What usually happens if you slip into a coma after having a brain aneurysm?

Need more details: Thats a complex question. Need more details. Is there an associated in the brain? Has the aneurysm been repaired? Is there increased intracranial pressure? Sometimes aneurysms are something a patient can recover from, even if ruptured. Though with limited information, this is hard to say.

Varies: Even if a patient has a coma after an aneurysm rupture, they have a chance of recovery. It depends on the interventions that are taken by the neurosurgeon to reverse the cause of the coma. Frequently, there is excess pressure from hydrocephalus that is readily reversed. If the coma is because of damage to the brainstem, then the prognosis is not as good.
