Brain Aneurysm

Some possible complications include brain swelling, seizures, cerebral salt wasting, syndrome of inappropriate ADH secretion (SIADH), neurogenic pulmonary oedema (fluid in the lungs) and cardiac (heart) abnormalities. Any of these could prolong hospitalisation stay and complicate recovery. 

The recovery process following a ruptured aneurysm is different with every patient. It often depends on the amount of damage in the initial rupture. If the patient has severe damage from the beginning, prognosis is often guarded. On the other hand, if the initial damage is limited and the aneurysm is successfully secured, the chance of a good recovery is much higher. The recovery process, however, may take many months to a year or more. A younger and fitter individual will have a better chance of a good recovery as compared to an elderly and weaker individual.
