Some 10% of patients with a symptomatic internal carotid artery stenosis greater than 70% suffer a stroke every year. Of these, approximately one-third die, one-third recover, and one-third suffer significant residual neurological impairment.1 Carotid endarterectomy (CEA) reduces the risk of stroke in such symptomatic patients,2 although not in those with lesser stenoses, or near-occluded carotid disease. Thus, rather like the management of hypertension, the operation does not cure the patient of their disease, but is performed to prevent a life-threatening complication. Additionally, the complication rate of the procedure is high, so the stakes are high and, perhaps more than many other procedures, clinicians involved in carotid surgery tend to have dogmatic views regarding the anaesthetic and surgical techniques they are prepared to use.
Whilst the primary indication for surgery is neurological symptoms, much of the morbidity and mortality of the operation is cardiovascular in origin. Overall, the incidence of serious
