Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The primary objective is to evaluate the safety and effectiveness of surgeon modified endografts for the treatment of pararenal and thoracoabdominal aortic pathology in patients who are not candidate for traditional open repair due to comorbid issues and their anatomy is not amenable to commercially available endografts.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Physician-modified endografts

For this clinical protocol, endografts which are commercially available will be modified in a sterile fashion on a back-table in the operating room.

Group Type EXPERIMENTAL

PMEG

Intervention Type DEVICE

All devices that will be modified in this study protocol are commercially available in the United States. The commercially available endografts will be used to construct a fenestrated/branched device for this intervention.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

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
