Prospective Aneurysm Trial: High Angle Aorfix™ Bifurcated Stent Graft

Not Applicable
Completed
Conditions
Abdominal Aortic Aneurysms
Interventions
Procedure: Open surgical repair
Device: Stent Graft
Registration Number
NCT00522535
Lead Sponsor
Lombard Medical
Brief Summary

Purpose of this study: The purpose of the study is to evaluate the safety and effectiveness of the Lombard Medical endovascular Aorfix™ AAA bifurcated stent graft in the treatment of abdominal aortic, aorto-iliac and common iliac aneurysms with anatomies including angled aorta, angled aneurysmal body, or both, between 0° and 90°.

Study hypothesis: The primary efficacy hypothesis is the proportion of grafts remaining free from endoleak, migration, and fracture at 12 months.

Efficacy: The 12 month, all cause mortality rate in the Aorfix™ group will be non-inferior to the 12 month, all cause mortality rate in the Open Control group.

Safety: The rates of early serious adverse events between 0 and 30 days post-operative in the Aorfix™ groups will be non-inferior to the early serious adverse event rates between 0 and 30 days post-operative in the Open Control group.

GroupInterventionDescription
Open Surgical RepairOpen surgical repairOpen surgical repair of abdominal aortic aneurysm. All patient enrollment and 2-year follow-ups completed.
Continued AccessStent GraftEndovascular treatment arm of 50 patients maximum having suitable anatomy for the Aorfix™ AAA Flexible Stent Graft System. This Arm will provide active sites with ongoing device access while FDA reviews the PMA. Patient recruitment completed; 5-year patient follow-ups continue.
Endovascular RepairStent GraftEndovascular treatment arm of 160 patients having suitable anatomy for the Aorfix™ AAA Flexible Stent Graft System. Use of stent grafts in aortic angles greater than 60° has not been approved for other devices available in the US. As a result, a minimum of 120 patients in this arm will have an aortic angle between 60° and 90°. Patient recruitment completed; 5-year follow-up evaluations continue.
