healthy diet, control smoking and limit alcohol. 8.If the function recovers well, normal life and work can be resumed after 3~6 months. However, you should avoid high-intensity work and bad living habits. 9.After craniotomy, MRI should be done according to the nature of the specific implant material. For the current intervention most of these materials are fully compatible with MRI (the best MRI field strength does not exceed 3.0T); in principle, for the implant material made of steel, is completely incompatible with MRI, is contraindicated!
