Gayani Jayasooriya, BSc, MBBS, Ankur Thapar, BSc, MBBS, MRCS, Joseph Shalhoub, BSc, MBBS, MRCS, Alun H. Davies, MA, DM, FRCS  Journal of Vascular Surgery  Volume 54, Issue 1, Pages (July 2011) DOI: /j.jvs Copyright © 2011 Society for Vascular Surgery Terms and Conditions

2 Fig 1 Preferred reporting items for systematic reviews and meta-analyses (PRISMA) flow chart. CEA, Carotid endarterectomy; MRI, magnetic resonance imaging; TCD, transcranial Doppler. Journal of Vascular Surgery  , DOI: ( /j.jvs ) Copyright © 2011 Society for Vascular Surgery Terms and Conditions

3 Fig 2 A, Graph demonstrating prevalence of transcranial Doppler (TCD) detected high intensity transient signals (HITS) in symptomatic and asymptomatic carotid stenosis. B, Frequency of TCD-detected HITS per hour in symptomatic and asymptomatic carotid stenosis.

4 Fig 3 A, Prevalence of transcranial Doppler (TCD) detected high intensity transient signals (HITS) in varying degrees of asymptomatic carotid stenosis. B, Prevalence of HITS in <70% and ≥70% asymptomatic stenosis. Journal of Vascular Surgery  , DOI: ( /j.jvs ) Copyright © 2011 Society for Vascular Surgery Terms and Conditions

5 Fig 4 A, Combined stroke and transient ischemic attack (TIA) risk in transcranial Doppler (TCD) emboli positive and negative subjects with asymptomatic carotid stenosis. B, Stroke risk in TCD emboli positive and negative subjects with asymptomatic carotid stenosis. HITS, High intensity transient signals.

6 Fig 5 Prevalence of silent cerebral infarctions (SCIs) on computed tomography (CT) scans in subjects with asymptomatic carotid stenosis. The prevalence of pattern A (nonlacunar discreet subcortical and cortical) infarcts is also demonstrated.
