Therefore, carotid angiography on the affected side during revascularization therapy of acute ICA occlusion has a potential risk of causing distal embolization. In this study the authors propose the use of contralateral carotid angiography.<\/jats:p><\/jats:sec><jats:sec><jats:title>METHODS<\/jats:title><jats:p>Six patients with acute ICA occlusion underwent revascularization therapy using a stent retriever or Penumbra system. Revascularization therapy was performed with placement of a 9-Fr balloon-guiding catheter (BGC) in the affected ICA and a 4-Fr diagnostic catheter in the contralateral ICA. During the procedure, the 9-Fr BGC was kept inflated, and all control angiography was performed from the 4-Fr diagnostic catheter. After thrombectomy, contralateral carotid angiography combined with manual aspiration from the 9-Fr BGC was performed to assess the presence or absence of residual thrombi in the affected ICA. The 9-Fr BGC was deflated only after the complete absence of residual thrombi in the affected ICA was confirmed.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p>The time required for introducing the 4-Fr diagnostic catheter into the contralateral ICA was within a few minutes in all patients. Residual thrombi in the affected ICA were found in 3 of 6 patients. The residual thrombi in these 3 patients were completely removed; thus, distal embolization was prevented.<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSIONS<\/jats:title><jats:p>Contralateral carotid angiography is useful for avoiding distal embolization during revascularization therapy of acute ICA occlusion. Further studies involving a larger number of patients are warranted to verify the clinical efficacy of this contralateral carotid angiography.<\/jats:p><\/jats:sec>","DOI":"10.3171\/2017.3.jns162563","type":"journal-article","created":{"date-parts":[[2017,9,22]],"date-time":"2017-09-22T17:31:45Z","timestamp":1506101505000},"page":"465-470","source":"Crossref","is-referenced-by-count":4,"title":["Usefulness of contralateral carotid angiography in revascularization therapy of acute internal carotid artery occlusion"],"prefix":"10.3171","volume":"129","author":[{"given":"Kiyoshi","family":"Tsuji","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Kindai University Faculty of Medicine, Osaka; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nobuhiro","family":"Nakagawa","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Kindai University Faculty of Medicine, Osaka; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Norihito","family":"Fukawa","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Kindai University Faculty of Medicine, Osaka; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masaharu","family":"Miyauchi","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Kindai University Faculty of Medicine, Osaka; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kentaro","family":"Furukawa","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Kindai University Faculty of Medicine, Osaka; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kinya","family":"Nakanishi","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Nara Hospital, Kindai University Faculty of Medicine, Nara, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Naoki","family":"Nakano","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Kindai University Faculty of Medicine, Osaka; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kazuo","family":"Kataoka","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Nara Hospital, Kindai University Faculty of Medicine, Nara, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Amami","family":"Kato","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Kindai University Faculty of Medicine, Osaka; and"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1","series-title":"N Engl J Med","doi-asserted-by":"publisher","first-page":"11","DOI":"10.1056\/NEJMoa1411587","article-title":"A randomized trial of intraarterial treatment for acute ischemic stroke","volume":"372","author":"Berkhemer OA","year":"2015","unstructured":"Berkhemer OA, Fransen PS, Beumer D, van den Berg LA, Lingsma HF, Yoo AJ, : A randomized trial of intraarterial treatment for acute ischemic stroke.
