Carotid and vertebral artery injury following severe head or cervical spine trauma.

In order to determine the frequency of neck vessel injuries, Doppler investigations were performed in 60 patients following either severe head injury (n = 29), cervical spine injury (n = 26), or combined head and cervical spine injury (n = 5). The majority of patients were referred to our hospital for early rehabilitation; before admission Doppler investigations had been performed in only 2 patients. Clinically, 3 patients sustained severe cerebral ischemia due to neck vessel trauma: 1 patient with left-sided ICA dissection after head trauma revealed Doppler abnormalities only in the early phase of the disease; the second patient demonstrated persistent Doppler abnormalities due to traumatic right-sided ICA and VA occlusion. The third patient sustained a fatal vertebral and basilar artery thrombosis following cervical spine injury. In 57 patients without clinical signs suspicious of neck vessel trauma, sonography revealed abnormalities in 3 patients (11%) with severe head injury and in 6 patients (20%) with cervical spine or combined head and spine injury, in both groups mainly related to the vertebrobasilar system. Neck vessel injury is probably an underdiagnosed complication of severe head or cervical spine trauma. Although interpretation of Doppler findings may be difficult, particularly in the vertebrobasilar system, Doppler investigations can be recommended as a screening method to exclude neck vessel injuries.
