Although endovascular aneurysm repair (EVAR) and thoracic endovascular aortic repair (TEVAR) are increasingly being performed, various complications can occur. We report a case of collapse of a stent graft, which was used to repair an abdominal aortic aneurysm (AAA) after TEVAR for thoracic aortic aneurysm (TAA). A 72-year-old man with a 77\u2009mm AAA and 60\u2009mm TAA underwent EVAR and a TEVAR 2 months later, respectively. CT performed after the TEVAR showed thoracic aorta dissection with associated AAA stent graft collapse. The graft collapsed was due to superior mesenteric artery obstruction. An emergency TEVAR was performed, and the procedure improved the collapsed graft; however, the endoleak of the AAA stent graft persisted. The AAA expanded over several days, warranting an open repair. Our case provides an insight into the cautionary indications for endovascular therapy.<\/jats:p>","DOI":"10.1136\/bcr-2021-246798","type":"journal-article","created":{"date-parts":[[2021,12,9]],"date-time":"2021-12-09T11:35:28Z","timestamp":1639049728000},"page":"e246798","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Stent graft in abdominal aortic aneurysm collapsed suddenly after thoracic endovascular aortic repair"],"prefix":"10.1136","volume":"14","author":[{"given":"Sho","family":"Takagi","sequence":"first","affiliation":[{"name":"Department of Cardiovascular Surgery, Toyohashi Heart Center, Toyohashi, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoshihiro","family":"Goto","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, Toyohashi Heart Center, Toyohashi, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Junji","family":"Yanagisawa","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, Toyohashi Heart Center, Toyohashi, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Akio","family":"Nakasu","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, Toyohashi Heart Center, Toyohashi, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2021,12,9]]},"reference":[{"key":"2025082800480392000_14.12.e246798.1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2005.11.017"},{"key":"2025082800480392000_14.12.e246798.2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa0707348"},{"key":"2025082800480392000_14.12.e246798.3","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2009.03.060"},{"key":"2025082800480392000_14.12.e246798.4","doi-asserted-by":"crossref","first-page":"99","DOI":"10.1186\/s40792-015-0096-3","article-title":"Emergency thoracic aortic stent grafting for acute complicated type B aortic dissection after a previous abdominal endovascular aneurysm repair","volume":"1","author":"Yoshiga","year":"2015","journal-title":"Surg Case Rep"},{"key":"2025082800480392000_14.12.e246798.5","first-page":"135","article-title":"Long-Term safety and efficacy of endovascular abdominal aortic aneurysm repair","volume":"9","author":"Propper","year":"2013","journal-title":"Vasc Health Risk Manag"},{"key":"2025082800480392000_14.12.e246798.6","doi-asserted-by":"crossref","first-page":"92","DOI":"10.3400\/avd.ar.20-00162","article-title":"The outcomes of endovascular aneurysm repair in Japan in 2017: a report from the Japanese Committee for Stentgraft management","volume":"14","author":"Hoshina","year":"2021","journal-title":"Ann Vasc Dis"},{"key":"2025082800480392000_14.12.e246798.7","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM199905203402004"},{"key":"2025082800480392000_14.12.e246798.8","doi-asserted-by":"crossref","first-page":"76","DOI":"10.1016\/j.jvs.2015.12.055","article-title":"Conversion from endovascular to open abdominal aortic aneurysm repair","volume":"64","author":"Ultee","year":"2016","journal-title":"J Vasc Surg"},{"key":"2025082800480392000_14.12.e246798.9","doi-asserted-by":"crossref","first-page":"157","DOI":"10.1177\/1708538116651020","article-title":"Single-Center experience with simultaneous thoracic endovascular aortic repair and abdominal endovascular aneurysm repair","volume":"25","author":"Zeng","year":"2017","journal-title":"Vascular"},{"key":"2025082800480392000_14.12.e246798.10","first-page":"273","article-title":"Simultaneous endovascular stent-graft repair of descending thoracic and abdominal aortic pathologies.
