Vertebral artery insufficiency. Coloured 3D computed tomography (CT) angiogram of the head and neck of a 58-year-old patient with a possible insufficiency (narrowing, upper centre) of the left vertebral artery (right) just below where the two vertebral arteries (yellow, left and right) join to become the basilar artery (yellow, top). Arterial insufficiency is a narrowing of the artery.
