Denver screening criteria
From WikEM
Background
- Used to screen for vertebral and carotid artery dissection and/or injury after blunt head and neck trauma (BCVI - blunt cerebrovascular injury)[1][2]
- A CTA to evaluate for VAI should be obtained in those meeting the modified Denver Criteria
- BCVI has the highest association with cervical hyperextension and rotation, hyperflexion, or direct blunt force to head and neck[3]
- Most injuries are diagnosed after the development of symptoms secondary to central nervous system ischemia resulting in neurologic morbidity of up to 80% and associated mortality of up to 40%.[4]
Criteria
The Denver Screening Criteria are divided into risk factors and signs and symptoms
Signs and Symptoms
- Focal neurologic deficit
- Arterial Hemorrhage
- Cervical Bruit or Thrill (<50yo)
- Infarct on Head CT
- Expanding Neck Hematoma
- Neuro exam inconsistent with Head CT
Risk Factors
- Midface Fractures
- Cervical Spine Injuries
- Basilar Skull Fracture
- GCS<8
- Hanging with Anoxic Brain Injury
- Seat belt abrasion or other soft tissue injury of the anterior neck resulting in significant swelling or altered mental status
