Abstract
An 87-year-old man was treated for abdominal aortic aneurysm (AAA) with an excluder stent graft. However, re-onset type II endoleak with significant aneurysm enlargement was observed 17 months after the procedure. Instead of embolization to the lumbar artery and inferior mesenteric artery (IMA), the diameter of his aneurysm increased. Finally, late open conversion was successfully performed with an infrarenal aortic cross-clamp, complete stent-graft removal, IMA ligation and Y-graft replacement 19 months after endovascular aortic aneurysm repair. No structural damage was observed on the removed stent grafts.
