The purpose of this study is to determine the long-term performance of the TREO Abdominal Stent-Graft as a treatment for patients with Infrarenal Abdominal Aortic Aneurysms or Aorto-iliac Aneurysms.


This is a prospective, multi-center, non-randomized, single-arm, post-market, non-interventional study of treatment with the TREO Abdominal Stent-Graft in subjects with Infrarenal Abdominal Aortic Aneurysms or Aorto-iliac Aneurysms. The study will include a minimum of 300 subjects treated with the TREO Abdominal Stent-Graft at up to 55 investigational sites in the US.

The primary objective is the collection of real world safety and effectiveness outcomes of the TREO Abdominal Stent-Graft System in an all-comers population eligible for the endovascular treatment of AAA in routine clinical practice, with emphasis on subjects that experience a device stent-strut or barb fracture.
