Hello, She probably had the aneurysm for a long time that steadily became larger and one day burst open causing bleeding inside her brain. The recovery after treating a ruptured aneurysm depends on the amount of bleeding that has already taken place and the patient s condition at the time of admission. For example a patient with just headache will recover quicker that a patient in coma and unarousable. If she was unconscious when she was admitted and had a big bleed, then the recovery can be long and can leave residual neurodeficit if the patient survives. I hope this helps you understand.
