Case Report: An 82-year-old man was treated for a 47-mm abdominal aortic aneurysm associated with a 35-mm left common iliac artery aneurysm using an Ovation Abdominal Stent Graft System. Correct endograft placement was documented at 3-month follow-up. Seven months after the repair, the patient was admitted to the emergency department with acute left inguinal pain. Computed tomography showed aneurysm sac enlargement (57 mm) and a contained rupture of the left common iliac artery due to a late type Ia endoleak. The endoleak was embolized with coils and thrombin via a transcaval approach. Sac shrinkage without signs of endoleak was observed at 12-month follow-up. Conclusion: In this case, late endograft failure with sealing ring collapse created an inflow channel into the aneurysm sac, with massive type Ia endoleak.<\/jats:p>","DOI":"10.1177\/1526602815579898","type":"journal-article","created":{"date-parts":[[2015,5,19]],"date-time":"2015-05-19T14:51:06Z","timestamp":1432047066000},"page":"426-430","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":10,"title":["Inexplicable
