Figure 4c. Typical CT angiographic appearance of AA: phase 3—follow-up (same patient as in Fig 2). Follow-up multi-detector row CT angiogram (a), MIP images (b, c), and MPR images (d, e) obtained 6 months after stent placement to assess patency show that the stent is correctly positioned, protruding a few millimeters into the aortic lumen. No signs of in-stent restenosis are visualized.
