| Aortic region | Preoperative mean (min–max) | Postoperative mean (min–max) | Change in AMA | P value |
| Thoracic | 1.20 (0.99–1.69) | 1.09 (0.85–1.47) | −0.11 | 0.41 |
| Suprarenal | 1.98 (1.12–3.6) | 1.36 (1.08–1.85) | −0.62 | 0.03 |
| Neck | 1.93 (0.96–3.54) | 1.21 (0.82–1.63) | −0.72 | 0.02 |
| Aneurysm body | 1.74 (0.6–3.24) | 1.05 (0.61–1.43) | −0.69 | 0.02 |
Mean AMA values across each aortic region, and change in AMA following EVAR.
AMA, aortic microcalcification activity; EVAR, endovascular aneurysm repair.
