About this trial
This is an interventional treatment trial for Juxtarenal Aortic Aneurysm focused on measuring aneurysm, renal stent, juxtarenal, pararenal
Eligibility Criteria
Inclusion Criteria:
- Informed consent understood and signed and pt agrees to all follow-up visits;
- Abdominal aortic aneurysm with diameter ≥5cm or ≥4cm which has increased by 0.5cm or more in the past six months
- Adequate iliac/femoral access compatible with the required delivery systems
- Non-aneurysmal infrarenal aortic neck <15mm in length
- Most caudal renal artery to aortoiliac bifurcation length at least 70mm
- Proximal non-aneurysmal aortic neck below the SMA with: diameter 18 to 34 mm; length at least 15 mm; angle (clock face) <60° to the aneurysm sac;
- Angle <60° (clock face) between the SMA and celiac artery
- Renal arteries both distal to the SMA by 0-35mm, within 30mm of each other axially, with 4 to 8mm lumen diameter, and with clockface angle of 90° to 210° to each other
- Iliac anatomy suitable for commercial bifurcated stent graft;
- Minimum 3cm overlap achievable between fenestrated and bifurcated stent grafts
Exclusion Criteria:
