How long does it take for a brain aneurysm to kill?

This isn't a cancer question, but I know a man had one and he pretty much died within minutes of it rupturing. I also know a woman, that didn't die after hers leaked and caused a stroke. Drs spent quite a while "chasing" it around, keeping it at bay until they found the source of the bleed. She's home now and doing well. So I can say it kills Suddenly
