Representative pathological findings of aneurysm neck and renal organ tissue. A–B Thick neointima completely covers the aneurysm neck; endothelialization inside the device is mild and evenly distributed in the 28-day group. B shows a local magnification of the image in A. C–D The aneurysm was completely occluded 90 days after device placement. E–H Normal tissue organization found in the renal organ in 90-day (E–F) and 180-day (G–H) groups. F, H Higher magnification of E and G, respectively, shows that the morphology of the glomeruli and renal tubules is normal, and the cells are regularly arranged. A, C Hematoxylin and eosin (H&E)-staining images (0.62 ×). B, D H&E-staining images (5 ×). E, G H&E-staining images (2.5 ×). F, H H&E-staining images (10 ×)
