Modified Memphis criteria for blunt cerebrovascular injury

Last revised by Rohit Sharma on 4 Apr 2024

The modified Memphis criteria are a set of screening criteria for blunt cerebrovascular injury (BCVI) in trauma. 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:

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 concluded that CTA should be performed on all multi-trauma patients for 37.5% of injuries would have been missed 3.
