Initial experience with polymer endovascular aneurysm repair using the Alto stent graft

Abstract

The Alto Abdominal Stent Graft System (Endologix Inc, Irvine, Calif) is the next-generation Ovation system for polymer endovascular aneurysm repair. The most significant design change relocates the sealing ring closer to the top of the fabric, but a number of additional design changes were made. This report describes the first seven patients treated with the Alto stent graft at a single center (Auckland Hospital, Auckland, New Zealand) from August 2016 to February 2017. There was 100% procedural technical success. At 12-month follow-up, no type I or type III endoleak, stent graft migration, abdominal aortic aneurysm rupture, abdominal aortic aneurysm-related mortality, or secondary intervention was reported.
