Abstract
Determine patient and injury characteristics predictive of vascular injury (VAI) in blunt cervical spine (BCS) trauma to identify high-risk patients and propose an alternative screening protocol.
Patients presenting between 2014 and 2018 with BCS injury and cervical spine CT imaging were included. Demographics and injury characteristics of BCS injuries were collected. Univariate and multivariate analyses to determine risk factors for VAI were performed. Once factors associated with greater odds of VAI were identified, this information was used to create an alternative protocol for indicating CTA in patients who sustained BCS injury.
A total of 475 patients were included. CTA of the neck was performed in 55.5% patients. In patients who received CTA, 18.2% had a contraindication to receiving anti-platelet therapy, and 25% were already receiving anti-coagulation therapy as an outpatient medication. VAI was found in 13.2% patients. In patients with VAI, 48.5% were already receiving anti-coagulation as outpatient medication. Acute kidney injury was found in 10.5% patients who had received CTA. Factors associated with greater odds of having VAI included transverse foramen involvement(p = 0.0001), subluxation/displacement/dislocation of fracture(p = 0.03), high energy mechanism(p = 0.02), SLIC score > 4(p = 0.04), and concomitant lumbar spine injury(p = 0.03). Using Modified Hawkeye Protocol, 40.2% of patients were indicated to receive a CTA, and 17 VAI were identified. Compared to Denver Criteria, CTAs were performed in 73 less patients(p = 0.04).
Updated protocols utilizing evidence-based clinical parameters to predict chance of VAI may avoid unnecessary advanced imaging and contrast load to patients in the setting of BCS trauma.
