Years ago, my aunt died fro an aneurysm. Back then, only a few aneurysms could be fixed. Hers wasn't one of them. She was discharged to my parents' care and told she could live another 30 years or go tomorrow.
Less than a week later, she suffered a fatal stroke.
Today more aneurysms can be successfully treated, although there are still significant risks of complications and death. I just wush these treatment were available when my aunt suffered a aneurysm. She might have lived longer.
