Micro-CT sections of explanted aneurysms treated with 2 types of V-POD taken at 3 positions, as indicated in the schematic. Micro-CT sections of explanted aneurysms treated with 2 types of V-POD taken at 3 positions, as indicated in the schematic. Brighter dots are the nitinol struts of the stents, white arrows indicate the soft tissue, and dotted arrows indicate the holder. The PTFE patch is not visible because it has an attenuation similar to that of the soft tissue. The artery lumen is filled with air, and the intensity value is the same as that outside the sample. There are no cavities filled with air in the aneurysm dome, indicating total aneurysm occlusion. C.N. Ionita et al. AJNR Am J Neuroradiol 2011;32:1399-1407 ©2011 by American Society of Neuroradiology
