Vascular injury outcomes with screening implementation

Abstract

Abstract Blunt carotid and vertebral artery injuries (BCVI) are generally viewed as rare events. Screening guidelines based on the Memphis and Denver data were put into place at Palmetto Health Richland in August of 2008. This study aims to look at the incidence of BCVI 2 years before the guidelines were put into place and then 2 years after. A total of 11,005 trauma patients presented during our study period. 98 patients were determined to have BCVI and met inclusion criteria: 21 in the Control group and 77 in the Screening group. A total of 16 deaths and 14 strokes were recorded in the study population. The odds of patients in the Screening group dying were 29% lower than that of a patient in the Control group [OR: 0.71, (95% CI: 0.20–2.50); p = 0.59], after adjusting for ISS. The odds of developing a stroke in the Screening group were 69% lower than the Control group [OR: 0.31 (0.09–1.08); p = 0.067]. These differences were not statistically significant. The increased BCVI incidence rate and decreased stroke and mortality rate following screening implementation further support the importance of having screening criteria for blunt vascular injury following trauma.
