Clinical performance and complication rates were evaluated, with particular consideration of vessel tortuosity. A total of 62 Benchmarks were used, 47 in the anterior circulation, 10 in the posterior circulation, 4 in the external carotid, and 1 in the venous sinus. The five cases with access to the external carotid and venous sinus were excluded.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>The Benchmark was able to cross at least one 90\u00b0 turn in 49 (86%) of the 57 patients. Reversal of the catheter was seen in 15% of 47 anterior circulation cases (4 at one 90\u00b0 turn; 3 at two 90\u00b0 turns). We report no complications of dissection or thromboembolic events. All guide catheter positions were safely achieved over a 0.035 Terumo stiff glidewire without need for an inner smaller lumen guide catheter for navigation.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>Benchmark is a new guide catheter, with an ideal combination of both hyperflexible, atraumatic distal tip and optimized proximal shaft support to provide stable 6F primary access for a successful neurointerventional procedure. Benchmark can be easily, safely, and consistently positioned in a desired location within intracranial arteries providing a stable position for intervention and adequate angiography.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1136\/neurintsurg-2015-011788","type":"journal-article","created":{"date-parts":[[2015,6,12]],"date-time":"2015-06-12T22:05:08Z","timestamp":1434146708000},"page":"718-721","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":17,"title":["Distal access using hyperflexible atraumatic distal tip with optimized proximal stability of the Benchmark intracranial guide catheter for the treatment of cerebral vascular diseases: a technical note"],"prefix":"10.1136","volume":"8","author":[{"given":"Arun","family":"Chandran","sequence":"first","affiliation":[{"name":"Neuroradiology Department, The Walton Centre NHS Foundation Trust, Liverpool, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mani","family":"Puthuran","sequence":"additional","affiliation":[{"name":"Neuroradiology Department, The Walton Centre NHS Foundation Trust, Liverpool, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul R","family":"Eldridge","sequence":"additional","affiliation":[{"name":"Neurosurgery Department, The Walton Centre NHS Foundation Trust, Liverpool, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hans C","family":"Nahser","sequence":"additional","affiliation":[{"name":"Neuroradiology Department, The Walton Centre NHS Foundation Trust, Liverpool, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2015,6,12]]},"reference":[{"key":"2025092911150650000_8.7.718.1","doi-asserted-by":"publisher","DOI":"10.1161\/01.STR.0000259824.10732.bb"},{"key":"2025092911150650000_8.7.718.2","doi-asserted-by":"publisher","DOI":"10.1227\/01.NEU.0000103672.96785.42"},{"key":"2025092911150650000_8.7.718.3","doi-asserted-by":"publisher","DOI":"10.1007\/s00234-006-0157-1"},{"key":"2025092911150650000_8.7.718.4","first-page":"1502","article-title":"Direct carotid puncture for the endovascular treatment of anterior circulation aneurysms","volume":"27","author":"Nii","year":"2006","journal-title":"AJNR Am J Neuroradiol"},{"key":"2025092911150650000_8.7.718.5","doi-asserted-by":"publisher","DOI":"10.1016\/j.surneu.2006.03.044"},{"key":"2025092911150650000_8.7.718.6","doi-asserted-by":"crossref","first-page":"737","DOI":"10.1016\/j.surneu.2009.03.016","article-title":"Distal intracranial catheterization of patients with tortuous vascular anatomy using a new hybrid guide catheter","volume":"72","author":"Simon","year":"2009","journal-title":"Surg Neurol"},{"key":"2025092911150650000_8.7.718.7","first-page":"1375","article-title":"Techniques for intracranial stent navigation in patients with tortuous vessels","volume":"26","author":"Lee","year":"2005","journal-title":"AJNR Am J Neuroradiol"},{"key":"2025092911150650000_8.7.718.8","doi-asserted-by":"publisher","DOI":"10.1007\/s00234-007-0313-2"},{"key":"2025092911150650000_8.7.718.9","doi-asserted-by":"publisher","DOI":"10.1227\/01.NEU.0000154820.28342.38"},{"key":"2025092911150650000_8.7.718.10","doi-asserted-by":"publisher","DOI":"10.1136\/neurintsurg-2011-010256"},{"key":"2025092911150650000_8.7.718.11","doi-asserted-by":"publisher","DOI":"10.1136\/neurintsurg-2011-010041"},{"key":"2025092911150650000_8.7.718.12","doi-asserted-by":"publisher","DOI":"10.1136\/neurintsurg-2013-010772"}],"container-title":["Journal of NeuroInterventional Surgery"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/neurintsurg-2015-011788","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,9,29]],"date-time":"2025-09-29T18:15:15Z","timestamp":1759169715000},"score":1,"resource":{"primary":{"URL":"https:\/\/jnis.bmj.com\/lookup\/doi\/10.1136\/neurintsurg-2015-011788"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015,6,12]]},"references-count":12,"journal-issue":{"issue":"7","published-online":{"date-parts":[[2016,6,14]]},"published-print":{"date-parts":[[2016,7]]}},"alternative-id":["10.1136\/neurintsurg-2015-011788"],"URL":"https:\/\/doi.org\/10.1136\/neurintsurg-2015-011788","relation":{},"ISSN":["1759-8478","1759-8486"],"issn-type":[{"value":"1759-8478","type":"print"},{"value":"1759-8486","type":"electronic"}],"subject":[],"published":{"date-parts":[[2015,6,12]]}}}
