Although several studies have suggested that T2ELs are related to an increased risk of aneurysm sac growth and subsequent rupture, the exact role that T2ELs play in long-term outcomes remains debatable. Understanding the pathophysiology, diagnostic modalities, and management options of T2ELs is important for patients\u2019 safety and proper resource utilization. While conservative management may be suitable for asymptomatic patients with a stable aneurysm size, interventional approaches, including transarterial embolization, direct sac puncture embolization and open conversion have been described for patients with persistent T2EL associated with sac expansion. However, more research is needed to better determine the clinical benefit of such interventions. A thorough evaluation of all endoleak types before T2EL treatment would be reasonable for patients with T2ELs associated with sac expansion. Further studies are needed to refine treatment strategies aimed at minimizing T2EL-related complications. Collaborative efforts among vascular specialists, radiologists, and researchers are of paramount importance to address this ongoing clinical challenge.<\/jats:p>","DOI":"10.3390\/jcm13144250","type":"journal-article","created":{"date-parts":[[2024,7,22]],"date-time":"2024-07-22T14:45:53Z","timestamp":1721659553000},"page":"4250","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Understanding Type II Endoleak: A Harmless Imaging Finding or a Silent Threat?"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-7317-4655","authenticated-orcid":false,"given":"Georgios","family":"Koudounas","sequence":"first","affiliation":[{"name":"Vascular Unit, 5th Department of Surgery, Aristotle University Medical School, Hippokratio Hospital, 54642 Thessaloniki, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1942-911X","authenticated-orcid":false,"given":"Stefanos","family":"Giannopoulos","sequence":"additional","affiliation":[{"name":"Division of Vascular and Endovascular Surgery, Department of Surgery, Stony Brook University Hospital, Stony Brook, NY 11794, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7863-647X","authenticated-orcid":false,"given":"Nektarios","family":"Charisis","sequence":"additional","affiliation":[{"name":"Department of Radiology, Stony Brook University Hospital, Stony Brook, NY 11794, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nicos","family":"Labropoulos","sequence":"additional","affiliation":[{"name":"Division of Vascular and Endovascular Surgery, Department of Surgery, Stony Brook University Hospital, Stony Brook, NY 11794, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,7,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"385","DOI":"10.1016\/j.ejvs.2019.11.030","article-title":"Editor\u2019s Choice\u2014Endovascular vs. Open Repair for Abdominal Aortic Aneurysm: Systematic Review and Meta-analysis of Updated Peri-operative and Long Term Data of Randomised Controlled Trials","volume":"59","author":"Antoniou","year":"2020","journal-title":"Eur.
