MRA scan showed right vertebral artery much smaller than left. Is this a problem? I get a lot of migraines and pain in right carotid and vertebral art

1 doctor agrees

In brief: Not at all

Not unusual to have asymmetric size of vertebral arteries, and this is merely an anatomic variant, having NOTHING TO DO with your migraines.
