Up to 15 sites in Europe were required to enroll a minimum of 220 patients. Patients\u2019 medical records were reviewed by the investigator, and specific data were collected ambispectively for up to 5 years of follow-up from the index procedure. The primary end point is target vessel patency (patient level) through 12 months. The registry was designed to statistically test target vessel patency at 12 months in both FEVAR and BEVAR populations. The hypothesis will be tested separately in the 2 cohorts (fenestrated or branched endovascular repair), using patients with core laboratory imaging results available annually through 5 years. The binomial exact test will be used with a 1-sided 2.5% level of significance to test the null hypothesis.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n In total, 259 patients were retrospectively enrolled for a prospective follow-up of 5 years: 136 patients (n=99, 72.8% male; mean age 73, SD 8.9 y) in the BEVAR cohort, 92 patients (n=80, 87.0% male, mean age 72.7, SD 8.1 y) in the FEVAR cohort, and 31 patients (n=17, 54.8% male, mean age 70.9, SD 9.4 y) in the mixed fenestrated or branched endovascular repair cohort. Overall, 662 target vessels were stented with the investigational covered stents: 163 (24.6%) celiac trunk, 192 (29.0%) superior mesenteric artery, and 307 (46.4%) renal arteries. The VBX stent grafts were paired with branches in 451 (68.1%) cases or fenestrations in 211 (31.9%) cases among all Cook Medical stent graft cases. The 1-year results will be published in the fourth quarter of\n \n 2025, and the 5-year follow-up results will be analyzed by mid-year 2028.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n This study will investigate the VBX stent graft performance in combination with fenestrated and branched aortic grafts to corroborate its use in complex aortic endovascular procedures and support the modification of current device instructions for use.<\/jats:p>\n <\/jats:sec>","DOI":"10.2196\/78970","type":"journal-article","created":{"date-parts":[[2025,12,29]],"date-time":"2025-12-29T18:45:08Z","timestamp":1767033908000},"page":"e78970-e78970","source":"Crossref","is-referenced-by-count":3,"title":["GORE VIABAHN VBX Balloon-Expandable Endoprostheses as a Bridging Stent With Branched and Fenestrated Endografts in the Endovascular Treatment of Aortic Aneurysms: Protocol for a Retrospective Multicenter Registry (EMBRACE Study)"],"prefix":"10.2196","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-3053-8384","authenticated-orcid":false,"given":"Pietro","family":"Dioni","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3273-8726","authenticated-orcid":false,"given":"Anders","family":"Wanhainen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6181-6391","authenticated-orcid":false,"given":"Jacob","family":"Budtz-Lilly","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6907-6148","authenticated-orcid":false,"given":"Nuno","family":"Dias","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-5628-9475","authenticated-orcid":false,"given":"Tab","family":"Bonny","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6871-2176","authenticated-orcid":false,"given":"Luca","family":"Bertoglio","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"EMBRACE study investigator","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1010","published-online":{"date-parts":[[2026,2,27]]},"reference":[{"issue":"1","key":"R1","doi-asserted-by":"publisher","first-page":"4S","DOI":"10.1016\/j.jvs.2020.06.011","article-title":"Reporting standards for endovascular aortic repair of aneurysms involving the renal-mesenteric arteries","volume":"73","author":"Oderich","journal-title":"J Vasc Surg"},{"issue":"4","key":"R2","doi-asserted-by":"publisher","first-page":"565","DOI":"10.1016\/j.ejvs.2019.10.003","article-title":"Elective multistaged endovascular repair of thoraco-abdominal aneurysms with fenestrated and branched endografts to mitigate spinal cord ischaemia","volume":"59","author":"Bertoglio","journal-title":"Eur J Vasc Endovasc Surg"},{"issue":"4","key":"R3","doi-asserted-by":"publisher","first-page":"e893","DOI":"10.1097\/SLA.0000000000005859","article-title":"Mid-term renal and mesenteric artery outcomes during fenestrated and branched endovascular aortic repair for complex abdominal and thoracoabdominal aortic aneurysms in the United States aortic research consortium","volume":"278","author":"Tenorio","journal-title":"Ann Surg"},{"issue":"36","key":"R4","doi-asserted-by":"publisher","first-page":"3538","DOI":"10.1093\/eurheartj\/ehae179","article-title":"2024 ESC Guidelines for the management of peripheral arterial and aortic diseases","volume":"45","author":"Mazzolai","journal-title":"Eur Heart J"},{"issue":"4","key":"R5","doi-asserted-by":"publisher","first-page":"854","DOI":"10.1016\/j.jvs.2023.05.053","article-title":"Multicenter trans-Atlantic experience with fenestrated-branched endovascular aortic repair of chronic post-dissection thoracoabdominal aortic aneurysms","volume":"78","author":"Abdelhalim","journal-title":"J Vasc Surg"},{"issue":"2","key":"R6","doi-asserted-by":"publisher","first-page":"230","DOI":"10.1177\/1526602817752449","article-title":"Preliminary outcomes of the LifeStream balloon-expandable covered stent in fenestrated and branched thoracoabdominal endovascular repairs","volume":"25","author":"Bertoglio","journal-title":"J Endovasc Ther"},{"key":"R7","unstructured":"International ethical guidelines for health-related research involving humans.
