Thirty-four patients (15 men, 19 women; median age, 67.5 years) with symptomatic MCA stenosis underwent balloon-expandable stent insertion between June 2008 and December 2010. Patient records were reviewed for angiographic findings and clinical outcomes during long-term follow-up.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Of these patients, 22 presented with acute ischemic stroke with underlying MCA atherosclerosis and had good clinical outcomes (modified Rankin Scale score (mRS): 0\u20132) after reperfusion therapy. Indications for stenting for the remaining 12 patients were recurrent transient ischemic attacks (TIAs) refractory to medical therapy and MCA stenosis greater than 70%. During the poststenting follow-up period, which ranged from 61 to 108 months (median, 67.5 months), a TIA occurred in five patients. Of these five patients, one experienced a complete reocclusion of the MCA stent, and three had symptomatic restenosis. The remaining 29 patients did not experience any further ischemic events or restenosis during the follow-up period.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>In our study, treatment with balloon-expandable stents in patients with symptomatic MCA stenosis resulted in low recurrence rates for both ischemic events and restenosis during long-term follow-up.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/1591019918786515","type":"journal-article","created":{"date-parts":[[2018,7,11]],"date-time":"2018-07-11T01:06:06Z","timestamp":1531271166000},"page":"666-673","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":15,"title":["Balloon-expandable stents for treatment of symptomatic middle cerebral artery stenosis: Clinical outcomes during long-term follow-up"],"prefix":"10.1177","volume":"24","author":[{"given":"Sung Hyun","family":"Baik","sequence":"first","affiliation":[{"name":"Department of Radiology, Severance Hospital, Seoul, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hyo Sung","family":"Kwak","sequence":"additional","affiliation":[{"name":"Radiology and Research Institute of Clinical Medicine of Chonbuk National University-Biomedical Research Institute of Chonbuk National University Hospital, Jeonju, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gyung Ho","family":"Chung","sequence":"additional","affiliation":[{"name":"Radiology and Research Institute of Clinical Medicine of Chonbuk National University-Biomedical Research Institute of Chonbuk National University Hospital, Jeonju, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seung Bae","family":"Hwang","sequence":"additional","affiliation":[{"name":"Radiology and Research Institute of Clinical Medicine of Chonbuk National University-Biomedical Research Institute of Chonbuk National University Hospital, Jeonju, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2018,7,10]]},"reference":[{"key":"bibr1-1591019918786515","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.40.10.1540"},{"key":"bibr2-1591019918786515","doi-asserted-by":"publisher","DOI":"10.1161\/01.STR.27.11.1974"},{"key":"bibr3-1591019918786515","doi-asserted-by":"publisher","DOI":"10.1159\/000068744"},{"key":"bibr4-1591019918786515","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.45.8.1488"},{"key":"bibr5-1591019918786515","doi-asserted-by":"publisher","DOI":"10.1161\/01.STR.26.1.14"},{"key":"bibr6-1591019918786515","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa1105335"},{"key":"bibr7-1591019918786515","doi-asserted-by":"publisher","DOI":"10.1001\/jama.2015.1693"},{"key":"bibr8-1591019918786515","doi-asserted-by":"publisher","DOI":"10.3174\/ajnr.A2208"},{"key":"bibr9-1591019918786515","doi-asserted-by":"publisher","DOI":"10.1161\/STROKEAHA.111.622282"},{"key":"bibr10-1591019918786515","doi-asserted-by":"publisher","DOI":"10.1177\/159101991201800111"},{"key":"bibr11-1591019918786515","doi-asserted-by":"publisher","DOI":"10.1007\/s00234-010-0826-y"},{"key":"bibr12-1591019918786515","doi-asserted-by":"publisher","DOI":"10.1161\/STROKEAHA.111.613877"},{"key":"bibr13-1591019918786515","doi-asserted-by":"publisher","DOI":"10.1007\/s00270-010-9885-z"},{"key":"bibr14-1591019918786515","doi-asserted-by":"publisher","DOI":"10.1159\/000144082"},{"key":"bibr15-1591019918786515","doi-asserted-by":"publisher","DOI":"10.1111\/j.1468-1331.2008.02297.x"},{"key":"bibr16-1591019918786515","doi-asserted-by":"publisher","DOI":"10.1161\/STROKEAHA.108.532713"},{"key":"bibr17-1591019918786515","doi-asserted-by":"publisher","DOI":"10.1227\/01.NEU.0000255521.42579.31"},{"key":"bibr18-1591019918786515","doi-asserted-by":"crossref","unstructured":"SSYLVIA Study Investigators: Stenting of Symptomatic Atherosclerotic Lesions in the Vertebral or Intracranial Arteries (SSYLVIA): Study results.\n                      Stroke\n                      2004;
