1 mar 2022 · Vertebrobasilar insufficiency (VBI) occurs when blood flow to the back of your brain lessens or ends. This part of your brain controls movement and balance, so VBI can lead to difficulty swallowing, dizziness and numbness. Hardening of your arteries (atherosclerosis) usually causes VBI.
Symptoms of Vertebral Artery Stenosis. A vertebrobasilar stroke classically causes vertigo, ataxia and loss of balance. Various cranial nerves can be dysfunctional. Breathing and consciousness may be impaired. One should differentiate this type of stroke from subclavian steal syndrome. Another group of symptoms are ‘low flow’ symptoms.

Symptoms of carotid artery stenosis include ipsilateral transient visual obscuration (amaurosis fugax) from retinal ischemia; contralateral weakness or numbness of an arm, a leg, or the face, or of a combination of these sites; visual field defect; dysarthria; and, in the case of dominant (usually left) hemisphere involvement, aphasia.
