Its 19Fr low-profile delivery system may be effective for patients with low-calibre or hostile access vessels (AV), reducing trauma risk, improving limb perfusion during percutaneous procedures, and broadening FEVAR indications. This study evaluates short- and mid-term outcomes of the device and its viability in patients with hostile AV. Materials and methods: Only patients with hostile AV treated with the Fenestrated TREO\n                    <jats:sup>\u00ae<\/jats:sup>\n                    between 2022 and 2025 at a tertiary-care university centre were included. The primary endpoint was technical success. Secondary endpoints included AV-related intraoperative procedures, short- and mid-term morbidity, mortality, reintervention rate, AV-related complications and reinterventions, and stability of target vessels (TV). A sub-analysis compared patients with AV calibre &gt;6.3 mm (group A) and &lt;6.3 mm (group B). Results: Twenty-eight patients were included: 18 in group A and 10 in group B. Technical success was 100%, with target vessel cannulation achieved in 99.1% (one failure). Additional intraoperative AV preparation\/adjunctive procedures were required in eight patients (28.6%; 1 vs. 7, p &lt; .001). No perioperative or late deaths occurred. AV reinterventions were required in four patients (14.3%; 2 vs. 2, p = .561). Major complications occurred in four patients (14.3%), and three of 4 AV reinterventions were observed in this subgroup. One major reintervention was necessary. Early TV instability occurred in two patients (7.1%; 1 vs. 1, p = .712). During a median follow-up of 13 months, no late deaths or reinterventions were observed. Conclusions: In patients with hostile AV, the Fenestrated TREO\n                    <jats:sup>\u00ae<\/jats:sup>\n                    graft showed high technical success rates and favourable short-term outcomes, with acceptable complication rates and excellent TV stability, aligning with results of other well-established endografts. Its low-profile design may be advantageous in complex AV anatomies. Additional intraoperative AV-related procedures mainly occurred in cases of very narrow AV (group B), while postoperative AV-related complications and reinterventions were similar between groups.\n                  <\/jats:p>","DOI":"10.1024\/0301-1526\/a001298","type":"journal-article","created":{"date-parts":[[2026,8,18]],"date-time":"2026-08-18T04:56:11Z","timestamp":1787028971000},"source":"Crossref","is-referenced-by-count":0,"title":["Fenestrated TREO\n                    <sup>\u00ae<\/sup>\n                    low-profile endograft in hostile access vessels"],"prefix":"10.1024","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-5600-2333","authenticated-orcid":true,"given":"Florian","family":"Elger","sequence":"first","affiliation":[{"name":"Department of Cardiac, Thoracic and Vascular Surgery, University Medical Center G\u00f6ttingen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-2434-7299","authenticated-orcid":true,"given":"Marcello","family":"Silvano","sequence":"additional","affiliation":[{"name":"Department of Cardiac, Thoracic and Vascular Surgery, University Medical Center G\u00f6ttingen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eberhard","family":"Grambow","sequence":"additional","affiliation":[{"name":"Department of Cardiac, Thoracic and Vascular Surgery, University Medical Center G\u00f6ttingen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Teodora","family":"Ormandzhieva","sequence":"additional","affiliation":[{"name":"Department of Cardiac, Thoracic and Vascular Surgery, University Medical Center G\u00f6ttingen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rukiye","family":"Secer","sequence":"additional","affiliation":[{"name":"Department of Cardiac, Thoracic and Vascular Surgery, University Medical Center G\u00f6ttingen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"101","published-online":{"date-parts":[[2026,8,18]]},"reference":[{"key":"c1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2014.09.068"},{"key":"c2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2018.08.159"},{"key":"c3","doi-asserted-by":"publisher","DOI":"10.1097\/SLA.0000000000004982"},{"key":"c4","doi-asserted-by":"publisher","DOI":"10.1177\/1526602821991125"},{"key":"c5","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2017.04.063"},{"key":"c6","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2021.07.237"},{"key":"c7","doi-asserted-by":"publisher","DOI":"10.1177\/15266028241227392"},{"key":"c8","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2022.05.028"},{"key":"c9","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2006.12.037"},{"key":"c10","doi-asserted-by":"publisher","DOI":"10.1007\/s00270-020-02414-8"},{"key":"c11","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2020.06.011"},{"key":"c12","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2016.09.038"},{"key":"c13","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2023.05.003"},{"key":"c14","doi-asserted-by":"publisher","DOI":"10.1055\/s-0043-101387"},{"key":"c15","doi-asserted-by":"publisher","DOI":"10.1177\/1708538120965310"},{"key":"c16","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2018.12.025"},{"issue":"2","key":"c17","first-page":"204","volume":"58","author":"De Almeida Sandri G","year":"2017","journal-title":"J Cardiovasc Surg (Torino)."},{"key":"c18","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejvs.2024.10.032"},{"key":"c19","doi-asserted-by":"publisher","DOI":"10.1016\/j.avsg.2022.10.001"},{"key":"c20","doi-asserted-by":"publisher","DOI":"10.1177\/15266028211007468"},{"key":"c21","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvscit.2020.09.002"},{"key":"c22","doi-asserted-by":"publisher","DOI":"10.1136\/bcr-2020-240876"},{"key":"c23","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcin.2024.08.033"},{"key":"c24","doi-asserted-by":"publisher","DOI":"10.1024\/0301-1526\/a001148"}],"container-title":["Vasa"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/econtent.hogrefe.com\/doi\/pdf\/10.1024\/0301-1526\/a001298","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,8,18]],"date-time":"2026-08-18T04:56:12Z","timestamp":1787028972000},"score":1,"resource":{"primary":{"URL":"https:\/\/econtent.hogrefe.com\/doi\/10.1024\/0301-1526\/a001298"}},"subtitle":["Feasibility and outcomes from a single-centre cohort"],"short-title":[],"issued":{"date-parts":[[2026,8,18]]},"references-count":24,"alternative-id":["10.1024\/0301-1526\/a001298"],"URL":"https:\/\/doi.org\/10.1024\/0301-1526\/a001298","relation":{},"ISSN":["0301-1526","1664-2872"],"issn-type":[{"value":"0301-1526","type":"print"},{"value":"1664-2872","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,8,18]]},"article-number":"0301-1526\/a001298"}}
