The mean age was 72.3\u00b18.6 and 46% were male. Baseline National Institutes of Health Stroke Scale score was 19.5\u00b18.7, two patients (14%) received intravenous tissue plasminogen activator, and mean time from last known normal to intra-arterial therapy was 17.0\u00b120.1\u2005h. Five patients had anterior circulation occlusive disease and 10 had vertebrobasilar occlusions. TRA was effective in allowing clot engagement in 13 of 15 cases: one patient had a hypoplastic radial artery that precluded sheath advancement and one had chronic innominate artery occlusion that could not be crossed. Mean time to switch from TFA to TRA was 1.9\u00b11.3\u2005h and the mean time from radial puncture to reperfusion was 2.2\u00b11.0\u2005h. Modified Thrombolysis In Cerebral Infarction 2b\u20133 reperfusion via TRA was achieved in 9 of 15 patients (60%). No radial puncture site complications were noted. At 90\u2005days, two patients (13%) had a good clinical outcome and seven (50%) had died.<\/jats:p><\/jats:sec>Conclusions<\/jats:title>Failure of TFA in the endovascular treatment of AIS is uncommon but leads to unacceptable delays in reperfusion and poor outcomes. Standardization of benchmarks for access switch could serve as a guide for neurointerventionalists. TRA is a valid approach for the endovascular treatment of AIS.<\/jats:p><\/jats:sec>","DOI":"10.1136\/neurintsurg-2014-011519","type":"journal-article","created":{"date-parts":[[2015,1,6]],"date-time":"2015-01-06T02:11:00Z","timestamp":1420510260000},"page":"247-250","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":89,"title":["Transradial access in acute ischemic stroke intervention"],"prefix":"10.1136","volume":"8","author":[{"given":"Diogo C","family":"Haussen","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Raul G","family":"Nogueira","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Keith G","family":"DeSousa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ryan N","family":"Pafford","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nazli","family":"Janjua","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kevin N","family":"Ramdas","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eric C","family":"Peterson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohamed Samy","family":"Elhammady","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dileep R","family":"Yavagal","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2015,1,5]]},"reference":[{"key":"2024052302141997000_8.3.247.1","doi-asserted-by":"publisher","DOI":"10.1161\/01.STR.0000258112.14918.24"},{"key":"2024052302141997000_8.3.247.2","doi-asserted-by":"publisher","DOI":"10.1016\/S1474-4422(14)70066-3"},{"key":"2024052302141997000_8.3.247.3","doi-asserted-by":"publisher","DOI":"10.1177\/1538574411405547"},{"key":"2024052302141997000_8.3.247.4","doi-asserted-by":"publisher","DOI":"10.1136\/neurintsurg-2013-010971"},{"key":"2024052302141997000_8.3.247.5","doi-asserted-by":"publisher","DOI":"10.1002\/ccd.20738"},{"key":"2024052302141997000_8.3.247.6","doi-asserted-by":"publisher","DOI":"10.1161\/STROKEAHA.113.001972"},{"key":"2024052302141997000_8.3.247.7","doi-asserted-by":"publisher","DOI":"10.1136\/neurintsurg-2012-010438"},{"key":"2024052302141997000_8.3.247.8","doi-asserted-by":"crossref","first-page":"3","DOI":"10.1002\/ccd.1810160103","article-title":"Percutaneous radial artery approach for coronary angiography","volume":"16","author":"Campeau","year":"1989","journal-title":"Catheter Cardiovasc Interv"},{"key":"2024052302141997000_8.3.247.9","doi-asserted-by":"publisher","DOI":"10.3348\/kjr.2006.7.1.7"},{"key":"2024052302141997000_8.3.247.10","doi-asserted-by":"crossref","first-page":"605","DOI":"10.1080\/01616412.2000.11740727","article-title":"Transradial approach for selective cerebral angiography: technical note","volume":"22","author":"Matsumoto","year":"2000","journal-title":"Neurol Res"},{"key":"2024052302141997000_8.3.247.11","first-page":"543","article-title":"[Angioplasty with stent positioning at the level of the carotid bifurcation and dilatation with the kissing balloon technique between the origin of the internal and external carotid arteries.
