Prognostic value of scales for aneurysmal subarachnoid hemorrhage: Report of a reference center in Peru.

Introduction: Multiple scales have been designed to stratify the severity and predict the prognosis in the initial evaluation of patients with aneurysmal subarachnoid hemorrhage (aSAH). Our study aimed to validate the most commonly used prognostic scales for aSAH in our population: Hunt-Hess, modified Hunt-Hess, World Federation of Neurosurgical Societies (WFNS), Prognosis on Admission of Aneurysmal Subarachnoid Hemorrhage (PAASH), and Barrow Aneurysm Institute (BAI) scales.

Methods: This study includes all aSAH cases treated at our institution between June 2019 and December 2020.
