BackgroundThe incidence of traumatic craniocervical artery dissection varies in published trauma series.ObjectiveTo determine the frequency of traumatic craniocervical artery injury in polytrauma patients by using standardized whole-body trauma computed tomography with adapted computed tomography angiography of the craniocervical vessels.MethodsA total of 718 consecutive patients requiring whole-body trauma computed tomography (16-row multislice) because of the mechanism of their injury patterns and an Injury Severity Scale score greater than 16 were analyzed prospectively. After a cranial scan, computed tomography angiography of the craniocervical vessels with 40 mL of iodinated contrast agent was performed using bolus tracking.ResultsThe overall incidence of blunt carotid and vertebral injuries (BCVIs) in the screened population was 1.7%. BCVIs were observed in 27.3% of patients with detected isolated cervical spine injuries and in 3.9% of patients with isolated cranial fractures with or without intracranial hemorrhage, whereas 5.3% of patients with combined cervical and cranial lesions were associated with BCVIs. In addition, 0.4% of BCVIs occurred in patients without evidence of head or neck trauma.ConclusionWhole-body trauma computed tomography with an adapted scanning protocol for the craniocervical vessels is a fast, safe, and feasible method for detecting vascular injuries. It allows prompt further treatment if necessary. Computed tomography angiography could be a part of a broad screening protocol for craniocervical vessels in documented injuries of the head and neck and in trauma mechanisms influencing the craniocervical region as well.
