What usually happens if you slip into a coma after a brain aneurysm? - what is aneurysm in french language

My mother had put on a brain aneurysm on Monday night, then went into a coma Wednesday. A coma was induced or not. No body really tell me what happened. Is this serious?

I asked a while ago, and almost no answers.
