Bovine pericardium offers a customisable, off-the-shelf option for in situ reconstruction using biological material. We evaluate long-term outcomes following emergency bovine pericardium neo-aorta reconstruction in infected aortic fields.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Prospectively collected data for all patients treated with bovine pericardium neo-aorta reconstructions from 2018 to date were analysed. The surgical approach included resection of the infected aortic segment, explantation of previous grafts and\/or stents, and reconstruction of the neo-aorta using a bovine pericardium sheet. Data collected included patient demographics, comorbidities, clinical presentation, previous interventions, blood tests, complications, length of antibiotic treatment and long-term survival. All neo-aortas were enrolled in an annual ultrasound surveillance programme to monitor for aneurysmal degeneration.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Fifteen aortic reconstructions were performed. The most common indication was aorto-enteric fistulas (n = 7), followed by infected aortic grafts (n = 4), mycotic aneurysms (n = 3) and one contaminated field due to emergency colectomy. Median follow-up was 34 months (range 9\u201384). Thirty-day mortality was 7%, with another 7% at 10 weeks. Antibiotic-free survival rate was 86%. One patient (7%) required long-term antibiotics post-partial endovascular aneurysm repair explant. Complications included one graft occlusion with limb loss and one case of end-stage renal failure. No aneurysmal degeneration was identified during follow-up.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Bovine pericardial neo-aorta reconstructions have shown excellent long-term resistance to infections and very good durability. Our data add to growing evidence supporting off-the-shelf use of bovine pericardium in emergency aortic reconstruction. Larger numbers through multicentre studies or special registries would help support more regular use.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1308\/rcsann.2025.0116","type":"journal-article","created":{"date-parts":[[2026,1,12]],"date-time":"2026-01-12T11:19:46Z","timestamp":1768216786000},"page":"465-468","source":"Crossref","is-referenced-by-count":0,"title":["Long-term outcomes of bovine pericardium neo-aortic reconstructions in infected vascular fields"],"prefix":"10.1308","volume":"108","author":[{"given":"M","family":"Bakheet","sequence":"first","affiliation":[{"name":"Lancashire Teaching Hospitals NHS Foundation Trust","place":["UK"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"T","family":"Babiker","sequence":"additional","affiliation":[{"name":"Lancashire Teaching Hospitals NHS Foundation Trust","place":["UK"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"I","family":"Zeynali","sequence":"additional","affiliation":[{"name":"Lancashire Teaching Hospitals NHS Foundation Trust","place":["UK"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"B","family":"Rawshdeh","sequence":"additional","affiliation":[{"name":"Lancashire Teaching Hospitals NHS Foundation Trust","place":["UK"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"G","family":"Riding","sequence":"additional","affiliation":[{"name":"Lancashire Teaching Hospitals NHS Foundation Trust","place":["UK"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M","family":"Banihani","sequence":"additional","affiliation":[{"name":"Lancashire Teaching Hospitals NHS Foundation Trust","place":["UK"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"171","reference":[{"key":"C1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2013.01.047"},{"key":"C2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2003.12.040"},{"key":"C3","first-page":"675","volume":"18","author":"Swain TW","year":"2004","journal-title":"Ann Vasc Surg"},{"key":"C4","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejvs.2019.10.016"},{"key":"C5","first-page":"291","volume":"66","author":"Melloni A","year":"2025","journal-title":"J Cardiovasc Surg (Torino)"},{"key":"C6","doi-asserted-by":"publisher","DOI":"10.1016\/j.avsg.2016.07.098"},{"key":"C7","doi-asserted-by":"publisher","DOI":"10.1016\/j.avsg.2024.01.015"},{"key":"C8","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2019.04.485"},{"key":"C9","doi-asserted-by":"publisher","DOI":"10.1093\/bjs\/znad159"},{"key":"C10","doi-asserted-by":"publisher","DOI":"10.1093\/icvts\/ivz105"},{"key":"C11","doi-asserted-by":"publisher","DOI":"10.1016\/j.athoracsur.2018.03.012"},{"key":"C12","doi-asserted-by":"publisher","DOI":"10.1016\/j.avsg.2017.02.021"},{"key":"C13","doi-asserted-by":"publisher","DOI":"10.1016\/j.avsg.2023.11.037"},{"key":"C14","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2025.03.182"},{"key":"C15","first-page":"33","volume":"68","author":"Weiss S","year":"2024","journal-title":"Eur J Vasc Endovasc Surg"}],"container-title":["The Annals of The Royal College of Surgeons of England"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/publishing.rcseng.ac.uk\/doi\/pdf\/10.1308\/rcsann.2025.0116","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,7,1]],"date-time":"2026-07-01T10:11:19Z","timestamp":1782900679000},"score":1,"resource":{"primary":{"URL":"https:\/\/publishing.rcseng.ac.uk\/doi\/10.1308\/rcsann.2025.0116"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,7]]},"references-count":15,"journal-issue":{"issue":"6","published-print":{"date-parts":[[2026,7]]}},"alternative-id":["10.1308\/rcsann.2025.0116"],"URL":"https:\/\/doi.org\/10.1308\/rcsann.2025.0116","relation":{},"ISSN":["0035-8843","1478-7083"],"issn-type":[{"value":"0035-8843","type":"print"},{"value":"1478-7083","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,7]]}}}
