Endovascular Juxtarenal Aortic Aneurysm Repair Using the ALTO Abdominal Stent Graft System: The First Case Series

Abstract

The ALTO abdominal stent graft system (Endologix Inc., Irvine, CA, USA) is a latest-generation polymer-based device used to treat patients with abdominal aortic aneurysms. The present study describes the first case series of patients with abdominal aortic aneurysms, including two patients with juxtarenal aneurysms, treated using the ALTO stent graft system. Six males were treated using the ALTO device at a single public center. All procedures were uneventful, and the dosimetric results recorded in terms of kerma-area product and fluoroscopy time were similar to those reported in previous studies. At the 1-month follow-up, computed tomography angiography showed no evidence of endoleak, device migration, thrombosis, or structural graft failure. This clinical series demonstrates that the use of the ALTO stent graft system is associated with promising patient outcomes. Lifelong postoperative imaging surveillance may highlight possible late failures and suggest potential graft improvements.

“…An alternative approach for treating this patient would be using a unibody AFX2 system, which has been reported as suitable for NAB patients [ 4 ]. Nevertheless, this was not feasible because the neck length was only 11 mm, which is adequate for the ALTO but not the AFX2 system [ 5 ]. Written patient consent was obtained for this report.…”
