  Purpose

This study will compare two groups of subjects with complex abdominal aortic aneurysms. It will compare their clinical outcomes and quality of life measures. The group being treated in this study will have their aneurysms repaired by an endovascular approach using Zenith® Fenestrated AAA Endovascular Graft. This group will be compared to a group of 461 patients (historical cohort) whose complex aneurysms were treated by open surgical repair.

Primary Outcome Measures:
  • Number of Subjects Who Die [ Time Frame: 30 days ] [ Designated as safety issue: Yes ]
  • Number of Subjects Who Experience a Major Adverse Event [ Time Frame: 30 days ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Subject Scores on Short Form-36 (SF-36) Quality of Life Questionnaire [ Time Frame: baseline, 6 weeks, 6 months, 1 year, 2 years, 3 years, 4 years, 5 years. ] [ Designated as safety issue: No ]
    Subjects completed the SF-36 which consists of 8 sub-scales which are additionally summarized into 2 summary components (physical and mental). The subscales and the summary scales both range from 0 to 100, with (0 = worst imaginable, 100 = best imaginable).

  • Number of Subjects Who Achieve Treatment Success [ Time Frame: 12 months ] [ Designated as safety issue: No ]

    Treatment success is defined by a composite end-point, which includes all the following criteria described below:

    • Technical success, defined as successful delivery and deployment of the custom-made endovascular graft with preservation of those branch vessels intended to be preserved.
    • Freedom from type I or III endoleak.
    • Freedom from stent-graft migration.
    • Freedom from aneurysm enlargement >5mm
    • Freedom from aneurysm rupture or conversion to open repair.


Estimated Enrollment: 100
Study Start Date: August 2013
Estimated Study Completion Date: December 2018
Estimated Primary Completion Date: January 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Endovascular

Device: Custom-made Zenith® Fenestrated AAA Endovascular Graft. Instead of making a large incision in the abdomen,the physician makes two small incisions in the groin. Through these incision the devices are placed into the aorta.

Other names:

Endovascular stent Stent-graft

Device: Custom-made Zenith® Fenestrated AAA Endovascular Graft:
The graft will be inserted through arteries in the leg (called endovascular repair). Endovascular repair is a procedure that uses catheters that go inside your blood vessel to place a stent graft above and below the aneurysm. This procedure lines the aneurysm with a new lining (stent) so blood does not fill the artery any more.
Other Names:
  • Endovascular stent
  • Stent-graft

Criteria

General Inclusion Criteria

A patient may be included in the study if the patient has at least one of the following and is appropriate for treatment with a custom-made Zenith® Fenestrated AAA Endovascular Graft:

  • Aneurysm with a history of growth ≥ 0.5 cm per year.
  • Saccular aneurysms deemed at significant risk for rupture based upon physician interpretation.

General Exclusion Criteria

  • Less than 18 years of age
  • Unwilling to comply with the follow-up schedule
  • Inability or refusal to give informed consent by the patient or a legally authorized representative
  • Pregnant or breastfeeding
