title: Influence of preoperative risk factors on outcome after carotid endarterectomy.
abstract: As supported by level 1 multicenter randomized trial data, carotid endarterectomy (CEA) has a very low risk of perioperative morbidity and excellent durability, and provides significant long-term reductions of the risk of stroke. At Ochsner, our 1.1% risk of major stroke or death after CEA (n=366) is a demonstration of the safety of this procedure in experienced hands. This treatment modality continues to be the gold standard for most patients with carotid artery occlusive disease. Almost half of these patients treated with CEA were considered "high-risk" as defined by ineligibility for past or present randomized carotid trials. Importantly, these "high-risk" patients had outcomes that were not statistically different from "low-risk" trial-eligible patients. Thus, evidence-based decision-making does not support the routine use of investigational carotid stenting in "high-risk" trial-ineligible patients. However, carotid stenting is clearly a valuable alternative for selected patients. Our challenge is to precisely define which patients will most benefit from medical, surgical, or catheter-based therapy for carotid artery occlusive disease.
