Endovascular aneurysm repair (EVAR) is a minimally invasive treatment for abdominal aortic aneurysms (AAAs). Common complications include endoleaks, which are continued blood flow into the aneurysm sac external to the graft. Type I endoleaks occur proximally or distally, resulting from inadequate seals between the graft and artery. Type III endoleaks stem from defects between components in modular grafts or fabric tears. Re-intervention is indicated for type I and III endoleaks due to pressurization of the aneurysm sac resulting in a high risk of rupture. A 68 year-old man presented with an infrarenal AAA and underwent EVAR. He developed a late type I endoleak requiring reintervention with a stent graft cuff, and later presented with a recurrent type I endoleak and type IIIb endoleak. The AAA increased in size to 18 cm with contained rupture, requiring emergent endograft explantation and repair with a bifurcated Dacron graft. His postoperative course was uncomplicated.
