Abstract
Management of patients with asymptomatic carotid artery stenosis post CREST-2. *CEA is preferred over OMT if carotid stenosis progression, silent embolic infarcts on brain imaging, detection of microemboli on transcranial Doppler, plaque echolucency on Duplex ultrasound, carotid plaque ulceration, intraplaque haemorrhage on magnetic resonance angiography or decreased cerebrovascular reserve. CAS, carotid artery stenting; CEA, carotid endarterectomy; CREST-2, Carotid Revascularization and Medical Management for Asymptomatic Carotid Stenosis Trials; CTA, computed tomography angiography; DUS, duplex ultrasound; OMT, optimal medical treatment; MRA, magnetic resonance angiography.
