Intraoperative cCTA findings were compared with postoperative CTA on day 1 in 28 patients. Discrepancies in findings between the two CTA, any adjunctive corrective maneuvers, time required for cCTA imaging, radiation dose exposure, and reintervention rates were recorded.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Intraoperative cCTA was technically successful in all patients (100%). Immediate corrective maneuvers were performed in 2 (7%) patients based on cCTA findings. Discrepancies between intraoperative and postoperative CTA were observed in 4\/28 (14%) patients, all related to early-phase endoleaks. No discrepancies were found regarding endograft positioning or procedural complications. Mean effective dose from intraoperative cCTA was 11.3 mSv (interquartile range = 8.0\u201312.8).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Intraoperative cCTA during f-bEVAR was feasible and achieved a high technical success rate. It provided reliable visualization of endograft architecture and intraprocedural complications, but cCTA did not identify the same number of early-phase endoleaks as postoperative CTA. While the routine use of intraoperative cCTA may offer limited patient benefit, it can be a useful adjunct in challenging cases.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/02841851251381345","type":"journal-article","created":{"date-parts":[[2025,10,15]],"date-time":"2025-10-15T17:52:51Z","timestamp":1760550771000},"page":"43-49","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Intra-arterial computed tomography angiography during fenestrated and branched endovascular aortic repair"],"prefix":"10.1177","volume":"67","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3540-0752","authenticated-orcid":false,"given":"Anne Marte","family":"Schr\u00f8der-Aasen","sequence":"first","affiliation":[{"name":"Oslo University Hospital"},{"name":"University of Oslo"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ulrik","family":"Carling","sequence":"additional","affiliation":[{"name":"Oslo University Hospital"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Margrethe Kallestad","family":"Rasmussen","sequence":"additional","affiliation":[{"name":"Oslo University Hospital"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0447-1152","authenticated-orcid":false,"given":"Eric","family":"Dorenberg","sequence":"additional","affiliation":[{"name":"Oslo University Hospital"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2025,10,15]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejvs.2016.06.005"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejvs.2023.11.002"},{"key":"e_1_3_2_4_2","first-page":"389\u2013397","article-title":"Predicting features of visceral stent failure in fenestrated endovascular aortic aneurysm repair","author":"Mancuso E","year":"2025","unstructured":"Mancuso E, Bootun R, Stather PW, et al.
