title: Carotid endarterectomy under cervical plexus block--a prospective clinical audit.
abstract: One hundred and twenty-eight patients having carotid endarterectomy under superficial and deep cervical plexus blocks were prospectively audited. The aim of the audit was to determine the incidence of intra-operative and postoperative neurological and cardiovascular complications and to establish patient acceptance of the technique. Twenty-seven patients who had intra-operative neurological changes following carotid artery clamping responded to shunt insertion. Six patients had transient neurological changes after the operation but there were no permanent neurological complications. Tachycardia (55%) and hypertension (67%) were the most common intra-operative cardiovascular changes and there was one clinical postoperative myocardial infarction. Ninety-two per cent of patients who could be adequately assessed preferred to have the same method of anaesthesia for future carotid endarterectomy. The authors concluded that carotid endarterectomy under superficial and deep cervical plexus blocks was associated with a high patient acceptance, low neurological complication rate and an acceptable rate of cardiovascular complications.
