Analysis of delayed cerebral ischemia incidence after treatment for aneurysmal subarachnoid hemorrhage in young adults: A cohort study

Abstract

Background: This study aimed to analyze the incidence of delayed cerebral ischemia (DCI) and outcome stratified by age in patients who suffered aneurysmal subarachnoid hemorrhage.

Methods: A cohort study with patients from Christ the Redeemer Hospital from 2014 to 2020, with 359 patients separated into 2 groups, 48 of them aged under 40 years and 311 aged 40 years or over.

Results: In patients under 40 years of age, DCI was found in 81.3%, while in patients aged 40 or over, it was 61.4%. A relative risk of 1.32 (confidence interval: 1.12-1.55), with P = 0.013. After multivariate assessment, patients aged under 40 years were found to have a 27-39% higher risk of presenting DCI.

Conclusion: We identified that age under 40 years is a risk factor for the occurrence of DCI.

Keywords: Cerebral ischemia; Intracerebral aneurysm; Intracranial vasospasm; Subarachnoid hemorrhage.
