Abstract
Approximately 1 to 20% of the general adult population harbor a saccular cerebral aneurysm, which is an acquired lesion resulting from prolonged hemodynamic stress at unsupported bifurcations and angles in major cerebral arteries traversing the subarachnoid space. A more liberal application of computerized tomography (CT) in the investigation of unusual headaches could facilitate recognition of minor hemorrhages that frequently precede major, devastating aneurysm ruptures. Rebleeding is a major cause of death and disability in survivors of aneurysm rupture, and the rate of rebleeding is highest on the first 2 days following the initial hemorrhage. If treated with bed rest alone, approximately 20% of patients will rebleed within 14 days, 30% in 30 days, 40% in 180 days, and thereafter patients will continue to rebleed at the rate of about 3% per year.
