Timing of carotid endarterectomy in patients with recent stroke.

Abstract

There is little objective data to support the conventional wisdom of waiting 4 to 6 weeks after stroke to improve surgical outcome of subsequent carotid endarterectomy (CEA). We have aggressively pursued CEA in patients after recent stroke; in this study we report our results. We performed 215 CEA procedures in 200 patients who presented with an indication of stroke within 6 months of CEA. Cervical block anesthesia was used 193 cases. The rest were performed with the patient under general anesthesia. Perioperative stroke rate was 1.4% (3/215), and operative mortality was 2% (4/200) (stroke mortality = 3.4%). There were four early occlusions. Shunts were used in 13.9%, patch closure in 8.4%, and eversion endarterectomy in 48% of cases. There was no correlation between timing of surgery, extent of infarct on computed tomography/magnetic resonance imaging, and postoperative neurologic complications with the occurrence of postoperative stroke (p = NS). During the same period, 1,922 patients underwent CEA for indications other than stroke, with a perioperative stroke rate and mortality rate of 1.1%. Selected patients presenting with a history of stroke and significant carotid artery disease can safely undergo early CEA with a mortality and morbidity comparable to patients undergoing CEA for other indications.
