78-year-old man with stents migration. a Volume rendering reconstruction and b sagittal oblique CT images show a thoracoabdominal aneurysm treated with a f/b EVAR and three stent-grafts placement in aortic branches: celiac artery (CA), superior mesenteric artery (SMA) and right renal artery (RRA); the last one appears occluded. c Volume rendering and (d) sagittal oblique CT images after 3 years show distal migration of all three stent-grafts. In both examinations, there is contrast agent inside the aneurismal sac (*), likely a type IIIb endoleak due to imperfect junction of the branches with the main device body
