What is ICA occlusion?

A complete occlusion of the internal carotid artery (ICA) is an important cause of cerebrovascular disease. A never‐symptomatic ICA occlusion has a relatively benign course, whereas symptomatic occlusion increases future risk of strokes.

Is an ICA occlusion a stroke?

Patients with TIAs or minor ischemic stroke who are found to have an ipsilateral occlusion of the ICA are at risk for further stroke and other vascular events….Selected Abbreviations and Acronyms.

What will happen if the internal carotid artery becomes occluded?

If an artery becomes completely blocked (which is called carotid occlusion) or if piece of the blockage breaks off and travels to a smaller vessel where it completely blocks blood flow, a part of the brain may be completely deprived of oxygen, leading to the destruction of brain tissue.

What is ICA treatment?

Purpose: Nonoperative treatment of recent internal carotid artery (ICA) occlusion is associated with increased recurrent stroke rates. We analyzed our results of carotid endarterectomy (CEA) for treatment of symptomatic recent ICA occlusion to evaluate its feasibility, safety, and outcomes.

What happens when carotid artery is blocked?

If the narrowing of the carotid arteries becomes severe enough that blood flow is blocked, it can cause a stroke. If a piece of plaque breaks off it can also block blood flow to the brain. This too can cause a stroke.

Can a 100% blocked carotid artery be unblocked?

The carotid arteries can be affected by atherosclerosis that can lead to progressive narrowing (stenosis) and, in some instances, complete blockage (occlusion). In most cases of complete carotid artery occlusion, attempting to reopen the blocked artery isn’t beneficial.
