Description:

Background Population-based studies have estimated that ≈15% of ischemic strokes are caused by large vessel cerebrovascular disease. We determined the types of large vessel atherosclerosis responsible for ischemic strokes in a population-based stroke study. Methods Patients with first-ever or recurrent ischemic stroke in the Greater Cincinnati area were identified during 2005 at all local hospitals. Study physicians assigned ischemic stroke subtypes. Overall event rates and incidence rates for first-ever events were calculated and age, race, and sex-adjusted to the 2000 US population. Results There were 2204 ischemic strokes, including 365 strokes of large vessel subtype (16.6% of all ischemic strokes). Extracranial internal carotid artery stenosis was associated with 8.0% of all ischemic strokes, while extracranial internal carotid artery occlusion and intracranial atherosclerosis were each associated with 3.5% of strokes. The annual rate of first-ever and recurrent stroke attributed to extracranial internal carotid stenosis was 13.4 (11.4–15.4) per 100,000 persons. We conservatively estimate that ≈ 41,000 strokes may be attributed to extracranial internal carotid artery stenosis annually in the United States. Conclusions Large vessel atherosclerosis is an important cause of stroke, with extracranial internal carotid artery stenosis significantly more common than extracranial internal carotid artery occlusion or intracranial atherosclerotic disease.
