The EAs were deployed during primary EVAR (primary arm [PA]) or revisions for failing proximal fixation (revision arm [RA]). The primary endpoint was freedom from type 1a endoleak (T1aEL) and\/or stent-graft migration; secondary end points were proximal reintervention-free survival and overall survival.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The median follow-up among the 92 patients was 4.1 years (interquartile range=2.0-6.4). The PA consisted of 73 patients, of which 85% had hostile infrarenal neck morphology. In the RA, 19 patients received EAs, combined with an infrarenal extension cuff in 90% of cases. Treatment success, defined as absence of T1aEL on the first (&lt;60 days) post-operative imaging studies, was 97% in the PA and 74% in the RA, respectively. Five-year freedom from T1aEL and\/or stent-graft migration was 87.3% in the PA and 58.8% in the RA. Overall survival at 5 years was 65.1% and 51.4% in the PA and RA, respectively, and freedom from proximal reintervention was 89.3% in the PA and 79.7% in the RA.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>In this single-center retrospective series, EndoAnchors used during primary EVAR in hostile neck anatomy demonstrated high mid-term freedom from T1aEL and\/or stent-graft migration. The use of EAs to treat proximal failure of aortic endografts showed less benefit. In these complex cases, fenestrated EVAR or open repair may be more appropriate.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Clinical Impact<\/jats:title>\n                    <jats:p>This study demonstrates that the use of EndoAnchors during primary endovascular aortic aneurysm repair (EVAR) is associated with high mid-term freedom from type 1a endoleaks and stent-graft migration. These findings suggest that EndoAnchor placement may improve EVAR durability, particularly in patients with hostile neck anatomy, and reduce the need for secondary interventions in this high-risk group. In contrast, the more limited benefit observed in revision settings highlights the need to carefully consider alternative treatment strategies when treating proximal failure after EVAR.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/15266028261434173","type":"journal-article","created":{"date-parts":[[2026,4,14]],"date-time":"2026-04-14T07:27:17Z","timestamp":1776151637000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["EndoAnchors for Prevention and Treatment of Proximal Seal Failure in EVAR: A Mid-term Single-Center Experience"],"prefix":"10.1177","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-3276-4438","authenticated-orcid":false,"given":"Jim L.","family":"Mesman","sequence":"first","affiliation":[{"name":"Division of Vascular Surgery, Department of Surgery, University Medical Center Groningen, University of Groningen, Groningen, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7295-9005","authenticated-orcid":false,"given":"Willemina A.","family":"van Veldhuizen","sequence":"additional","affiliation":[{"name":"Division of Vascular Surgery, Department of Surgery, University Medical Center Groningen, University of Groningen, Groningen, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guus","family":"W. van Lammeren","sequence":"additional","affiliation":[{"name":"Division of Vascular Surgery, Department of Surgery, St. Antonius Hospital, Nieuwegein, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jan Albert","family":"Vos","sequence":"additional","affiliation":[{"name":"Department of Radiology, St. Antonius Hospital, Nieuwegein, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9945-910X","authenticated-orcid":false,"given":"Bram","family":"Fioole","sequence":"additional","affiliation":[{"name":"Division of Vascular Surgery, Department of Surgery, Maasstad Hospital, Rotterdam, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jean-Paul P.
