Endarterectomy, although effective, does have limitations, and percutaneous techniques may offer an alternative method of treatment.\n          <\/jats:p>\n          <jats:p>\n            <jats:italic>Methods and Results<\/jats:italic>\n            The feasibility and safety of percutaneous carotid angioplasty and elective (primary) stenting was evaluated prospectively in a consecutive series of 107 patients. One hundred twenty-six carotid arteries with significant stenosis were treated. This series represented a high-risk subset that included patients with previous ipsilateral endarterectomy and severe medical comorbidity. Forty-five percent of the patients were referred by surgeons. Patients had independent neurological examinations before and after the procedure and follow-up cerebral angiography at 6 months. The mean (\u00b1SD) stenosis was reduced from 78\u00b114% to 2\u00b15%. There were 7 minor strokes, 2 major strokes, and 1 death during the initial hospitalization and first 30 days after the procedure. For the combined end point of all strokes and death, the incidence was 7.9%. For ipsilateral major stroke and death, the incidence was 1.6%. There were no strokes during the follow-up period. Mean angiographic stenosis at 6 months in 81 patients was 18\u00b116% (range, \u221221% to 57%). Four (4.9%) of these 81 patients had asymptomatic restenosis. Five asymptomatic patients had repeat intervention: 2 had angioplasty for restenosis, 2 had angioplasty for stent deformation, and 1 had endarterectomy for restenosis.\n          <\/jats:p>\n          <jats:p>\n            <jats:italic>Conclusions<\/jats:italic>\n            In a high-risk group of patients, percutaneous carotid angioplasty and stenting are feasible and can be performed with low restenosis and repeat intervention rates.\n          <\/jats:p>","DOI":"10.1161\/01.cir.95.2.376","type":"journal-article","created":{"date-parts":[[2012,6,12]],"date-time":"2012-06-12T00:41:02Z","timestamp":1339461662000},"page":"376-381","update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":527,"title":["Elective Stenting of the Extracranial Carotid Arteries"],"prefix":"10.1161","volume":"95","author":[{"given":"Jay S.","family":"Yadav","sequence":"first","affiliation":[{"name":"the Department of Medicine, divisions of Cardiovascular Diseases (J.S.Y., G.S.R., S.I.), Neurology (J.S.Y., P.K.), Radiology (J.V.), Vascular Surgery (W.D.J.), and Neurosurgery (W.S.F.), University of Alabama at Birmingham."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gary S.","family":"Roubin","sequence":"additional","affiliation":[{"name":"the Department of Medicine, divisions of Cardiovascular Diseases (J.S.Y., G.S.R., S.I.), Neurology (J.S.Y., P.K.), Radiology (J.V.), Vascular Surgery (W.D.J.), and Neurosurgery (W.S.F.), University of Alabama at Birmingham."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sriram","family":"Iyer","sequence":"additional","affiliation":[{"name":"the Department of Medicine, divisions of Cardiovascular Diseases (J.S.Y., G.S.R., S.I.), Neurology (J.S.Y., P.K.), Radiology (J.V.), Vascular Surgery (W.D.J.), and Neurosurgery (W.S.F.), University of Alabama at Birmingham."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiri","family":"Vitek","sequence":"additional","affiliation":[{"name":"the Department of Medicine, divisions of Cardiovascular Diseases (J.S.Y., G.S.R., S.I.), Neurology (J.S.Y., P.K.), Radiology (J.V.), Vascular Surgery (W.D.J.), and Neurosurgery (W.S.F.), University of Alabama at Birmingham."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter","family":"King","sequence":"additional","affiliation":[{"name":"the Department of Medicine, divisions of Cardiovascular Diseases (J.S.Y., G.S.R., S.I.), Neurology (J.S.Y., P.K.), Radiology (J.V.), Vascular Surgery (W.D.J.), and Neurosurgery (W.S.F.), University of Alabama at Birmingham."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"William D.","family":"Jordan","sequence":"additional","affiliation":[{"name":"the Department of Medicine, divisions of Cardiovascular Diseases (J.S.Y., G.S.R., S.I.), Neurology (J.S.Y., P.K.), Radiology (J.V.), Vascular Surgery (W.D.J.), and Neurosurgery (W.S.F.), University of Alabama at Birmingham."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Winfield S.","family":"Fisher","sequence":"additional","affiliation":[{"name":"the Department of Medicine, divisions of Cardiovascular Diseases (J.S.Y., G.S.R., S.I.), Neurology (J.S.Y., P.K.), Radiology (J.V.), Vascular Surgery (W.D.J.), and Neurosurgery (W.S.F.), University of Alabama at Birmingham."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"e_1_3_2_1_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM199108153250701"},{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1001\/jama.1995.03520420037035"},{"key":"e_1_3_2_3_2","unstructured":"Sundt TM Jr Meyer FB Piepgras DG Fodee NC Ebersold NJ Marsh WR.
