Carotid angioplasty: Is it safe?

For 15 years, balloon angioplasty has been cautiously applied to carotid artery occlusive lesions. Procedural results have, by and large, been satisfactory, but the potential for significant neurologic complications and a dearth of controlled studies with long-term follow-up have impeded the development of carotid angioplasty until recently. This review of the literature chronicles the slow but steady evolutionary pace of carotid angioplasty from its beginnings in 1980 to today's shifting focus to the use of stents. Based on these existing reports and significant personal experience, the advantages and risks of endoluminal carotid interventions are enumerated, along with suggested criteria for the application of carotid angioplasty.
