What is dominant vertebral artery?

Vertebral artery dominance, brainstem auditory evoked potential, and vertigo of vascular origin. Abstract. Objective: Vertebral artery dominance (VAD) is defined when there is a significant difference between the diameters of the vertebral arteries (VAs). VAD may be a risk factor for vertigo of vascular origin.
