Carotid Artery Stenosis is a cause of TIA, stroke and monocular visual loss (Amarosis Fugax). Carotid stenosis can also less frequently cause painful ocular ischaemia.
See also the following professional guide to Carotid Artery Stenosis.
Dizziness and vertigo is not a vascular diagnosis; therefore there is no indication to perform a carotid duplex scan. See ‘Dizziness and Vertigo’ guidance on Remedy.
Carotid Artery Stenosis is normally diagnosed following a Stroke or TIA and these patients should be referred immediately via usual pathways. If carotid artery stenosis is then diagnosied then patients are referred onto the vascular team internally.
Asymptomatic disease may be found incidentally and referral is then only required if stenosis ≥70% and age ≤75 years and patient is otherwise in good health.
CVD risk factors should be addressed including:
Surgical treatment, if required, is normally Carotid Endarterectomy of Carotid Artery Stent (rarely).
Refer patients with asymptomatic disease if criteria are met to vascular via e-RS Triage service for a routine appointment.
