Abstract

|
Addressing the high incidence of late type III endoleaks in previous AFX models, Endologix upgraded the device material and updated its recommendation regarding component overlap. However, whether upgraded AFX2 models are safe for endoleaks remains controversial. Here we report a case of a 67-year-old male with an AFX2-implanted abdominal aortic aneurysm experiencing a delayed type IIIa endoleak. Aneurysmal sac enlargement occurred 36 months post-endovascular aneurysm repair (EVAR), with a computed tomography scan at 52 months revealing component overlap loss and a significant type IIIa endoleak. We performed endograft explantation and endoaneurysmal aorto-bi-iliac interposition grafting.
Our findings suggest that sufficient component overlap is necessary when using an AFX2 endograft outside the manufacturer’s instructions for use to prevent late type IIIa endoleaks. Moreover, patients who undergo EVAR with AFX2 for tortuous large aortic aneurysms should be carefully monitored for conformational changes.
