We think this might be relevant to the clinical guidance for Expanded Denver Criteria (BCVI).

When to Use
Blunt Cerebrovascular Injury (BCVI) is a hidden but potentially devastating consequence of blunt trauma, often presenting with a latent period before the onset of ischemic stroke. The Expanded Denver Criteria provide a standardized screening protocol to identify asymptomatic patients who require CTA (Computed Tomography Angiography) to rule out carotid or vertebral artery injury.

Historical reference
Rapid bedside use
Approximately 20-30% of BCVI cases occur in patients who do NOT meet original screening criteria. The "Expanded" criteria were developed to capture these occult injuries.
Related Scores in Practice
In clinical practice, this assessment is frequently evaluated alongside other validated measures. Depending on the patient's presentation and specific diagnostic requirements, you may also need to utilize the AAST Vascular Organ Injury Scale, Memphis Criteria, or the Biffl Grading Scale to formulate a comprehensive care plan.
