Thoracic endovascular aortic repair (TEVAR) has emerged as the preferred treatment option for patients with BAI. In this study, we compare the longer-term outcomes of patients receiving TEVAR with other treatment options for BAI.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods<\/jats:title>\n                  <jats:p>We conducted a retrospective cohort study using administrative health data on patients with BAI in Ontario, Canada between 2009 and 2020. Patients with BAI and who survived at least 24 hours after hospital admission were identified using diagnostic codes. We classified patients as having received TEVAR, open surgical, hybrid repair, or medical management as their initial treatment approach based on procedure codes. The primary outcome was survival to maximum follow-up. Secondary outcomes included aorta-related mortality or aortic reintervention. Cox\u2019s proportional hazards models were used to estimate the effect of TEVAR on survival.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>427 patients with BAI were followed for a median of 3\u2009years (IQR: 1\u20136 years), with 348 patients (81.5%) surviving. Survival to maximum follow-up did not differ between treatment groups: TEVAR: 79%, surgical repair: 63.6%, hybrid repair: 85.7%, medical management: 83.3% (p=0.10). In adjusted analyses, TEVAR was not associated with improved survival compared with surgical repair (HR: 0.6, 95%\u2009CI: 0.3 to 1.6), hybrid repair (HR: 1.4, 95%\u2009CI: 0.5 to 3.6), or medical management (HR: 1.5, 95%\u2009CI: 0.8 to 2.6). Aortic reinterventions were required in only 2.6% of surviving patients but were significantly more common in the TEVAR group (p&lt;0.01).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>The longer-term survival from BAI appears highly favorable with low rates of reintervention and death in the years after injury, regardless of the initial treatment approach.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Level of evidence<\/jats:title>\n                  <jats:p>IV, Therapeutic study.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1136\/tsaco-2021-000856","type":"journal-article","created":{"date-parts":[[2022,10,24]],"date-time":"2022-10-24T06:00:42Z","timestamp":1666591242000},"page":"e000856","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":7,"title":["Longer-term rates of survival and reintervention after thoracic endovascular aortic repair (TEVAR) for blunt aortic injury: a retrospective population-based cohort study from Ontario, Canada"],"prefix":"10.1136","volume":"7","author":[{"given":"Christopher C D","family":"Evans","sequence":"first","affiliation":[{"name":"Department of Emergency Medicine, Queen's University, Kingston, Ontario, Canada"},{"name":"Institute of Clinical and Evaluative Sciences, Queen's University, Kingston, Ontario, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wenbin","family":"Li","sequence":"additional","affiliation":[{"name":"Institute of Clinical and Evaluative Sciences, Queen's University, Kingston, Ontario, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"Yacob","sequence":"additional","affiliation":[{"name":"Department of Surgery, Queen's University, Kingston, Ontario, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Susan","family":"Brogly","sequence":"additional","affiliation":[{"name":"Institute of Clinical and Evaluative Sciences, Queen's University, Kingston, Ontario, Canada"},{"name":"Department of Surgery, Queen's University, Kingston, Ontario, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2022,3,24]]},"reference":[{"key":"2025082410161790000_7.1.e000856.1","unstructured":"Peden M , McGee K , Sharma G .
