Who can take part
AI summary
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for adults with a juxtarenal abdominal aortic aneurysm (a bulge in the main belly artery near the kidney arteries). It can be planned, causing symptoms or ruptured, in people with limited or no other treatment options.
- Age
- Over 18 years.
- Sex
- Men and women who are not pregnant. Women who could become pregnant need a negative pregnancy test before joining.
- Disease stage
- The aneurysm must be over 5.5 cm (2.2 in) wide, or have grown 0.5 cm (0.2 in) in the last 6 months, or be more than 1.5 times the width of a nearby normal part of the aorta. The artery shape must allow the graft: neck length over 2 mm below the lowest kidney artery, neck width between 20 and 32mm, neck angle under 60º, and iliac artery length over 15 mm with width between 8 and 20 mm.
Main reasons for not taking part
- An infected aneurysm or an active infection in the body.
- Unstable angina (worsening chest pain), or another major procedure planned within 30 days of the repair.
- Connective tissue disease, such as Marfan's or Ehler's-Danlos syndrome.
- Allergy to blood thinners, contrast dye, stainless steel or gold.
- Expected to live less than 1 year, or able to join a company-sponsored device study at the site.
The registry criteria, word for word

Who can take part
- All patients must meet all of the following inclusion criteria to be eligible for enrollment into this study:
- Patient is > 18 years of age
- 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)
- Patient or Legally Authorized Representative has signed an Institutional Review Board (IRB) approved Informed Consent Form
- Patient has a juxtarenal abdominal aortic aneurysm that meets at least one of the following: Abdominal aortic aneurysm >5.5 cm in diameter, Aneurysm has increased in size by 0.5 cm in last 6 months, Maximum diameter of aneurysm exceeds 1.5 times the transverse dimension of an adjacent non-aneurysmal aortic segment
- Patient has appropriate iliac/femoral artery anatomy for access, with or without the use of a conduit, that will allow endovascular access with the physician modified endovascular graft
- Patient has a suitable non-aneurysmal proximal aortic neck length of > 2 mm inferior to the most distal renal artery ostium
- Patient has a suitable non-aneurysmal distal iliac artery length (seal zone) of >15 mm. The resultant repair should preserve patency in at least one hypogastric artery
- Patient has a suitable non-aneurysmal proximal aortic neck diameter between 20 and 32mm, averaged across the diameters at the Celiac, SMA, at the lowest patent renal artery and at the midpoint of the renal arteries
- Patient has suitable non-aneurysmal distal common iliac diameters between 8 and 20 mm
- Patient has juxtarenal aortic neck angulation < 60º
- Patient must be willing to comply with all required follow-up exams
Who cannot take part
- Patient has a major surgical or interventional procedure planned within +/- 30 days of the AAA repair
- Patient is currently participating in another investigational device or drug clinical trial
- 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
- Patient has a mycotic aneurysm or has an active systemic infection
- 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)
- Patient has history of connective tissue disease (e.g., Marfan's or Ehler's-Danlos syndrome)
- Patient has a known hypersensitivity or contraindication to anticoagulation or contrast media that is not amenable to pre-treatment
- Patient has a known allergy or intolerance stainless steel or gold
- Patients that meet ANY of the following are not eligible for enrollment into the study:
- Patient has a body habitus that would inhibit X-ray visualization of the aorta
- Patient has a limited life expectancy of less than 1 year
- Subject is eligible for enrollment in a manufacturer-sponsored IDE at the investigational site

About the trial
What the trial wants to find out
The primary objectives of this study are to determine whether physician modified endovascular grafts (PMEG) and specified company manufactured investigational devices are a safe and effective method of treating patients with elective, symptomatic or ruptured juxtarenal aortic aneurysms in those patients considered to have limited or no other options for treatment. Secondary objectives include the validation of a patient-specific, 3-D printed aortic template as a surgical planning tool for fenestrated endografting.
