There are individual differences in survival for conservative treatment of cerebral hemangiomas, related to whether they rupture or not and the amount of bleeding after rupture. Cerebral hemangioma is generally referred to as intracranial aneurysm, which is an abnormal protrusion of intracranial arterial vessels that often causes spontaneous subarachnoid hemorrhage, and its conservative treatment mainly consists of symptomatic administration of drugs to prevent and treat cerebral vasospasm. If it does not cause rupture and bleeding, it is usually asymptomatic and most can survive for a long time. If ruptured hemorrhage occurs, the patient may have severe headache, nausea, vomiting and even impaired consciousness. If the bleeding is small, the prognosis is generally good after timely symptomatic supportive treatment and usually does not affect the survival time; when the bleeding is large, the prognosis is relatively poor and the survival period may be only a few days to a month or so. Conservative treatment is usually not effective, and it is recommended to consider surgery as soon as possible. During the treatment period, it is necessary to maintain an optimistic attitude and avoid emotional excitement; ensure sufficient nutritional intake and regular rest and rest; actively cooperate with the treatment, take medication on time and review regularly.
