Brief Summary
The aim of this randomized study is to compare the safety and performance of EndoVascular Aneurysm Repair with ESAR using Endurant + Heli-FX™ EndoAnchor™ system and FEVAR using customizable grafts from Cook (Zenith Fenestrated Graft) and Terumo (Fenestrated Anaconda Graft) for the treatment of aortic aneurysms with short aortic neck (4 to 15mm).

Outcome Measures
Primary Outcomes (2)
Effectiveness Endpoint - Technical Success
Composite of technical success at index procedure, and freedom from type IA or type III endoleak, freedom from aneurysm related mortality (ARM), and freedom from secondary reinterventions through 12 months post index procedure.
through 12 months post-procedure
Safety Endpoint - Freedom from Major Adverse Events
Freedom from MAE through 30 days post index procedure. MAE defined as: All-Cause-Mortality, Bowel Ischemia, Myocardial Infraction, Procedural Blood Loss \> 1000cc, Access related complications, permanent paraplegia and paraparesis at 30 days, disabling stroke, respiratory failure, or renal complications
through 30 days post-procedure
Secondary Outcomes (15)

Eligibility Criteria
You may qualify if:
- Subject is \>18 years old
- Subject is scheduled for primary treatment of the abdominal aortic aneurysm with a non-aneurysmal infrarenal aortic sealing zone proximal to the aneurysm that is sufficiently healthy for a proximal neck length that is at least 4mm and not more than15 mm and has a circumferential minimum sealing zone length of 8 mm
- Subject is not a candidate for safe, effective and durable standard EVAR due to challenging anatomical criteria as confirmed by the Core Lab screening
- Subject is able and willing to comply with the protocol and to adhere to the follow-up requirements.
- Subject has provided written informed consent
- Subject meets the other anatomical requirements according to the locally applicable Endurant II/IIs stent graft system, Heli-FX EndoAnchor system, Terumo Fenestrated Anaconda (available in EU only) and/or Cook Zenith Fenestrated Graft Instructions for Use
- Proximal neck length of the aorta within 4-15mm and a minimum circumferential sealing zone of 8mm
- Aortic neck diameter from 19 to 31mm
- Infrarenal neck angulation ≤45°
You may not qualify if:
- Subject is participating in a concurrent study which may confound study results
- Subject has a life expectancy \<2 year
- Subject is female of childbearing potential in whom pregnancy cannot be excluded
- Subject with eGFR \<30 mL/min/m2 (KDOQI classification - exclude class IV and above) and or on dialysis
- Subject with a MI or CVA within 3 months prior to index procedure
- Subject with known Connective Tissue Disease
- Subject has a known hypersensitivity or contraindication to anticoagulants, antiplatelets, or contrast media, which is not amenable to post-treatment
- Subject who has undergone prior endovascular or open surgical treatment for abdominal aortic aneurysm
- Subject requires emergent aneurysm treatment, for example, trauma or rupture
- Subject has a known hypersensitivity or allergies to study device implant material
- Subject has an aneurysm that is:
- Suprarenal, pararenal, or thoracoabdominal
- Mycotic
- Inflammatory
- Pseudoaneurysm
