A subarachnoid haemorrhage occurs when a aneurysm is located in the blood vessel between the brain and the skull bursts open and releases blood into the space between the brain and the skull (SAH). Within the first 14 days after the initial bleed, there is a 22% chance of bleeding again. As a result, surgery must be scheduled within 72 hours following the initial bleed or as early as possible.
