Abstract

Abstract only Introduction: Impact of race on outcomes in the treatment of intracranial aneurysm (IA) remains unclear. We aimed to investigate the relationship between race classified into White, Black, Hispanic, and other ("other" includes Native American or Alaska Native, Asian or Pacific Islander, and other race) and treatment outcomes in patients with ruptured and unruptured IAs. Methods: Stroke Thrombectomy and Aneurysm Registry (STAR) was a retrospective observational study. Data from 9 centers in the United States, Europe, and Asia for IA patients who undertook endovascular treatment (EVT) or microsurgical treatment (MST) between January 2016 and December 2020 were included for analysis. The primary outcome was 90-day mRS 0-2. Secondary outcomes included periprocedural cerebral infarction and intracranial hemorrhage, perioperative symptomatic cerebral vasospasm in ruptured IA and mortality, and all causes of mortality within 90 days. Results: 2,836 IA patients treated with EVT or MST were included. Among these 2,836 patients, 1,053 patients were White, 350 were Black, 264 were Hispanic, and 1,169 were other. The primary outcome in Hispanic patients was significantly lower than White patients (adjusted odds ratio [aOR] 0.36, 95% CI, 0.23-0.56, P < .001). The periprocedural cerebral infarction, perioperative mortality, and all causes of mortality in Hispanic patients were significantly higher than White patients (aOR 2.53, 95% CI, 1.40-4.58, P = .002, aOR 1.84, 95% CI, 1.00-3.38, P = .049, aOR 1.83, 95% CI, 1.06-3.17, P = .03, respectively). However, these outcomes were not significantly different in Black and other patients compared to White patients. Conclusions: This study demonstrates Hispanic IA patients are more likely to have a poor outcome at 90 days following EVT or MST than White patients.
