Previous trials confirm that elective endovascular aneurysm repair (EVAR) is an effective intervention for AAA. However, few elderly patients were recruited into randomized trials, whereas in contemporary clinical practice, elective repair is commonly performed on octogenarians. We evaluated the safety and outcome of elective EVAR in elderly patients to inform clinical practice and vascular service provision.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>A systematic review and meta-analysis of studies reporting risk of complications and death in patients undergoing elective EVAR was performed (PROSPERO CRD: 42022308423). Observational studies and interventional arms of randomized trials were included if the outcome rates or raw data were provided. Primary outcome was 30-day mortality. Secondary outcomes were longer-term mortality, 30-day major adverse events, and aneurysm-related mortality. Primary and secondary outcomes were compared between octogenarians and non-octogenarians. Exclusion criteria were emergency procedures, non-infrarenal aneurysms, and lack of octogenarian data.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>A total of 41 studies were eligible from 10\u2009099 citations, including 10 national and 5 international registries, 26 retrospective studies, and our own prospective cohort. The analysis included 208\u2009997 non-octogenarians (mean age=70.19 [SD=0.62]) and 106\u2009188 octogenarians (mean age=83.75 [SD=0.35]). The 30-day mortality post-elective EVAR was higher in octogenarians (1.08% in non-octogenarians, 2.31% in octogenarians, odds ratio [OR]=2.27 [2.08-2.47], p&lt;0.0001). Linear regression demonstrated a 0.83% increase in 30-day mortality for every 10-year age increase above 60 years old. Mortality for octogenarians increased significantly during follow-up: 11.35% (OR=1.87 [1.65-2.13], p&lt;0.001), 22.80% (OR=1.89 [1.52-2.35], p&lt;0.001), 32.00% (OR=1.98 [1.66-2.37], p&lt;0.001), 47.53%, and 51.08% (OR=2.40 [1.90-3.03], p&lt;0.001) at 1-through-5-year follow-up, respectively. The 30-day major adverse events after elective EVAR were higher in octogenarians (OR=1.75-2.83, p&lt;0.001).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>Octogenarians experience higher but acceptable peri-operative morbidity and mortality compared with younger patients. However, 3-year to 5-year survival is very low among octogenarians. Our findings challenge the notion of routine intervention in elderly patients and support very careful selection for elective EVAR. Many octogenarians with peri-threshold (&lt;6 cm) AAAs may derive no benefit from EVAR due to limited 3-year to 5-year overall survival and low risk of aneurysm rupture with conservative management. An adjusted threshold for intervention in octogenarians may be warranted.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Clinical Impact<\/jats:title>\n                    <jats:p>Octogenarians with infra-renal AAA are increasingly managed with elective EVAR. Previous studies have demonstrated that EVAR is safer than open repair for octogenarians, with lower peri-operative mortality and major adverse events. However, randomised trials, on which much of contemporary evidence is based, recruited a relatively younger population of participants. This systematic review and meta-analysis provides a contemporary synthesis of the literature comparing outcomes in octogenarians to younger patients. The results of this analysis, together with low rupture rates amongst octogenarians in existing literature, question the benefit of routine elective intervention for peri-threshold aneurysms and an adjusted threshold for intervention in octogenarians may be warranted.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/15266028241283669","type":"journal-article","created":{"date-parts":[[2024,9,26]],"date-time":"2024-09-26T14:17:58Z","timestamp":1727360278000},"page":"584-597","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":10,"title":["The Safety and Outcomes of Elective Endovascular Aneurysm Repair in the Elderly: A Systemic Review and Meta-Analysis"],"prefix":"10.1177","volume":"33","author":[{"ORCID":"https:\/\/orcid.org\/0009-0009-5456-7233","authenticated-orcid":false,"given":"Sebastian","family":"Vaughan-Burleigh","sequence":"first","affiliation":[{"name":"Department of Vascular Surgery, Oxford University Hospitals NHS Trust, Oxford, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ya Yuan Rachel","family":"Leung","sequence":"additional","affiliation":[{"name":"Department of Vascular Surgery, Oxford University Hospitals NHS Trust, Oxford, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Faaraz","family":"Khan","sequence":"additional","affiliation":[{"name":"Department of Vascular Surgery, Oxford University Hospitals NHS Trust, Oxford, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Patrick","family":"Lintott","sequence":"additional","affiliation":[{"name":"Department of Vascular Surgery, Oxford University Hospitals NHS Trust, Oxford, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dominic P.
