We evaluated outcome in high-risk patients with symptomatic near occlusion.<\/jats:p>\n                  <jats:p>For 48 patients with near occlusion out of 166 symptomatic high-risk patients who underwent carotid stenting, we assessed the procedural success defined as residual stenosis &lt;30%, modified Rankin Scale (mRS) at one and six months following stenting, and the 13 cerebrovascular factors related to the outcome. Initial National Institutes of Health Stroke Scale (NIHSS) \u22654, 1\u20133 and 0 were 13, 14 and 21 patients each. We compared the outcome with patients who underwent CAS (n=118) due to symptomatic stenosis without near occlusion during the same period.<\/jats:p>\n                  <jats:p>Our procedural success rate was 98%. A good outcome (mRS \u22642) was achieved in 44 patients (92%) at six months. There were five events (10%) within six months, i.e. three minor strokes, one major stroke caused by hemorrhage, and one death excluding two deaths not related to stroke. Hyperperfusion (n=4) was the most common cause of events leading to two minor strokes and a major stroke. Although initial NIHSS (P = .012) was related to poor outcome (mRS &gt;2) compared to the CAS group, there was no statistical significance between two groups in the event rate of stroke, death or restenosis.<\/jats:p>\n                  <jats:p>The outcome of carotid stenting in high-risk patients with symptomatic near occlusion did not reveal any difference compared with CAS. Poor outcome was related to the initial NIHSS (\u22654). Hyperperfusion tended to be more commonly related to an event occurring after stenting.<\/jats:p>","DOI":"10.1177\/159101991001600314","type":"journal-article","created":{"date-parts":[[2017,1,10]],"date-time":"2017-01-10T14:59:55Z","timestamp":1484060395000},"page":"309-316","source":"Crossref","is-referenced-by-count":23,"title":["Outcome Evaluation of Carotid Stenting in High-Risk Patients with Symptomatic Carotid near Occlusion"],"prefix":"10.1177","volume":"16","author":[{"given":"B.S.","family":"Choi","sequence":"first","affiliation":[{"name":"Department of Radiology and Research Institute of Radiology, University of Ulsan, College of Medicine, Asan Medical Center;
