Fig 1 Computed tomography (CT) central luminal line (CLL) measurements illustrate the assessment of proximal migration after endovascular repair. Left, In this case (patient 9), the left proximal stent graft was 15.6 mm inferior to the superior mesenteric artery (SMA) on the 1-month CT. Right, At 1-year, the left proximal stent graft had migrated caudally by 7.1 mm and is resting 22.7 mm inferior to the SMA.

Fig 2 Computed tomography (CT) central luminal line (CLL) measurements illustrate the assessment of distal migration. Left, In this case (patient 3), the left distal stent graft was 20.2 mm superior to the common iliac artery bifurcation on the 1-month CT scan. Right, By 1-year, the left distal stent graft was located 19.2 mm superior to the common iliac artery bifurcation, with no evidence of migration.

Fig 3 Coronal maximum intensity projections demonstrate the migration of both stent grafts (patient 17) from the (left) 1-month post-endovascular aneurysm sealing (EVAS) computed tomography (CT) scan to (right) the 1-year post-EVAS CT scan. The coronal maximum intensity projections images were used as part of further scrutiny to visually verify (within the research team) the existence of migration.
