Intervention Details:
  • Device: Endovascular Aortic Aneurysm Repair (Endologix Fenestrated Stent Graft System)
    Endovascular repair of juxtarenal or pararenal aortic aneurysm using the Endologix Fenestrated Stent Graft System
    Other Names:
    • Ventana
    • Xpand

Primary Outcome Measures :
  1. Primary Safety Endpoint [ Time Frame: 30 days ]

    Major adverse events defined as:

    • All-cause death
    • Bowel ischemia
    • Myocardial infarction
    • Paraplegia
    • Renal failure
    • Respiratory failure
    • Stroke
    • Blood loss >=1,000cc

Secondary Outcome Measures :
  1. Feasibility/effectiveness [ Time Frame: 30 Days ]
    Successful device delivery and deployment with patency of the renal and aortic endografts without Type I/III endoleak.

  2. Procedural/in-hospital evaluations [ Time Frame: Procedurally and to hospital discharge ]
    Anesthesia time; fluoroscopy time; contrast volume; estimated blood loss; % requiring transfusion; procedure time; ICU time; time to hospital discharge

  3. Mortality [ Time Frame: Procedurally and to 5 Years ]
    All-cause and aneurysm-related

  4. Major Adverse Events [ Time Frame: >30 Days to 5 Years ]
    All-cause mortality, bowel ischemia, myocardial infarction, paraplegia, renal failure, respiratory failure, stroke, blood loss >1,000cc

  5. Adverse Events [ Time Frame: Procedurally and to 5 Years ]
    All serious and non-serious adverse events

  6. Renal Dysfunction [ Time Frame: 30 Days, 6 Months and Years 1 to 5 ]
    Reduction in estimated glomerular filtration rate (eGFR) >30% from the preoperative value

  7. Aneurysm Rupture [ Time Frame: Procedurally and to 5 Years ]
    Internal bleeding or leaking of blood from the aneurysm subsequent to the index procedure

  8. Conversion to Open Repair [ Time Frame: Procedurally and to 5 Years ]
    Open surgical repair of the aortic aneurysm due to unsuccessful delivery or deployment of the stent graft, due to complications or other clinical situations that precluded successful endovascular treatment, or at any time following initial successful endovascular treatment for any reason

  9. Distal Blood Flow [ Time Frame: Pre-discharge, 30 Days, 6 Months, and Years 1 to 5 ]
    Ankle-brachial index measurements and changes over time

  10. Renal Stent Graft Patency and Integrity [ Time Frame: 30 Days, 6 Months, and Years 1 to 5 ]
    Patent luminal flow; absence of kinking, stenosis, occlusion, stent fracture, graft failure, or renal infarct >30%

  11. Stent Graft Patency and Integrity [ Time Frame: 30 Days, 6 Months, and Years 1 to 5 ]
    Bifurcated and fenestrated stent graft patent luminal flow; absence of stent fracture or graft fatigue/failure

  12. Endograft Performance [ Time Frame: 30 Days, 6 Months, and Years 1 to 5 ]
    Change in aneurysm sac diameter from the first post-procedural measurement; incidence of endoleak; incidence of device migration; incidence of limb occlusion

  13. Secondary Procedures [ Time Frame: 30 Days, 6 Months, and Years 1 to 5 ]
    Non-diagnostic intervention after the index procedure intended to correct or repair an endoleak (device-related: Type I (proximal or distal), Type III, Type IV; non-device related: Type II), device migration, or other device defect.
