If aneurysms cause symptoms, it is possible to tie them off using special clips. Clinicians also refer to this process as clipping. The procedure cuts off the aneurysm from the blood supply, preventing it from bleeding.

The operation is carried out using microsurgery and special monitoring. After treatment, the patient is looked after for 1-2 days on the intensive care unit. Where there is hydrocephalus following a subarachnoid haemorrhage, the cerebrospinal fluid may need to be re-routed (shunt). Cerebral bleeds which take up space in the brain are also treated.

The timing and nature of the procedure depend partly on the patient's condition.
