How common are saccular aneurysms?
Super-giant aneurysms (>50 mm) are rarely encountered. The annual risk of hemorrhage is estimated at 2%, assuming an incidence of SAH of 10 per 100,000 per year and a maximum prevalence of rupture of 0.5% in unruptured aneurysms. Two or more aneurysms may be discovered in 15% to 25% of patients.
