This study sought to determine the frequency and nature of intraoperative endoleaks and their impact on postoperative endoleak-related events. Methods: A retrospective chart review was performed of all patients who underwent EVAR at our institution. The impact of intraoperative endoleaks on postoperative endoleak rates and endoleak-related reintervention rates were assessed. Results: From December 18, 1996, to May 21, 2003, 241 patients underwent EVAR. An endoleak was observed during 126 (52.3%) procedures. Type I endoleaks were observed in 63 (26.1%) cases: 35 proximal and 31 distal endoleaks (3 cases at both attachments). Angioplasty, additional cuff placement, or stenting corrected 59 (89.4%) of these endoleaks. A total of 71 type II intraoperative endoleaks (29.5%) and 8 type IV endoleaks (3.3%) were observed without any attempted corrective maneuvers. Ten type III endoleaks (4.2%) occurred but all resolved with angioplasty or additional cuff placement. In all, 86 (35.7%) endoleaks persisted on completion angiogram. Patients with a type I or type II intraoperative endoleak were more likely to have an endoleak at 1.5 years (31.4% vs. 21.6%, P = .018). Reinterventions were required more often after an intraoperative type I endoleak (10% vs. 4%, P = .003). Patients with intraoperative endoleaks demonstrated a trend toward less postoperative aneurysm diameter reduction at 2 years (43.8% vs. 74.5%, P = .104). Conclusion: The presence of a type I or a type II endoleak during EVAR significantly increases the likelihood of a postoperative endoleak and should prompt a high degree of suspicion during follow-up. <\/jats:p>","DOI":"10.1177\/1538574409333581","type":"journal-article","created":{"date-parts":[[2009,4,8]],"date-time":"2009-04-08T01:31:59Z","timestamp":1239154319000},"page":"352-359","source":"Crossref","is-referenced-by-count":29,"title":["Intraoperative Endoleak During EVAR: Frequency, Nature, and Significance"],"prefix":"10.1177","volume":"43","author":[{"given":"Sergio M.","family":"Sampaio","sequence":"first","affiliation":[{"name":"Eastern Virginia Medical School, Norfolk, Virginia"}]},{"given":"Susanna H.","family":"Shin","sequence":"additional","affiliation":[{"name":"Mayo Clinic, Rochester, MN"}]},{"given":"Jean M.","family":"Panneton","sequence":"additional","affiliation":[{"name":"Eastern Virginia Medical School, Norfolk, Virginia,"}]},{"given":"James C.","family":"Andrews","sequence":"additional","affiliation":[{"name":"Mayo Clinic, Rochester, MN"}]},{"given":"Thomas C.","family":"Bower","sequence":"additional","affiliation":[{"name":"Mayo Clinic, Rochester, MN"}]},{"given":"Kenneth J.","family":"Cherry","sequence":"additional","affiliation":[{"name":"University of Virginia, Charlottesville, Virginia"}]},{"given":"Audra A.","family":"Duncan","sequence":"additional","affiliation":[{"name":"Mayo Clinic, Rochester, MN"}]},{"given":"Manju","family":"Kalra","sequence":"additional","affiliation":[{"name":"Mayo Clinic, Rochester, MN"}]},{"given":"Peter","family":"Gloviczki","sequence":"additional","affiliation":[{"name":"Mayo Clinic, Rochester, MN"}]}],"member":"179","published-online":{"date-parts":[[2009,4,7]]},"reference":[{"doi-asserted-by":"publisher","key":"atypb1","DOI":"10.1007\/BF02015271"},{"doi-asserted-by":"publisher","key":"atypb2","DOI":"10.1016\/S0741-5214(98)70224-1"},{"doi-asserted-by":"publisher","key":"atypb3","DOI":"10.1016\/S0741-5214(98)70293-9"},{"doi-asserted-by":"publisher","key":"atypb4","DOI":"10.1067\/mva.2002.118823"},{"doi-asserted-by":"publisher","key":"atypb5","DOI":"10.1177\/152660280000700401"},{"doi-asserted-by":"publisher","key":"atypb6","DOI":"10.1007\/s10016-001-0327-x"},{"doi-asserted-by":"publisher","key":"atypb7","DOI":"10.1016\/S0741-5214(97)70327-6"},{"doi-asserted-by":"publisher","key":"atypb8","DOI":"10.1053\/ejvs.2000.1341"},{"doi-asserted-by":"publisher","key":"atypb9","DOI":"10.1016\/S0009-9260(98)80151-7"},{"doi-asserted-by":"publisher","key":"atypb10","DOI":"10.1177\/152660280100800513"},{"doi-asserted-by":"publisher","key":"atypb11","DOI":"10.1007\/s10016-005-0002-8"},{"doi-asserted-by":"publisher","key":"atypb12","DOI":"10.1007\/s10016-004-0100-z"},{"doi-asserted-by":"publisher","key":"atypb13","DOI":"10.1067\/mva.2002.123763"},{"key":"atypb14","doi-asserted-by":"crossref","first-page":"187","DOI":"10.1177\/153100350201500213","volume":"15","author":"Panneton JM","year":"2002","journal-title":"Perspect Vasc Surg Endovasc Ther"},{"doi-asserted-by":"publisher","key":"atypb15","DOI":"10.1067\/mva.2000.108278"},{"doi-asserted-by":"publisher","key":"atypb16","DOI":"10.1016\/S1078-5884(98)80236-0"},{"doi-asserted-by":"publisher","key":"atypb17","DOI":"10.1067\/mva.2001.112232"},{"doi-asserted-by":"publisher","key":"atypb18","DOI":"10.1148\/radiology.218.2.r01fe13477"},{"doi-asserted-by":"publisher","key":"atypb19","DOI":"10.1067\/mva.2000.110172"},{"doi-asserted-by":"publisher","key":"atypb20","DOI":"10.1583\/1074-6218(1998)005<0305:TIATIE>2.0.CO;2"},{"doi-asserted-by":"publisher","key":"atypb21","DOI":"10.1067\/mva.2002.126085"}],"container-title":["Vascular and Endovascular Surgery"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1538574409333581","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1538574409333581","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,3,1]],"date-time":"2025-03-01T15:32:54Z","timestamp":1740843174000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/1538574409333581"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,4,7]]},"references-count":21,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2009,8]]}},"alternative-id":["10.1177\/1538574409333581"],"URL":"https:\/\/doi.org\/10.1177\/1538574409333581","relation":{},"ISSN":["1538-5744","1938-9116"],"issn-type":[{"type":"print","value":"1538-5744"},{"type":"electronic","value":"1938-9116"}],"subject":[],"published":{"date-parts":[[2009,4,7]]}}}
