Modified Memphis criteria for blunt cerebrovascular injury
Updates to Article Attributes
The modified Memphis criteria are a set of screening criteria for blunt cerebrovascular injury (BCVI). The presence of one or more of these criteria makes necessary a complementary CTA or DSA study to exclude a BCVI.
The screening protocol criteria for BCVI are:
- base of skull fracture with involvement of the carotid canal
- base of skull fracture with involvement of petrous temporal bone
- cervical spine fracture
- neurological exam findings not explained by neuroimaging
- Horner syndrome
- Le Fort II or III fracture pattern
- neck soft tissue injury (e.g. seatbelt sign, hanging, hematoma)
Ciapetti et al. showed that a modification of the original Memphis criteria could increase the sensitivity of BCVI 1. If a trauma patient meets one or many of these criteria, the diagnosis of BCVI should be excluded with CTA or DSA. DSA is far more sensitive than 32-MDCT 2 but less available. However, a study retrospectively applying the criteria has recently concluded that CTA should be performed on all multi trauma-trauma patients asfor 37.5% of injuries would have been missed 3.
