Abstract
The incidence of spontaneous aneurismal subarachnoid hemorrhage is 6–10 per 100,000 patients per year, and the prevalence of intracranial aneurysms is between 1 and 5 % of the population. This suggests that 0.2–1 in 100 aneurysms rupture each year. One third of patients who have a subarachnoid hemorrhage will die before they get to a hospital, and another third will die within a month as a result of the damage done at the time of the bleed. Aneurismal rebleeding is the greatest risk to life. This has two peaks of increased risk: in the early and subacute phases within 24 h and at 7–10 days. If left unsecured, about 25 % will rebleed in the first 2 weeks and two-thirds within the first 2 months. Treatment options include supportive resuscitation, neurosurgical clipping, and endovascular therapy.
