Abstract

Background and purpose

Endovascular aneurysm repair (EVAR) is the main treatment for patients with abdominal aortic aneurysms. This study examines the relationship between the migration of the distal landing zone and the length of the landing zone.

Materials and methods

The subjects of this study were 36 patients who underwent contrast-enhanced computed tomography 1 year after EVAR. We constructed curved multi-planar reconstruction imaging and measured the length of migration, the angle of the common iliac artery, and the diameter of the distal landing zone.

Results

The mean length of migration was 1.2 ± 1.7 mm. Fifty-four legs had a distal landing zone of over 15 mm and 18 legs had a distal landing zone of less than 15 mm. Four (7.4 %) of the 54 legs with a landing zone of over 15 mm and 3 (16.7 %) of the 18 legs with a landing zone of less than 15 mm had migration of over 3 mm. This difference was significant (P = 0.05).

Conclusion

The rate of migration on the distal landing zone 1 year after EVAR was reasonable when the length of the landing zone was about 15 mm. It is possible that significant migration can occur in patients with distal landing zones less than 10 mm in length.
