Size of the Proximal Neck in AAAs Treated with Balloon-Expandable Stent-Grafts: CTA Findings in Mid- to Long-term Follow-up

Purpose: To determine the evolution of the proximal aortic neck diameter in mid- to long-term follow-up after endovascular aneurysm repair of abdominal aortic aneurysm (AAA) with a balloon-expandable stent-graft. Methods: Thirty patients (27 men; average age 71 years, range 56–87) with infrarenal AA...

Description
Summary:Purpose: To determine the evolution of the proximal aortic neck diameter in mid- to long-term follow-up after endovascular aneurysm repair of abdominal aortic aneurysm (AAA) with a balloon-expandable stent-graft. Methods: Thirty patients (27 men; average age 71 years, range 56–87) with infrarenal AAAs were treated with the SETA-Latecba balloon-expandable stent-graft (6 aortomonoiliac and 24 bifurcated configurations). Follow-up ranged from 4 to 8 years (mean 73.4 months). Computed tomography was done systematically before the procedure, after implantation (1–3 months), at 1 year, and annually thereafter. The last follow-up scan was utilized to measure the proximal neck for purposes of comparison with baseline and the initial post-implant scans. Results: Five patients died during follow-up of causes unrelated to the procedure. No endoleaks or graft migrations were observed. The pre-deployment proximal neck diameter (a) averaged 23.4 mm (range 18–32), the diameter after deployment of the stent-graft (b) averaged 24.9 mm (range 18–34), and the most recent follow-up proximal neck measurement (c) averaged 23.8 mm (range 18–31). Comparing the last follow-up to the post-implant measurements (c–b), the neck diameter decreased in 15 (50%) patients [7 with short necks (i.e.,
