We describe a simple and effective technique to overcome the step-off between the intermediate catheter and an intracranial vessel stenosis during thrombectomy. The patient presented with acute embolic left middle cerebral artery occlusion and a favorable penumbral pattern. Clot access was made challenging by focal stenosis in the ipsilateral cavernous segment. The balloon-assisted tracking technique was effective in traversing the step-off to enable TICI 3 aspiration thrombectomy. This simple and effective technique should be kept in mind during stroke procedures where a proximal stenotic obstacle complicates access to the site of occlusion.<\/jats:p>","DOI":"10.1136\/neurintsurg-2018-014275.rep","type":"journal-article","created":{"date-parts":[[2018,12,22]],"date-time":"2018-12-22T22:19:26Z","timestamp":1545517166000},"page":"e1-e1","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":7,"title":["Balloon-assisted tracking technique to overcome intracranial stenosis during thrombectomy for stroke"],"prefix":"10.1136","volume":"11","author":[{"given":"Jan-Karl","family":"Burkhardt","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maksim","family":"Shapiro","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Omar","family":"Tanweer","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Miguel","family":"Litao","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Breehan","family":"Chancellor","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eytan","family":"Raz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Howard A","family":"Riina","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peter Kim","family":"Nelson","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2018,12,22]]},"reference":[{"key":"2024052304365398000_11.3.e1.1","doi-asserted-by":"publisher","DOI":"10.1177\/1591019917729364"},{"key":"2024052304365398000_11.3.e1.2","doi-asserted-by":"publisher","DOI":"10.3174\/ajnr.A4222"},{"key":"2024052304365398000_11.3.e1.3","doi-asserted-by":"crossref","first-page":"e211","DOI":"10.1016\/j.jstrokecerebrovasdis.2017.07.017","article-title":"Direct common carotid artery puncture for endovascular treatment of acute large vessel ischemic stroke in a patient with aortic coarctation","volume":"26","author":"Roche","year":"2017","journal-title":"J Stroke Cerebrovasc Dis"},{"key":"2024052304365398000_11.3.e1.4","doi-asserted-by":"publisher","DOI":"10.1136\/neurintsurg-2017-013584"},{"key":"2024052304365398000_11.3.e1.5","doi-asserted-by":"crossref","first-page":"211","DOI":"10.1002\/ccd.24959","article-title":"Balloon-assisted tracking: a must-know technique to overcome difficult anatomy during transradial approach","volume":"83","author":"Patel","year":"2014","journal-title":"Catheter Cardiovasc Interv"},{"key":"2024052304365398000_11.3.e1.6","doi-asserted-by":"crossref","first-page":"564","DOI":"10.1016\/j.carrev.2017.12.002","article-title":"Balloon-assisted tracking: a practical solution to avoid radial access failure due to difficult anatomical challenges","volume":"19","author":"Felekos","year":"2018","journal-title":"Cardiovasc Revasc Med"},{"key":"2024052304365398000_11.3.e1.7","first-page":"219","article-title":"Balloon-assisted tracking use reduces radial artery access failure in an experienced radial center and is feasible during primary PCI for STEMI","volume":"29","author":"Obaid","year":"2017","journal-title":"J Invasive Cardiol"}],"container-title":["Journal of NeuroInterventional Surgery"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/neurintsurg-2018-014275.rep","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,5,23]],"date-time":"2024-05-23T12:12:02Z","timestamp":1716466322000},"score":1,"resource":{"primary":{"URL":"https:\/\/jnis.bmj.com\/lookup\/doi\/10.1136\/neurintsurg-2018-014275.rep"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,12,22]]},"references-count":7,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2019,2,18]]},"published-print":{"date-parts":[[2019,3]]}},"alternative-id":["10.1136\/neurintsurg-2018-014275.rep"],"URL":"https:\/\/doi.org\/10.1136\/neurintsurg-2018-014275.rep","relation":{},"ISSN":["1759-8478","1759-8486"],"issn-type":[{"value":"1759-8478","type":"print"},{"value":"1759-8486","type":"electronic"}],"subject":[],"published":{"date-parts":[[2018,12,22]]}}}
