Title

Denver crietriacriteria for blunt cerebrovascular injury
Body
was changed:
The Denver criteria are a set of screening criteria for blunt cerebrovascular injury (BCVI) used to reduce the need for CT angiography and its associated radiation exposure.
The screening protocol criteria for1, 3 for BCVI are 1
Signs and symptoms include:
- Arterial hemorrhage
- Cervical bruit in patient < 50 years of age
- Expanding cervical hematoma
- Focal neurologic deficit
- Neurologic exam incongruous with head CT scan findings
- Stroke on secondary CT scan
Risk factors include high-energy transfer mechanism with:
- Le Fort fracture: type 2 or 3
- base of skull fractures involving the carotid canal
- diffuse axonal injury with a GCS < 6
-
cervical spine fractures that involve C1-3
and, and/or the transverse foramen - cervical spine subluxation
- near hanging with hypoxic-ischaemic brain injury
A negative Denver criteria screening excludes BCVI in 99.8% of patients 2.
