Hemodynamic changes in patients with whiplash injury measured by transcranial Doppler

Transcranial Doppler (TCD) sonography with Transcan 3-D EME device and 2 MHz probe was used for the assessment of vertebrobasilar circulation in patients with whiplash injury of the cervical spine that occurred mostly in car accident. This study includes 47 patients with clinically verified cervical spine trauma with x-ray evidence of on bone lesion. The patients were examined by TCD within a month and then six months following the accident. The values obtained were compared with normal blood flow velocities and correlated with the severity of clinical picture. During the first month after the injury, statistically significant disturbances in the vertebrobasilar circulation were recorded; this is an increase in mean blood flow velocities in AVL (68%) AVR (62%) and BA (51%) mostly as spasm. Six months later, normal findings were obtained in about 50% of the vessels whereas in rest of the patients vasospasm persisted in one, two or all blood vessels.
