Physician-Modified Endovascular Grafts for Juxtarenal Aortic Aneurysms
Endovascular Aneurysm Repair with Physician Modified Endograft
Treatment Study
Summary
Study start date: August 1, 2025
Actual date on which the first participant was enrolled.This study focuses on treating juxtarenal aortic aneurysms, which are dangerous bulges in the aorta near the kidneys. The goal is to test a special device called a physician-modified endovascular graft (PMEG) to see if it is safe and effective for patients with these aneurysms. This device is not yet approved by the FDA, making it experimental. The PMEG acts as a tunnel for blood to flow through the aorta without increasing pressure on the aneurysm, which can prevent it from getting worse. The study targets patients with elective, symptomatic, or ruptured aneurysms, aiming to provide a new treatment option that could reduce the risks associated with this condition. Participants in this study will receive the PMEG device, which is inserted into the body through a small incision. The device is tailored with holes to ensure blood can still reach the kidneys and other vital organs without being blocked. Smaller grafts are used to connect these organs to the main graft, maintaining normal blood flow. The study will evaluate the device’s performance in ensuring safe blood flow and reducing aneurysm pressure. While the study seeks to prove the potential benefits of the device, as it is investigational, there may be unknown risks involved.

Inclusion Criteria: 1. Patient is ≥ 18 years of age 2. Patients who are male or non-pregnant female (females of child bearing potential must have a negative pregnancy test prior to enrollment into the study) 3. Patient or Legally Authorized Representative has signed an Institutional Review Board (IRB) approved Informed Consent Form 4. Patient has a juxtarenal abdominal aortic aneurysm that meets at least one of the following: 1. An aneurysm with a maximum diameter of ≥ 5.5 cm for male (≥ 5.0 cm for female) or 2 times the normal diameter just proximal to the aneurysm using orthogonal (i.e., perpendicular to the centerline) measurements 2. Aneurysm with a history of growth \> 0.5 cm in 6 months 3. Saccular aneurysm deemed at significant risk for rupture 4. Symptomatic aneurysm 5. Ruptured aneurysm 5. Patient has patent iliac or femoral arteries, with or without the use of conduit, that will allow endovascular access with the physician modified endovascular graft. 6. Patient has a suitable non-aneurysmal proximal aortic neck of ≥ 2 mm inferior to the most distal renal artery ostium. 7. Patient has a suitable non-aneurysmal distal iliac artery length (seal zone) of ≥ 15mm. The resultant repair should preserve patency in at least one hypogastric artery. 8. Patient has a suitable non-aneurysmal proximal aortic neck diameter between 20 and 32 mm, averaged across the diameters at the Celiac, SMA, at the lowest patent renal artery and at the midpoint of the renal arteries. 9. Patient has suitable non-aneurysmal distal common iliac diameters between 8 and 20 mm. 10. Patient has juxtarenal aortic neck angulation ≤ 60° 11. Target branch vessel diameter ≥ 5 mm. 12. Patient must be willing to comply with all required follow-up exams. Exclusion Criteria: 1. Patient has a mycotic aneurysm or has an active systemic or local infection that may increase the risk of endovascular infection 2. Patient has unstable angina (defined as angina with a progressive increase in symptoms, new onset at rest or nocturnal angina, or onset of prolonged angina) 3. Patient has a major surgical or interventional procedure, not related to the endovascular repair, planned within +/- 30 days of the AAA repair. 4. Patient has history of an aortopathic connective tissue disease (e.g. Marfan's or Ehler's-Danlos syndrome). 5. Patient has a known hypersensitivity or contraindication to anticoagulation or contrast media that is not amenable to pre-treatment. 6. Patient has known allergy or intolerance to stainless steel, nitinol or gold (gold-coated tungsten). 7. Patient has a body habitus that would inhibit X-ray visualization of the aorta 8. Patient has a limited life expectancy of less than 1 year 9. Patient is currently participating in another investigational device or drug clinical trial 10. Patient has other medical, social or psychological conditions that, in the opinion of the investigator, preclude them from receiving the pre-treatment, required treatment, and post-treatment procedures and evaluations. 11. Thrombus or excessive calcification within the neck of the aneurysm 12. Branch vessel stenosis ≥ 80% 13. Patient treatable on label with FDA approved EVAR or FEVAR device and can wait for device availability. 14. Subject is willing and eligible to enroll in a manufacturer-sponsored study at the investigational site, or the subject is willing and eligible to participate in a study with a manufacturer-made device at another institution.
