In medicine, carotid endarterectomy, or CEA, is "excision of the thickened, atheromatous tunica intima of a carotid artery."[1] This is done to prevent a stroke.
Concomitant aspirin may decrease complications.[2][3]
Effectiveness
CEA can benefit patients with[4] and without[5] symptoms according to systematic reviews by the Cochrane Collaboration and the American Academy of Neurology[3].
Preoperative assessment
The preoperative care includes assessment for coronary heart disease. In one study, 40% of patients had coronary heart disease, with 18% of the patients (or 48% of those with coronary heart disease) had severe disease (obstruction of the left main or three of the arteries).[6] The strongest predictor of coronary heart disease was the presence of diabetes mellitus. The presence of bilateral carotid disease was not a significant prediction of coronary disease. The presence of cardiac symptoms probably increasess the likelihood of coronary disease.[7]
The role of coronary angiography[8] and coronary revascularization[9] are not established.
