This is a Prospective, Open-label, Multicenter, and Non-randomized Clinical Study. The main purpose of this study is to establish the efficacy and safety of a medical device system, SETA LATECBA Stent Graft, intended for the treatment of EVAR of pararenal AAA (patients with complex anatomy, not eligible for other surgical procedure).Other objective is to evaluate the technical performance of the device SETA LATECBA Stent Graft.
This is a Prospective, Open-label, Multicenter, and Non-randomized Clinical Study to determine the Safety and Efficacy of the SETA LATECBA Stent Graft for endovascular repair therapy (EVAR) in Subjects with Abdominal Aortic Aneurysm (AAA)..The main purpose of this study is to establish the efficacy and safety of a medical device system, SETA LATECBA Stent Graft, intended for the treatment of Endovascular Aneurysm Repair (EVAR) of pararenal AAA (patients with complex anatomy, not eligible for other surgical procedure). Secondary objective(s): The secondary objective is to evaluate the technical performance of the device SETA. LATECBA Stent Graft which includes: access to the implantation site, visualization, deployment of the stent- graft, sizing compatibility, withdrawal of the delivery system, and compatibility with ancillary equipment.

ABK model is a bifurcated polyester graft partially corrugated which is sutured at the proximal end (renal) to a balloon expandable 316 L stainless steel stent. The proximal half part of the stent is uncovered by polyester graft providing the anchoring to the healthy aorta wall when the device is implanted, as well as the perfusion of the renal arteries. The remaining half part is covered by polyester graft providing sealing of the aneurysm when it is expanded upon on the graft fabric and aneurysm neck. The distal end of each branch has the anchorage site for sealing after the connection with the iliac extensions RIK. The diameter of the anchorage site varies with the different ABK codes. The end of one branch is cone-shaped after the anchoring diameter with the purpose of promoting insertion of iliac extension RIK. The connection to iliac arteries is achieved by completing the aortic trunk ABK with 2 iliac extensions RIK.

RECRUITINGEFFICACY: Number of participants with Endoleak Type I (measured by Angio CT Scan)
Type I endoleaks is diagnosed when there is a gap between the stent graft and the vessel wall. Usually is a result of the failure of the stent graft to achieve a circumferential seal of the aneurism. It produces systemic pressurization of the aneurysm sac and increases the risk of sac rupture.
