A 72-year-old man has been referred to the TIA clinic with a history of sudden-onset neurological disturbance, which resolved after 30 minutes. He reports that yesterday he had an episode of slurred speech and clumsiness of his right hand whilst he was eating breakfast. His wife reports that, at times, it was as though he could not see her. He has a history of hypertension and diabetes mellitus but is usually well. Neurological examination is normal. He undergoes an MRI and also undergoes carotid Doppler studies which demonstrate 60% carotid stenosis on the left and 40% stenosis on the right (NASCET criteria). He is commenced on antiplatelet and statin therapy. What would the most appropriate additional intervention be?
