Aneurysmal subarachnoid hemorrhage: management strategies and clinical outcomes in a regional neuroscience center.

Background And Purpose: Aneurysmal subarachnoid hemorrhage (SAH) affects six to eight people per 100,000 annually, yet the optimum management of this condition remains controversial. Although the International Subarachnoid Aneurysm Trial (ISAT) explored this area, only 28% of patients from our center were randomized in that study. Our purpose was to evaluate the treatment and outcomes of patients not recruited into ISAT.
