Does the 'high risk' patient with asymptomatic carotid stenosis really exist? 2008

Recent evidence indicates that the risk of stroke symptoms in non-operated medically managed patients with asymptomatic severe carotid stenosis has fallen significantly over the last 25 years. This suggests concurrent improvements in vascular disease medical intervention efficacy. If the latest estimates of average annual stroke rate for non-operated patients are reflective of contemporary medical intervention and surgical stroke/death rates match those of the randomised trials, the current implication is that carotid surgery will not offer a stroke prevention advantage over medical intervention alone. Furthermore, it is still not possible to identify patients with asymptomatic severe carotid stenosis with a higher than average ipsilateral stroke risk despite current medical intervention. Even if such patients were one day reliably identified, they could also be at higher risk of stroke/death from instrumental intervention (surgery, angioplasty or stenting) and randomised trials will be required before being justification in routine clinical practice.

D016893 Carotid Stenosis Narrowing or stricture of any part of the CAROTID ARTERIES, most often due to atherosclerotic plaque formation. Ulcerations may form in atherosclerotic plaques and induce THROMBUS formation. Platelet or cholesterol emboli may arise from stenotic carotid lesions and induce a TRANSIENT ISCHEMIC ATTACK; CEREBROVASCULAR ACCIDENT; or temporary blindness (AMAUROSIS FUGAX).

D020521 Stroke A group of pathological conditions characterized by sudden, non-convulsive loss of neurological function due to BRAIN ISCHEMIA or INTRACRANIAL HEMORRHAGES. Stroke is classified by the type of tissue NECROSIS, such as the anatomic location, vasculature involved, etiology, age of the affected individual, and hemorrhagic vs. non-hemorrhagic nature.
