Abstract

Purpose

To evaluate the aneurysm neck angle changes and post-endovascular aneurysm repair (EVAR) complications.

Methods

We retrospectively analyzed 72 cases of elective EVAR for abdominal aortic aneurysm among 109 consecutive cases from December 2005 to April 2014. Patients were divided into angulated and non-angulated groups. The angulated group was defined as neck angulation ≥60°. Neck angle was evaluated pre- and post-EVAR during short- (within 1 month), mid- (3–6 months), and long-term (>1 year) follow-up. Aneurysm sac diameter change, aneurysm neck morphology other than angulation, endoleaks, and other post-procedural complications were also documented.

Results

A total of 34 patients were enrolled in the angulated group. There were no statistical differences in age, sex, follow-up duration, and aneurysm neck profile between the two groups (p > 0.05). Both groups showed statistically significant and consistent decreases in angulation during the follow-up period (p < 0.01). The angulated group revealed 22.45 % more straightening than the non-angulated group. Recoil of the Endurant device occurred in the angulated group. No statistically significant intergroup differences were observed in any endoleaks, complications, or re-intervention rates (p > 0.05). Pre-EVAR angle was the only predictor for post-procedural angle change (p < 0.001).

Conclusion

EVAR is applicable for patients with highly angulated aneurysm neck and provides consistent neck straightening over long-term follow-up. Recoil was evident in the angulated group using the Endurant device.
