A member asked:

What is hypoplastic right vertebral artery?

A doctor has provided 1 answer

Normal variant: Hypoplastic right vertebral artery implies that this artery is very small and its function is taken over by the left vertebral artery. This is a normal variant and does not cause any problems unless you develop significant blockage in the left vertebral artery such as happens with vertebral artery dissection.
