The COVID-19 pandemic has significantly affected surgical and interventional radiology services worldwide. We aimed to review the impact COVID-19 has caused to the management of acute dialysis access thrombosis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>We conducted a single centre retrospective review of outcomes of patients with arteriovenous fistula and arteriovenous graft thrombosis between March and May 2020, which coincided with the first peak of the COVID-19 pandemic in London, and a similar period in the previous year, March\u2013May 2019. Outcomes in both cohorts of patients were compared, including attempts at salvage, salvage success, 1-month patency rates after salvage and subsequent surgery on the same access. We also analysed the use of tunnelled haemodialysis lines (THL), either due to failed salvage attempts or when salvage was not attempted.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>There was a similar incidence of access thrombosis in both periods (26 cases in 2019, 38 in 2020). There were 601 patients dialysing via an arteriovenous fistula or graft in 2019, and 568 patients in 2020. Access salvage, when attempted, had similar success rates and 1-month patency (salvage success 74% vs 80%, p\u2009=\u20090.39; 1-month patency 55% vs 62%, p\u2009=\u20090.69). The proportion of patients where access salvage was not attempted and a THL inserted was significantly higher in 2020 compared to 2019 (32% vs 4%, p\u2009=\u20090.007). There were more patients who subsequently had surgery to salvage or revise the same access in 2019 compared to 2020 (62% vs 13%, p\u2009&lt;\u20090.001).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>During the peak of the COVID-19 pandemic, there were fewer attempts at access salvage. This was a conscious decision due to increased pressure on the healthcare system, access to emergency interventional radiology or operative theatres and the perceived risk\/benefit ratio of access salvage. The long-term effects of this change in practice remain unknown.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/11297298211045578","type":"journal-article","created":{"date-parts":[[2021,9,18]],"date-time":"2021-09-18T07:46:12Z","timestamp":1631951172000},"page":"660-665","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":4,"title":["The management of dialysis access thrombosis during the COVID-19 pandemic"],"prefix":"10.1177","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0817-9362","authenticated-orcid":false,"given":"Christopher","family":"Seet","sequence":"first","affiliation":[{"name":"Department of Nephrology and Transplantation, The Royal London Hospital, Bart\u2019s Health NHS Trust, London, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ben","family":"Lindsey","sequence":"additional","affiliation":[{"name":"Department of Nephrology and Transplantation, The Royal London Hospital, Bart\u2019s Health NHS Trust, London, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rajesh","family":"Sivaprakasam","sequence":"additional","affiliation":[{"name":"Department of Nephrology and Transplantation, The Royal London Hospital, Bart\u2019s Health NHS Trust, London, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kieran","family":"McCafferty","sequence":"additional","affiliation":[{"name":"Department of Nephrology and Transplantation, The Royal London Hospital, Bart\u2019s Health NHS Trust, London, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Suzanne","family":"Forbes","sequence":"additional","affiliation":[{"name":"Department of Nephrology and Transplantation, The Royal London Hospital, Bart\u2019s Health NHS Trust, London, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mohammed Rashid","family":"Akhtar","sequence":"additional","affiliation":[{"name":"Department of Interventional Radiology, The Royal London Hospital, Bart\u2019s Health NHS Trust, London, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Muhammad","family":"Khurram","sequence":"additional","affiliation":[{"name":"Department of Nephrology and Transplantation, The Royal London Hospital, Bart\u2019s Health NHS Trust, London, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ismail H","family":"Mohamed","sequence":"additional","affiliation":[{"name":"Department of Nephrology and Transplantation, The Royal London Hospital, Bart\u2019s Health NHS Trust, London, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2021,9,18]]},"reference":[{"key":"bibr1-11297298211045578","doi-asserted-by":"publisher","DOI":"10.1053\/j.ajkd.2019.12.001"},{"key":"bibr2-11297298211045578","doi-asserted-by":"publisher","DOI":"10.2215\/CJN.03140313"},{"key":"bibr3-11297298211045578","doi-asserted-by":"publisher","DOI":"10.1007\/s13239-017-0320-3"},{"key":"bibr4-11297298211045578","doi-asserted-by":"publisher","DOI":"10.1111\/sdi.12255"},{"key":"bibr5-11297298211045578","doi-asserted-by":"publisher","DOI":"10.1016\/j.eclinm.2020.100639"},{"key":"bibr6-11297298211045578","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2018.10.102"},{"key":"bibr7-11297298211045578","doi-asserted-by":"publisher","DOI":"10.1111\/hdi.12883"},{"key":"bibr8-11297298211045578","doi-asserted-by":"publisher","DOI":"10.1038\/s41581-020-00381-4"},{"key":"bibr9-11297298211045578","doi-asserted-by":"publisher","DOI":"10.1053\/j.ajkd.2021.01.003"},{"key":"bibr10-11297298211045578","doi-asserted-by":"publisher","DOI":"10.1093\/ndt\/gfab028."},{"key":"bibr11-11297298211045578","doi-asserted-by":"publisher","DOI":"10.2215\/CJN.03180321"},{"key":"bibr12-11297298211045578","doi-asserted-by":"publisher","DOI":"10.1093\/ndt\/gfaa069"},{"key":"bibr13-11297298211045578","doi-asserted-by":"publisher","DOI":"10.1177\/11297298211021253."},{"key":"bibr14-11297298211045578","doi-asserted-by":"crossref","first-page":"1440","DOI":"10.1002\/bjs.11646","volume":"107","author":"Collaborative COVIDSURG","year":"2020","journal-title":"Br J Surg"},{"key":"bibr15-11297298211045578","unstructured":"American College of Surgeons.
