Arm Intervention/treatment
Experimental: Ventana Fenestrated Stent Graft System Device: Ventana Fenestrated Stent Graft System

The Ventana Fenestrated Stent Graft System consists of the following:

bifurcated stent graft, Ventana fenestrated proximal extension stent graft, and Xpand renal stent grafts

Primary Outcome Measures :
  1. Safety [ Time Frame: 30 Days ]
    Major Adverse Events = all cause death; bowel ischemia; myocardial infarction; paraplegia; renal failure; respiratory complications of stroke; blood loss >1000cc

  2. Effectiveness [ Time Frame: 1 Year ]
    Treatment Success=Procedural technical success and absence of aneurysm rupture, conversion to open repair, Type I endoleak after 30 days, Type III endoleak, clinically significant migration; aneurysm enlargement; or secondary intervention for resolution of endoleak, limb occlusion, migration, aneurysm sac expansion and/or a device defect

Secondary Outcome Measures :
  1. Safety [ Time Frame: >30 Days to 5 Years ]
    Major Adverse Events = all cause death; bowel ischemia; myocardial infarction; paraplegia; renal failure; respiratory complications of stroke; blood loss >1000cc

  2. Distal Blood Flow [ Time Frame: Discharge to 5 Years ]
    Ankle-brachial index measurements

  3. Renal Dysfunction [ Time Frame: Discharge to 5 Years ]
    eGFR reduction >30% from baseline

  4. Device Performance [ Time Frame: 30 Days to 5 Years ]
    Aortic, fenestrated, and renal stent graft integrity and patency; migration; endoleak; and aneurysm sac morphology

  5. Clinical Utility Outcomes [ Time Frame: At the time of the procedure ]
    Clinical Utility Outcomes consists of: anesthesia time; fluoroscopy time; contrast volume; estimated blood loss; % requiring transfusion; procedure time

  6. Time in ICU [ Time Frame: In-Hospital ]
    Number of hours spent in the intensive care unit (ICU)

  7. Time to Hospital Discharge [ Time Frame: Hospital Discharge (Post-Procedure) ]
    Number of days from the index procedure to discharge from the hospital.
