Seventy patients had a preoperative computerized tomography angiography scan prior to lower extremity intervention and 77% (54) had Trans-Atlantic Inter-Society Consensus D lesions that were crossed. Mean age was 62.8 years and 68.6% were male. Mean chronic total occlusion length was 182.7 mm (170.8 mm crossed vs. 222.6 mm uncrossed, p\u2009=\u20090.03). Calcium distribution differed significantly ( p&lt;.01): circumferential (14.8 vs. 12.5%); eccentric (85 vs. 62.5%); and complete calcium occlusion (0 vs. 25%) for lesions that were crossed and uncrossed, respectively. Significant differences ( p&lt;.0001) were found when calcium occlusion was less than 50% (87 vs. 31%), 51\u201375% (9.3 vs. 31.2%), and 76\u2013100% (3.7 vs. 37.5%). Total calcium length in crossed lesion was 51.6 mm, and 92.8 mm in uncrossed lesions ( p\u2009=\u20090.10). No significant differences were noted for patient gender, occlusion location (proximal, middle, and distal superficial femoral artery), and kidney function.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The Ocelot catheter is an effective method to cross long Trans-Atlantic Inter-Society Consensus D lesions. Superficial femoral artery lesions longer than 17 cm and focal plaque morphology, specifically a total cross-sectional area of calcium and a calcium surface area greater than 50% were most predictive of failure to cross Trans-Atlantic Inter-Society Consensus D superficial femoral artery lesions. Computerized tomography angiography is an effective tool to predict success for crossing chronic total occlusions using optical coherence tomography technology and a critical consideration for patient selection.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/1708538117742828","type":"journal-article","created":{"date-parts":[[2017,12,10]],"date-time":"2017-12-10T00:11:04Z","timestamp":1512864664000},"page":"362-367","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":4,"title":["Preoperative assessment of computerized tomography angiography to predict success for crossing long Trans-Atlantic Inter-Society Consensus D lesions using the optical coherence tomography catheter"],"prefix":"10.1177","volume":"26","author":[{"given":"Ryan J","family":"Kim","sequence":"first","affiliation":[{"name":"Division of Vascular Surgery, University of Missouri, School of Medicine, Columbia, MO, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jamie B","family":"Smith","sequence":"additional","affiliation":[{"name":"Department of Family and Community Medicine, University of Missouri, School of Medicine, Columbia, MO, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Todd R","family":"Vogel","sequence":"additional","affiliation":[{"name":"Division of Vascular Surgery, University of Missouri, School of Medicine, Columbia, MO, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2017,12,9]]},"reference":[{"key":"bibr1-1708538117742828","doi-asserted-by":"publisher","DOI":"10.1583\/13-4380MR.1"},{"key":"bibr2-1708538117742828","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2006.12.037"},{"key":"bibr3-1708538117742828","doi-asserted-by":"publisher","DOI":"10.4244\/EIJV9I7A139"},{"key":"bibr4-1708538117742828","doi-asserted-by":"publisher","DOI":"10.1016\/j.amjcard.2004.07.117"},{"key":"bibr5-1708538117742828","doi-asserted-by":"publisher","DOI":"10.1007\/BF02578675"},{"key":"bibr6-1708538117742828","doi-asserted-by":"publisher","DOI":"10.1007\/s00270-008-9331-7"},{"key":"bibr7-1708538117742828","doi-asserted-by":"crossref","first-page":"E2083","DOI":"10.1016\/S0735-1097(12)62084-1","volume":"59","author":"Krishnan P","year":"2012","journal-title":"J Am Coll Cardiol"},{"key":"bibr8-1708538117742828","doi-asserted-by":"publisher","DOI":"10.1002\/ccd.25187"},{"key":"bibr9-1708538117742828","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCULATIONAHA.112.117143"},{"key":"bibr10-1708538117742828","doi-asserted-by":"publisher","DOI":"10.1097\/00019501-200608000-00005"},{"key":"bibr11-1708538117742828","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2011.09.079"},{"key":"bibr12-1708538117742828","doi-asserted-by":"publisher","DOI":"10.1016\/j.carrev.2013.09.007"},{"key":"bibr13-1708538117742828","doi-asserted-by":"publisher","DOI":"10.1007\/s00270-011-0261-4"}],"container-title":["Vascular"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1708538117742828","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/1708538117742828","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1708538117742828","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,2]],"date-time":"2026-05-02T07:31:02Z","timestamp":1777707062000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/1708538117742828"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017,12,9]]},"references-count":13,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2018,8]]}},"alternative-id":["10.1177\/1708538117742828"],"URL":"https:\/\/doi.org\/10.1177\/1708538117742828","relation":{},"ISSN":["1708-5381","1708-539X"],"issn-type":[{"value":"1708-5381","type":"print"},{"value":"1708-539X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2017,12,9]]}}}
