Early Carotid Endarterectomy after Stroke

Abstract

The authors sought to determine if patients with stroke and a high-grade carotid stenosis benefited from a delay before carotid endarterectomy. A retrospective study of 45 patients undergoing carotid endarterectomy after stroke is presented. The patients were divided into two groups: group I (early group, n = 20), composed of patients who had carotid endarterectomy less than 6 weeks after stroke, and group II (late group, n = 25), comprised of patients who had carotid endarterectomy more than 6 weeks after stroke. As assessed by cerebral angiography, 100% of patients in group I and 64% of patients in group II had carotid artery stenoses > 76% (P < 0.001). The median interval from stroke to carotid endarterectomy was 14 days in group I and 129 days in group II. There was no mortality in either group. No patients in either group demonstrated any neurological deterioration. The authors conclude that, in select patients, carotid endarterectomy may be done safely less than 6 weeks after stroke in order to avoid new events or carotid occlusion while awaiting surgery.
