Despite the limited knowledge of the natural history of patients with symptomatic vertebral disease, endovascular revascularization techniques are now utilized in clinical practice. We sought to determine the risk of endovascular treatment for ECVAS with a systematic review of the literature.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Methods\u2014<\/jats:title>\n            <jats:p>A search strategy was used using the terms \u201cstenting,\u201d \u201cvertebral,\u201d \u201costium,\u201d \u201corigin,\u201d and \u201cextracranial\u201d through Medline.

The majority of patients (56%) were noted to have contralateral vertebral artery stenosis or occlusion and 92% were symptomatic at the time of treatment. A total of 11 patients (1.1%) experienced a stroke and 8 (0.8%) experienced a transient ischemic attack within 30 days of the procedure. Drug-eluting stents were associated with lower restenosis rates (11%) compared to bare metal stents (30%) at a mean of 24 months of follow-up.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusions\u2014<\/jats:title>\n            <jats:p>Stenting and angioplasty of ECVAS appear to have a low rate of periprocedural stroke or transient ischemic attack and restenosis rates that may not be as high as suspected. Given the frequency of ECVAS as an etiology for ischemic stroke, future studies aimed at determining efficacy of this treatment modality relative to medical therapy would be of benefit to clinicians caring for these patients.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1161\/strokeaha.110.611459","type":"journal-article","created":{"date-parts":[[2011,6,25]],"date-time":"2011-06-25T14:56:02Z","timestamp":1309013762000},"page":"2212-2216","update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":141,"title":["A Systematic Review of Stenting and Angioplasty of Symptomatic Extracranial Vertebral Artery Stenosis"],"prefix":"10.1161","volume":"42","author":[{"given":"Aaron N.","family":"Stayman","sequence":"first","affiliation":[{"name":"From the Department of Neurology (A.N.S.), Vanderbilt University School of Medicine, Nashville, TN; Departments of Neurology (R.G.N., R.G.), Neurosurgery and Radiology, Emory University School of Medicine, Marcus Stroke and Neuroscience Center, Grady Memorial Hospital, Atlanta, GA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Raul G.","family":"Nogueira","sequence":"additional","affiliation":[{"name":"From the Department of Neurology (A.N.S.), Vanderbilt University School of Medicine, Nashville, TN; Departments of Neurology (R.G.N., R.G.), Neurosurgery and Radiology, Emory University School of Medicine, Marcus Stroke and Neuroscience Center, Grady Memorial Hospital, Atlanta, GA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rishi","family":"Gupta","sequence":"additional","affiliation":[{"name":"From the Department of Neurology (A.N.S.), Vanderbilt University School of Medicine, Nashville, TN; Departments of Neurology (R.G.N., R.G.), Neurosurgery and Radiology, Emory University School of Medicine, Marcus Stroke and Neuroscience Center, Grady Memorial Hospital, Atlanta, GA."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1001\/jama.1968.03140110053011"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.STR.19.9.1083"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1159\/000016068"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1159\/000016042"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1001\/archneur.55.4.470"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/0741-5214(85)90025-4"},{"key":"e_1_3_2_8_2","first-page":"101","article-title":"Surgical repair of vertebral artery stenoses","volume":"2","author":"Thevenet A","year":"1984","unstructured":"Thevenet A, Ruotolo C.
