Recently, endovascular aneurysm repair (EVAR) has been expanded among patients with complex AAA, which involves visceral branches in the upper abdominal aortic. However, outcomes of EVAR for complex AAA in patients with PAS have not been examined. This study aimed to investigate the impact of PAS on 30-day outcomes in EVAR for complex AAA.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Patients who underwent EVAR for complex AAA were identified in ACS-NSQIP targeted database from 2012 to 2022. Complex AAA was defined as juxtarenal, suprarenal, or pararenal proximal extent, Type IV thoracoabdominal aneurysm, or aneurysms treated with Zenith Fenestrated endograft. Patients with age less than 18 years, ruptured AAA with or without hypotension, acute intraoperative conversion to open, and emergency presentation were excluded. Multivariable logistic regression was used to compare 30-day postoperative outcomes of patients with and without PAS. Demographics, baseline characteristics, aneurysm diameter, indication for surgery, proximal and distant aneurysm extent, anesthesia, and concomitant procedures were adjusted.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      There were 515 (28.34%) and 1302 (71.66%) patients with and without PAS, respectively, who underwent EVAR for complex AAA. Patients with and without PAS had comparable 30-day mortality (3.11% vs 3.00%, aOR = 0.766, 95 CI = 0.407\u20131.442,\n                      <jats:italic>p<\/jats:italic>\n                      = .41). Organ system complications including cardiac complications, stroke, pulmonary complications, and renal complications were comparable between patients with and without PAS. All other 30-day outcomes were similar between groups. However, patients with PAS had higher 30-day readmission rate (11.65% vs 7.14%, aOR = 1.634, 95 CI = 1.145\u20132.331,\n                      <jats:italic>p<\/jats:italic>\n                      = .01).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>While PAS has high prevalence among patients undergoing EVAR for complex AAA, it does not impact 30-day mortality and morbidities. Thus, EVAR for complex AAA can be considered safe for patients with PAS in terms of short-term outcomes, despite the long-term prognosis in these patients being needed in further studies.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/17085381241256442","type":"journal-article","created":{"date-parts":[[2024,5,22]],"date-time":"2024-05-22T06:10:16Z","timestamp":1716358216000},"page":"541-547","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Prior abdominal surgery is not associated with 30-day mortality or morbidities after endovascular repair of complex abdominal aortic aneurysm"],"prefix":"10.1177","volume":"33","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1691-6278","authenticated-orcid":false,"given":"Renxi","family":"Li","sequence":"first","affiliation":[{"name":"School of Medicine and Health Sciences, The George Washington University, Washington, DC, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anton","family":"Sidawy","sequence":"additional","affiliation":[{"name":"Department of Surgery, The George Washington University Hospital, Washington, DC, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bao-Ngoc","family":"Nguyen","sequence":"additional","affiliation":[{"name":"Department of Surgery, The George Washington University Hospital, Washington, DC, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2024,5,22]]},"reference":[{"key":"e_1_3_5_2_2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0081260"},{"key":"e_1_3_5_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2020.03.046"},{"key":"e_1_3_5_4_2","doi-asserted-by":"publisher","DOI":"10.1067\/mva.2002.123763"},{"key":"e_1_3_5_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2017.10.044"},{"key":"e_1_3_5_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2014.01.007"},{"key":"e_1_3_5_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2017.01.028"},{"key":"e_1_3_5_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2004.12.048"},{"key":"e_1_3_5_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2011.10.094"},{"key":"e_1_3_5_10_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa1207481"},{"key":"e_1_3_5_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2016.10.123"},{"key":"e_1_3_5_12_2","doi-asserted-by":"publisher","DOI":"10.1097\/00000658-198606000-00011"},{"key":"e_1_3_5_13_2","doi-asserted-by":"publisher","DOI":"10.1053\/ejvs.1999.0924"},{"issue":"2","key":"e_1_3_5_14_2","first-page":"169","article-title":"The influence of prior abdominal operations on conversion and complication rates in laparoscopic colorectal surgery","volume":"10","author":"Franko J","year":"2006","unstructured":"Franko J, O\u2019Connell BG, Mehall JR, et al.
