Cerebral vasospasm following aneurysmal subarachnoid hemorrhage: the impact of cocaine use, Hunt-Hess grade, and other risk factors.

ABSTRACT:

Introduction

Cerebral vasospasm (CV) is a common complication following aneurysmal subarachnoid hemorrhage (aSAH) that contributes to significant morbidity and mortality. While numerous identified CV risk factors exist, illicit substance use's influence, particularly cocaine, remains controversial. This study aims to elucidate relationships between known risk factors and CV's incidence, severity, and refractoriness.

Methods

A retrospective chart review was conducted on all aSAH patients between 2014 and 2023 with inclusion criteria of confirmed aneurysms on digital subtraction angiography (DSA) and available urine drug screens (UDS). Demographic data, Hunt-Hess (HH), modified Fisher Scale (mFS), comorbidities, and vasospasm grades were collected. Outcomes, including vasospas
