Multiple Choice

Normal vertebral artery velocity range in most patients is:

Explanation:
In duplex assessment of the vertebral arteries, the velocity you expect to see in a healthy adult is in the midrange—approximately 45 to 60 cm/s. This reflects the VA’s smaller caliber and the posterior circulation’s typical flow characteristics, giving a moderate, steady peak velocity rather than the higher rates seen in larger carotid vessels. Velocities much lower than this can indicate reduced flow or occlusion, while markedly higher velocities suggest stenosis or hemodynamic change. Among the options, 45–60 cm/s best matches what is seen in most normal vertebral arteries, making it the best choice.
