Carotid endarterectomy. Controversies and recommendations.
Carotid endarterectomy is a comparatively safe procedure for prevention of stroke in carefully selected patients with carotid stenosis. Generally, it is indicated in patients with hemispheric symptoms of transient ischemic attacks (TIAs), but it is more controversial in patients with non-hemispheric TIA symptoms or no symptoms. Emergency endarterectomy in patients with acute TIA symptoms is considered dangerous. Results of a series of 120 endarterectomies performed at Straub Clinic, Honolulu, confirm the benefits of elective endarterectomy when a meticulous operative technique is followed and intraoperative angiography and repair of defects are done. Prophylactic endarterectomy should not be performed unless a very low incidence (less than or equal to 3%) of combined major morbidity and mortality can be achieved.
