The symptomatic carotid plaque.
BACKGROUND The natural histories of equally severe symptomatic and asymptomatic carotid stenoses are very different, which suggests dichotomy in plaque behavior. The vascular biology of the symptomatic carotid plaque is presented in this review. SUMMARY OF REVIEW Histology studies comparing asymptomatic and symptomatic plaques were identified from MEDLINE. Reports in which stenosis severity w...
متن کاملHistological features of symptomatic carotid plaques in relation to age and smoking: the oxford plaque study.
BACKGROUND AND PURPOSE Rates of incident and recurrent cardiovascular events rise steadily with age, due partly to more extensive atherosclerotic burden. However, in patients with similarly severe symptomatic carotid stenosis, increasing age is associated with a greater risk of ipsilateral ischemic stroke. This effect may be due to age-related differences in the pathology of symptomatic carotid...
متن کاملSymptomatic ulcerative carotid plaque.
A 65-year-old man with a history of smoking, hypertension, and diabetes mellitus presented because of sudden-onset left hemiparesis. On admission, neurological examination disclosed a mild left-sided weakness, a normal consciousness level, and a right carotid bruit. The blood pressure, ECG, echocardiogram, and laboratory studies were all unremarkable. He was taking daily aspirin, enalapril, and...
متن کاملQuantitative assessment of carotid plaque surface irregularities and correlation to cerebrovascular symptoms
BACKGROUND The purpose of this study was to determine whether surface irregularities measured from ultrasound images of carotid artery plaques and quantified using a novel method, correlate with the presence of ipsilateral hemispheric cerebrovascular symptoms. METHODS A plaque surface irregularity index (SII) was measured in 47 carotid artery plaques (32 subjects, stenosis range 10% -95%, 49%...
متن کاملCritical cap thickness and rupture in symptomatic carotid plaques: the oxford plaque study.
BACKGROUND AND PURPOSE Advances in carotid plaque imaging could allow quantification of fibrous cap thickness in vivo. While a cap thickness <65 microm is the accepted definition of rupture-prone plaque in the coronary circulation, the threshold value for carotid plaques is unknown. METHODS We made detailed histological assessments of 526 carotid plaques from consecutive patients undergoing e...
