Brief Summary:

EVAR continues to evolve as a treatment option for AAA. New devices which are specifically designed to perform adequately across the spectrum of potential anatomic presentations for infrarenal EVAR are needed. The Department of Vascular Surgery at Catharina Hospital Eindhoven, The Netherlands initiates the EXCeL Registry.

This study will assess the safety and effectiveness of the GORE® EXCLUDER® Conformable AAA Endoprosthesis (CEXC Device) in patients who meet the IFU anatomic criteria (≥15mm proximal neck length and ≤90˚ proximal neck angulation; and ≥10mm proximal neck length and ≤60˚ proximal neck angulation) and in patients with challenging anatomic presentation that may present outside the IFU anatomic criteria. Successful outcomes from this study will provide evidence to support the CEXC Device as an option for expanding EVAR to a broader patient population with more challenging anatomic presentations.

Group/Cohort Intervention/treatment
Patients with AAA
Patients with AAA are eligible for participation and study screening. They will receive, once included, an endovascular repair of the AAA
Procedure: endovascular repair of the AAA
The Investigator will ensure that investigational devices are used only in subjects properly enrolled in the clinical study in accordance with the protocol. Subjects will undergo endovascular repair of their AAA. Procedural details may vary between sites, but will follow standard hospital protocol for EVAR and patient care management.

Primary Outcome Measures :
  1. Primary safety success defined by the absence of major adverse events [ Time Frame: up to 30 days after index procedure ]
    These major adverse events are defined as all-cause mortality, stroke, mycardial infarction, bowel ischemia, paraplegia, respiratory failure, renal failure and thromboembolic events (including limb occlusion and distal embolic events).

  2. Technical treatment success [ Time Frame: At the primary procedure ]
    Proportion of subjects who experience successful, delivery and deployment of all required EXCC Device components annd successful removal of EXCC device delivery catheter(s)

  3. Clinical effectiveness success [ Time Frame: From the day after the initial procedure up to 3 years after the initial procedure (which is the end of the follow up period for this registry ]
    Effectiveness defined as absence of type I endoleak at each visit, Type III endoleak at the 12 month visit, migration (10 mm or more) between the one month and the 12 month visit, AAA enlargement >5 mm with or without intervention between the one month and the 12 month visit, AAA rupture through the 12 month visit, conversion to open repair through the 12 month visit, limb occlusion

Secondary Outcome Measures :
  1. Incidence of treatment-emerged adverse events (safety) [ Time Frame: From hospital admission before index procedure up to study completion after the 3 years follow up ]
    30 day major adverse events, individual elements of the primary safety and effectiveness endpoints, secondary procedures, type II endoleak, type IV endoleak, index procedure blood loss, index procedure time, length of hospital stay
