Template:Denver screening criteria 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]
Algorithm for evaluation of BCVI with high risk criteria based on Memphis and Denver Screening Criteria
