An updated review of current concepts in the management of carotid stenosis

Several large randomized clinical trials in North America and Europe concluded over a decade ago that carotid endarterectomy plus medical management was significantly better than medical management alone for stroke prevention in either symptomatic or asymptomatic patients with severe carotid stenosis. Percutaneous carotid angioplasty now represents yet another treatment option that currently appears to have a higher risk than endarterectomy in symptomatic patients as well as in those who are 70 years of age or older. For these reasons, there is a consensus that angioplasty should be used cautiously in such patients and probably remains most appropriate either in the context of ongoing randomized trials or for patients who are at a higher-than-average risk for conventional surgical treatment.
