Endovascular treatment for symptomatic vasospasm following traumatic brain injury: illustrative case

Fluctuations in consciousness or neuropsychological symptoms after TBI should prompt evaluation for CV using perfusion imaging, even in the absence of focal neurological deficits. When a high risk of severe vasospasm accompanied by perfusion reduction is identified, prompt, stepwise therapeutic intervention should be implemented, beginning with the least invasive treatment option to optimize clinical outcomes. https://thejns.org/doi/abs/10.3171/CASE25943.
