Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 18 and older with specific anatomical conditions that prevent the use of standard endografts.
✕Probably not a fit
Patients with severe aortic neck calcification, tortuosity, or those who cannot achieve adequate arterial access may not benefit from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This study evaluates the safety and effectiveness of surgeon-modified endografts for patients with pararenal and thoracoabdominal aortic aneurysms who cannot undergo traditional open repair due to anatomical challenges or comorbidities. The approach involves customizing endografts to accommodate specific anatomical requirements, particularly when standard FDA-approved options are unsuitable. The study aims to provide a viable treatment alternative for patients with complex aortic pathology.
Why it matters
Potential benefit: If successful, this approach could offer a less invasive treatment option for patients with complex aortic aneurysms, potentially improving survival and quality of life.
How similar studies have gone: While this approach is innovative, similar studies have shown promise in using modified endografts for complex aortic conditions.

Show full inclusion / exclusion criteria
Inclusion Criteria: 1. Provision of signed and dated informed consent form 2. Male or female, aged ≥18 years 3. Expected survival beyond 1 year following successful aneurysm repair 4. Anatomy that would require coverage of the celiac artery, superior mesenteric artery (SMA), and/or renal arteries if conventional, FDA-approved endograft were implanted to obtain adequate sealing zone length 5. Aneurysm of the thoracoabdominal or pararenal aorta with or without chronic dissection 6. Adequate proximal zone of fixation 7. Adequate distal zone of fixation 8. No more than 5 non-aneurysmal visceral (celiac, SMA, or renal) arteries with diameters between 4-12mm 9. Adequate arterial access for delivery system; use of iliac conduit is permitted as necessary Exclusion Criteria: 1. Moderate-to-severe aortic neck calcification, thrombus, or tortuosity 2. Severe iliac stenosis, calcification, or tortuosity with no ability to perform a conduit 3. Proximal landing within zone 0 or 1 4. Inability to maintain at least one patent hypogastric artery 5. Freely ruptured aneurysm with hemodynamic instability 6. Non-ambulatory status 7. Severe CHF 8. Baseline eGFR \< 30ml/min, unless currently on or to be initiating dialysis 9. Unstable angina 10. Stroke or MI within 3 months of planned treatment date 11. Active systemic infection and/or mycotic aneurysm 12. Uncorrectable coagulopathy or other bleeding diathesis 13. Known allergy to device material or contrast material that cannot be adequately pre-medicated 14. Body habitus that would preclude adequate fluoroscopic visualization of aorta 15. Pregnancy or lactation (confirmed per standard of care surgical practice) 16. Major, unrelated surgical procedure planned ≤30 days from endovascular repair 17. Patient is ≤30 days beyond primary endpoint for another investigative clinical drug/device trial 18. Social or psychological issues that would interfere with ability to comply with all study procedures for the duration of the study 19. Can be treated in accordance with the instructions for use with a legally marketed endovascular device, including a manufacturer-fabricated custom device 20. Can enroll in a manufacturer-sponsored clinical study at our institution or is willing and eligible to participate in a study with a manufacturer-made device at another institution
