New treatment option for Abdominal Aortic Aneurysms (AAA)
Official title Endovascular Repair With Fenestrated TREO Stent-Graft System in AAA
ClinicalTrials.gov ID: NCT07026877
What this study is testing
- What it's testing
- The goal of this clinical trial is to learn if the Fenestrated TREO Stent-Graft System works to treat abdominal aneurysms in adults. An abdominal aneurysm is a bulge in the main blood vessel (the aorta) which carries blood from the heart, through the chest and abdomen.
A plain-language read of the study's public ClinicalTrials.gov listing. The study team confirms the details.

- Aneurysm with a history of growth \> 0.5 cm in 6 months and
- Minimum 0 mm of healthy aorta\ below the most inferior renal artery that the physician plans on preserving and no renal artery involvement (juxtarenal aneurysms) or

- Proximal landing zone:
- ≥20 mm length
- 20-32 mm diameter
- ≤60° angle relative to the axis of the suprarenal aorta
- ≤60° angle relative to the long axis of the aneurysm
- Distal (iliac) landing zone with:
- 8-13 mm inside diameter/ ≥10 mm length

- Pathology that requires fenestration a minimum 3 mm apart (edge to edge)
- Branch vessels (to be bridged to the fenestrated graft) with:
- 5-9 mm diameters
- ≥13 mm distal landing zone (or ≥15 mm if there is a gap between fenestration and target vessel)
- Adequate renal function to tolerate contrast-enhanced CTA
- Adequate vascular access compatible with required delivery systems
- Willingness to comply with the follow-up evaluation schedule documented in a signed informed consent prior to implant
What rules you out

- Implant procedure as planned does not allow for at least one patent hypogastric artery left intact, unless both are occluded on pre-op imaging.
- A branch vessel(s) that is dissected or has significant calcification, tortuosity, thrombus formation that would interfere with bridging stent delivery or sealing (as determined by treating physician)
