Association between cervical spine and skull-base XXXX and blunt cerebrovascular injury.

INTRODUCTION: Blunt @entity130 (BCVI) are associated with high morbidity and mortality and can lead to @entity51 . The established criteria for @entity1 undergoing CT angiography (CTA) for BCVI are broad, and can expose @entity1 to radiation unnecessarily. This study aimed to examine the prevalence of BCVI in @entity1 on CTA and determine presentations associated with the highest rates of BCVI. MATERIALS AND METHODS: With IRB approval, @entity1 were selected for CTA screening for BCVI according to a predefined set of criteria at our hospital between 2007 and 2010. @entity1 were identified from our institution's @entity130 database. CTAs were retrospectively reviewed for BCVI including @entity2553 and dissection. Electronic medical records were reviewed for clinical presentation and hospital course. RESULTS: Of 432 @entity1 , @entity2553 (n   =   10) and/or dissection (n   =   36) were found in 46 @entity1 (10.6  %). BCVI was associated with cervical spine and/or skull-base @entity174 in 40/46 @entity1 (87  %, P   <   0.0001). Significant correlations were seen between dissection and @entity174 in 31/36 @entity1 (86.2  %, p   <   0.0001) and between BCVI and both @entity51 and @entity174 (27/44, P   <   0.0001). CONCLUSION: BCVI was significantly associated with cervical and/or skullbase @entity174 and @entity51 with coexistent @entity174 . @entity1 with these injuries should be prioritized for rapid CTA evaluation for BCVI. KEY POINTS:     CTA screening is important to identify @entity1 with underlying BCVI     Cervical spine and/or skullbase @entity174 were significantly associated with BCVI     BCVI may occur in up to 11  % of @entity1 with blunt @entity130 .
