Some of the complications that can result from an aneurysm rupture are:
· Re-bleeding: A ruptured or leaking aneurysm is likely to bleed again causing further damage to brain cells.
· Vasospasm: Rupturing of a brain aneurysm can lead to narrowing of the blood vessels in the brain, a condition called vasospasm. This can limit blood flow to the brain cells and damage them.
· Hydrocephalus: Hydrocephalus is caused when an excess of cerebrospinal fluid exerts pressure on the brain and damages the tissues. This condition occurs when an aneurysm ruptures and bleeds in the space between the brain and surrounding tissues (subarachnoid haemorrhage).
