The sequelae of craniotomy for cerebral aneurysm must be judged according to the actual situation. The biggest case is the sequelae of headache, dizziness, nausea and vomiting, and some people may have hemiplegia, speech dysfunction and other sequelae such as convulsions due to cerebral infarction at a later stage. However, the sequelae can be improved through corresponding treatment, such as internal medicine to improve cerebral circulation, brain protection, and corresponding functional rehabilitation exercises. The most fearful sequelae are the vegetative state formed after aneurysm craniotomy. Although the patient may not be able to guarantee survival completely, the life activities will be greatly affected, which will cause great impact on individuals and families, and there is no special effective way to cure it, so this aspect is very serious.
