Abstract
Junctional component uncoupling of an AFX endograft is a rare but catastrophic cause of late type IIIA endoleak after endovascular aortic repair. A 74-year-old man presented with abdominal pain and shock 2 years and 8 months after endovascular aortic repair with AFX2, despite progressive sac regression on surveillance imaging. Computed tomography revealed aneurysm rupture due to a massive type IIIA endoleak with proximal component uncoupling. Emergency relining was performed; however, recurrent type III endoleaks required conversion to an aortouni-iliac configuration with femoral-femoral bypass. Retrospective imaging demonstrated progressive proximal intercomponent angle and reduced component overlap, suggesting longitudinal aortic remodeling as a mechanism of uncoupling.
