Patients with aneurysmal SAH, in clinical grades I to III, should be operated upon, as soon as possible, irrespective of the time since ictus. Delay in definitive surgical treatment after admission to a neurosurgical unit, can lead to death from rebleeding in an additional 8.4% of patients, who are in a stable neurological state. This additional mortality can be reduced if facilities for emergency cerebral angiogram, optimal theatre facilities and neuroanaesthesia backup are available, coupled with surgeon's willingness, expertise and capability to give equally good results while operating on an aneurysm at odd hours.
