The vertebral arteries usually arise from the posterosuperior aspect of the central subclavian arteries on each side of the body, [2] then enter deep to the transverse process at the level of the 6th cervical vertebrae (C6), [1] or occasionally (in 7.5% of cases) at the level of C7.
Rotational vertebral artery syndrome (sometimes referred to as Bow Hunter's Syndrome) results from vertebral artery compression on rotating the neck. [7] The commonest cause is a bone spur from a cervical vertebra , in combination with disease in the opposite vertebral artery.
