Infolding of a fenestrated-branched stent graft is an infrequent complication due to excessive oversizing. We report the case of an 89-year-old man who underwent a four-vessel fenestrated-branched endovascular aortic repair for a pararenal aortic aneurysm. Computed tomography angiography revealed severe infolding across the mesenteric-renal vessels. The patient was treated by angioplasty and placement of Palmaz stent. Cone-beam computed tomography confirmed patent visceral vessels with resolution of the infolding. This case illustrates an uncommon complication that can be prevented by modifications in the stent design and by immediate assessment using intraoperative cone-beam computed tomography.
