Primary Outcome Measures:
  • 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

  • Feasibility [ Time Frame: 30 Days ]
    Procedural Success with aortic/fenestrated and renal stent graft patency and absence of Type I/III endoleak or migration

Secondary Outcome Measures:
  • 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

  • Adverse Events [ Time Frame: Procedurally to 5 Years ]
    All adverse events, whether serious or non-serious

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

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

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

Enrollment: 15
