Endovascular aneurysm repair (EVAR) has been established as a safe and effective treatment modality for infrarenal abdominal aortic aneurysms. Endograft migration resulting in a proximal type I endoleak can be one of the most difficult challenges following EVAR. Often, this precludes endovascular treatment and necessitates conversion to open surgical repair. We report a case of a high-risk patient who presented with impending abdominal aortic aneurysm rupture as a result of endograft migration following EVAR performed 5 years prior. The endograft had folded over on itself within the aneurysm sac and was successfully repaired using a total endovascular approach.
血管内动脉瘤修复术（EVAR）已被确立为治疗肾下腹部主动脉瘤的一种安全有效的治疗方式。内移导致的近端 I 型内漏可能是 EVAR 后最具挑战性的问题之一。通常，这排除了血管内治疗的可能性，需要转为开放手术修复。我们报告了一例高危患者的病例，该患者在 5 年前接受 EVAR 治疗后因内移导致即将发生腹主动脉瘤破裂。内移的移植物在动脉瘤囊内自行折叠，通过完全血管内方法成功修复。
