Methods: Between June 2011 and December 2013, 40 TEVAR procedures were performed in our facility, including 10 cases in which in situ fenestration was planned. Two thoracic stent-graft models were deployed: the Valiant (n=5) and the Zenith TX2 (n=5). A 0.035-inch PowerWire radiofrequency guidewire delivered from a brachial approach was used to fenestrate the grafts covering a left subclavian artery (LSA) in 9 cases and a left common carotid artery in one. The fenestrations were serially dilated to 6 mm, and self-expanding Advanta V12 covered stents were positioned in the target arteries. Results: Technical success was achieved in 6 of the 10 planned cases. Of the remaining 4 cases, stent-grafts were deployed in zone 3 in 2 cases (one received a chimney to the LSA). Another stent-graft was deployed in zone 2 without endoleak after fenestration was abandoned (the LSA had good filling via the vertebral artery). In the last case, the fenestration was unsuccessful in double-layered (proximal extension overlap) stent-grafts; a carotid-axillary bypass was required. There were no fenestration-related complications, but overall surgical complications included a case of paraparesis that resolved following spinal drainage and a death from a preexisting aortoesophageal fistula. There were no postoperative strokes. All fenestrations remained patent, and there were no endoleaks at a mean 12-month follow-up (range 1\u201333). Conclusion: Radiofrequency puncture is a viable alternative to needle or laser punctures for in situ fenestration during TEVAR. Early clinical results suggest technical feasibility and acceptable early outcomes.<\/jats:p>","DOI":"10.1177\/1526602814565776","type":"journal-article","created":{"date-parts":[[2015,3,20]],"date-time":"2015-03-20T21:31:11Z","timestamp":1426887071000},"page":"116-121","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":86,"title":["Radiofrequency In Situ Fenestration for Aortic Arch Vessels During Thoracic Endovascular Repair"],"prefix":"10.1177","volume":"22","author":[{"given":"Leonard W.","family":"Tse","sequence":"first","affiliation":[{"name":"Toronto General Hospital, University Heath Network, University of Toronto, Ontario, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas F.","family":"Lindsay","sequence":"additional","affiliation":[{"name":"Toronto General Hospital, University Heath Network, University of Toronto, Ontario, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Graham","family":"Roche-Nagle","sequence":"additional","affiliation":[{"name":"Toronto General Hospital, University Heath Network, University of Toronto, Ontario, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"George D.","family":"Oreopoulos","sequence":"additional","affiliation":[{"name":"Toronto General Hospital, University Heath Network, University of Toronto, Ontario, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maral","family":"Ouzounian","sequence":"additional","affiliation":[{"name":"Toronto General Hospital, University Heath Network, University of Toronto, Ontario, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kong Teng","family":"Tan","sequence":"additional","affiliation":[{"name":"Toronto General Hospital, University Heath Network, University of Toronto, Ontario, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2015,2,1]]},"reference":[{"key":"bibr1-1526602814565776","doi-asserted-by":"publisher","DOI":"10.1583\/03-1180.1"},{"key":"bibr2-1526602814565776","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2009.07.088"},{"key":"bibr3-1526602814565776","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2009.02.007"},{"key":"bibr4-1526602814565776","doi-asserted-by":"publisher","DOI":"10.1583\/11-3574MR.1"},{"key":"bibr5-1526602814565776","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvir.2011.04.002"},{"key":"bibr6-1526602814565776","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2013.04.045"},{"key":"bibr7-1526602814565776","doi-asserted-by":"publisher","DOI":"10.1583\/09-2746.1"},{"key":"bibr8-1526602814565776","doi-asserted-by":"publisher","DOI":"10.1583\/09-2903.1"},{"key":"bibr9-1526602814565776","doi-asserted-by":"publisher","DOI":"10.1583\/12-4175.1"},{"key":"bibr10-1526602814565776","doi-asserted-by":"publisher","DOI":"10.1510\/icvts.2008.175000"},{"key":"bibr11-1526602814565776","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejvs.2014.02.008"},{"key":"bibr12-1526602814565776","doi-asserted-by":"publisher","DOI":"10.1177\/152660280701400207"},{"key":"bibr13-1526602814565776","doi-asserted-by":"publisher","DOI":"10.1016\/j.avsg.2009.06.022"},{"key":"bibr14-1526602814565776","doi-asserted-by":"publisher","DOI":"10.1016\/j.jtcvs.2013.12.020"},{"key":"bibr15-1526602814565776","doi-asserted-by":"publisher","DOI":"10.1007\/s00270-008-9459-5"}],"container-title":["Journal of Endovascular Therapy"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1526602814565776","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/1526602814565776","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1526602814565776","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T21:27:56Z","timestamp":1777498076000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/1526602814565776"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015,2]]},"references-count":15,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2015,2]]}},"alternative-id":["10.1177\/1526602814565776"],"URL":"https:\/\/doi.org\/10.1177\/1526602814565776","relation":{},"ISSN":["1526-6028","1545-1550"],"issn-type":[{"value":"1526-6028","type":"print"},{"value":"1545-1550","type":"electronic"}],"subject":[],"published":{"date-parts":[[2015,2]]}}}
