Carotid ultrasound is one of several available methods for the detection of carotid stenosis in patients with a recent cerebrovascular event. For patients with symptomatic carotid stenosis, the delay to carotid revascularisation for symptomatic stenosis should be kept short; thus, the choice of method for the initial examination should be based on local availability. In addition to the degree of stenosis, plaque morphology assessed with carotid ultrasound and microembolization and cerebrovascular reactivity assessed with transcranial Doppler have a prognostic value. Transcranial Doppler can also be used in the acute phase to diagnose large vessel occlusion and enhance the effect of intravenous thromobolysis.
