Expanded Denver Criteria (BCVI screening)
Denver blunt-cerebrovascular-injury screening criteria: whether any sign or risk factor is present that warrants CT-angiography screening for BCVI.

Example
- Expanding cervical hematoma
- Yes
Result: 1 criterion positive (Expanding cervical hematoma): CT angiography screening for BCVI is indicated.
The tool opens with these values already filled in. Replace them with your own.
What you enter
- Arterial hemorrhage from neck/nose/mouth
- Cervical bruit (age < 50)
- Expanding cervical hematoma
- Focal neurologic deficit
- Neurologic deficit incongruous with CT
- Stroke on CT/MRI
- Le Fort II or III fracture
- Cervical-spine fracture
The other 4 fields
- Basilar skull fracture involving the carotid canal
- Diffuse axonal injury with GCS < 6
- Near-hanging with anoxic brain injury
- Seatbelt sign / soft-tissue neck injury
How this is calculated
- Rule
- CT angiography screening for blunt cerebrovascular injury is indicated if ANY sign/symptom or high-energy-mechanism risk factor is present.
- Items
- 6 signs/symptoms (hemorrhage, bruit < 50, expanding hematoma, focal deficit, exam-CT mismatch, stroke) plus 6 risk factors (LeFort, cervical-spine, carotid-canal, DAI, near-hanging, seatbelt).
