Though occlusion of this major artery can have devastating effects, no part of the brain is dependent solely on the internal carotid from one side.Abdominal Aorta Stenosis Symptoms. Complications After Stent Surgery. Ischemic strokes are due to hypoperfusion from arterial occlusion, or less commonly due to decreased flow resulting from proximal arterial stenosis andThe common ocular symptoms associated with extracranial carotid artery occlusive disease include amaurosis fugax and presence of Hollenhorst Both stenosis and occlusion of the common or internal carotid arteries are responsible for ipsilateral ocular signs and symptoms that may herald a devastating cerebral infarction (Biousse, 1997).

How to Improve Patient Selection? found an odds ratio of 14.4 of ipsilateral stroke and TIA in pa-tients with carotid occlusion and/or stenosis and ex-hausted reactivity. Carotid artery stenosis is a narrowing or constriction of any part of the carotid arteries, usually caused by atherosclerosis.
