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.

Feature	Denver Criteria	Memphis Criteria	Simplified Criteria
Primary Focus	Risk factors + Physical exam	Fracture patterns	Cervical spine focus
Sensitivity	High (approx. 90-95%)	Moderate (70-85%)	Variable
Inclusion of C-Spine	Extensive (C1-C3 + foramen)	C1-C3 only	Subluxation focus
Clinical utility	Gold Standard for Screening	Historical reference	Rapid bedside use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.
