To retrospectively evaluate the frequency of blunt cerebrovascular injury (BCVI) in patients with multiple trauma and to retrospectively compare the diagnostic accuracy of duplex Doppler ultrasonography (US) and computed tomographic (CT) angiography by using clinical follow-up and subsequent imaging as reference standards. ⋯ Injuries to the cervical arteries among blunt trauma patients are more common than previously reported. Duplex Doppler US has inadequate sensitivity to help rule out this condition. The notable morbidity with missed dissections warrants routine contrast material-enhanced studies of the carotid and vertebral vessels if patients are scheduled for CT of the cervical spine.
