RESUMO
BACKGROUND: It has been suggested that specific cervical spine fractures (CSfx) (location at upper cervical spine [CS], subluxation, or involvement of the transverse foramen) are predictive of blunt cerebrovascular injury (BCVI). We sought to determine the incidence of BCVI with CSfx in the absence of high-risk injury patterns. METHODS: We performed a retrospective study in patients with CSfx who underwent evaluation for BCVI. The presence of recognized CS risk factors for BCVI and other risk factors (Glasgow coma score ≤ 8, skull-based fracture, complex facial fractures, soft-tissue neck injury) were reviewed. Patients were divided into 2 groups based on the presence/absence of risk factors. RESULTS: A total of 260 patients had CSfx. When screened for high-risk pattern of injury for BCVI, 168 patients were identified and 13 had a BCVI (8%). The remaining 92 patients had isolated low CSfx (C4-C7) without other risk factors for BCVI. In this group, 2 patients were diagnosed with BCVI (2%). Failure to screen all patients with CSfx would have missed 2 of 15 BCVIs (13%). CONCLUSIONS: We propose that all CS fracture patterns warrant screening for BCVI.

BACKGROUND: Eastern Association for the Surgery of Trauma guideline for the evaluation of blunt cerebrovascular injury (BCVI) states that pediatric trauma patients should be evaluated using the same criteria as the adult population. The purpose of our study was to determine whether adult criteria translate to the pediatric population. METHODS: Retrospective evaluation was performed at a Level I trauma center of blunt pediatric trauma patients (age <15 years) presenting over a 5-year period. Data obtained included patient demographics, presence of adult risk factors for BCVI (Glasgow coma scale ≤8, skull base fracture, cervical spine fracture, complex facial fractures, and soft tissue injury to the neck), presence of signs/symptoms of BCVI, method of evaluation, treatment, and outcome. RESULTS: A total of 1,209 pediatric trauma patients were admitted during the study period. While 128 patients met criteria on retrospective review for evaluation based on Eastern Association for the Surgery of Trauma criteria, only 52 patients (42%) received subsequent radiographic evaluation. In all, 14 carotid artery or vertebral artery injuries were identified in 11 patients (all admissions, 0.9% incidence; all screened, 21% incidence). Adult risk factors were present in 91% of patients diagnosed with an injury. Major thoracic injury was found in 67% of patients with carotid artery injuries. Cervical spine fracture was found in 100% of patients with vertebral artery injuries. Stroke occurred in four patients (36%). Stroke rate after admission for untreated patients was 38% (3/8) versus 0.0% in those treated (0/2). Mortality was 27% because of concomitant severe traumatic brain injury. CONCLUSION: Risk factors for BCVI in the pediatric trauma patient appear to mimic those of the adult patient.
