Silent Stroke and Carotid Stenosis Stroke 23:483-485, Norris,J.W.&Zhu,C.Z., 1992 See this aricle in Pubmed Article Abstract Lesions seen on CT scan were most common in the transient ischemic attack with carotid stenosis group(47%)compared with the other groups(30%,19%)(p< 0.001).Cerebral infarcts ipsilateral to the carotid stenosis were found in 10%of patients with mild(35-50%)stenosis,17%in moderate(50-75%)stenosis, and 30%with severe(>75%)carotid stenosis(p<0.001).In patients with asymptomatic carotid stenosis,68%of infarcts were ipsilateral to the stenosis;in those with transient ischemic attacks and carotid stenosis,86% of infarcts were ipsilateral to the stenosis.Conclusions:The more severe the carotid stenosis,the higher the incidence of cerebral infarction ipsilateral to the stenosis.This finding applied to central infarcts as well as to peripheral infarcts in both symptomatic and asymptomatic patients.Silent cerebral infarction may be an indication for carotid endarterectomy in asymptomatic patients.
