Custom stent grafts offer new hope for High-Risk aneurysm patients
NCT ID NCT07224230
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is testing whether doctors can modify existing stent grafts to treat complex aortic aneurysms in patients who are too high-risk for open surgery and don't qualify for standard devices. The custom grafts are tailored to each patient's anatomy and placed using a minimally invasive procedure through leg arteries. The trial will follow 15 participants for up to 5 years to check safety and effectiveness.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Physician-modified endograft (a custom-fitted stent graft device)
- What this could lead to
- If successful, this approach could offer a minimally invasive treatment option for patients with complex aortic aneurysms who currently have no good alternatives.
- What could go wrong
- This is a very small early study with only 15 participants, so results may not apply to everyone. There are risks of serious complications like device failure, aneurysm rupture, or organ damage.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Patient is \> 18 years of age. * Patients who are male or non-pregnant female (females of childbearing potential must have a negative pregnancy test prior to enrollment into the study) * Patient is able and willing to sign an Institutional Review Board (IRB) approved Informed Consent Form * The subject has at least one of the following: 1. . An aortic or aortoiliac aneurysm with a maximum diameter of ≥ 5.5cm for males, ≥ 5.0cm for females 2. Aortic Aneurysm with a history of growth ≥ 0.5 cm in 6 mos. 3. Symptomatic aneurysm 4. Morphology such as saccular aneurysms 5. Aneurysms meeting any of the above criteria a-e above or below the previous endovascular and/or open aortic repairs. Previously placed aortic stent graft or open aortic grafts may serve as seal zones. * Cannot be treated with a currently available non-modified approved device. * Patient has patent iliac or femoral arteries that will allow endovascular access with the physician modified graft or is suitable for an iliac conduit. * Patient has a suitable non-aneurysmal proximal aortic neck length (seal zone) of ≥ 20mm. * 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. * Patient has suitable non-aneurysmal distal common iliac diameters between 7 and 20mm. * Chronic Dissection with aneurysmal degeneration that meets size criteria as described above for repair * Type 1A endoleak requiring extension above the previous repair into the pararenal or paravisceral portion of the aorta to achieve 2 cm of seal. Exclusion Criteria: * patient has a mycotic aneurysm * patient has a systemic or local infection that may increase the risk of graft infection. * Body habitus that would inhibit x-ray visualization of the aorta or exceeds the safe capacity of the equipment. * Subject has had a major surgical or interventional procedure unrelated to the treatment of the aneurysm planned \< 30 days of the endovascular repair. * Patient is currently participating in another investigational device or drug clinical trial. * Eligible for treatment with FDA-approved marketed device * Can enroll in a manufacturer-sponsored clinical study at our institution or is willing and eligible to participate in a study with a manufacturermade device at another institution. * Unwilling to comply with the follow-up schedule. * Inability or refusal to give informed consent by subject or legal representative. - The subject is pregnant or breastfeeding. * Known sensitivities or allergies to the materials of construction of the devices, including stainless steel, polyester, polypropylene, nickel, titanium, or gold. - Known hypersensitivity or contraindication to anticoagulation or contrast media that is not amenable to pretreatment * Uncorrectable coagulopathy * Unstable angina (defined as angina with a progressive increase in symptoms, new onset at rest or nocturnal angina) * Systemic or local infection that may increase the risk of endovascular graft infection. * History of connective tissue disorders (e.g., Marfan Syndrome, Ehlers's Danlos Syndrome) without landing zone created from graft via previous open repair. - Patient has active malignancy with life expectancy of less than 2 years. * Patient has a limited life expectancy of less than 2 years. * Patient has other medical, social, or psychological conditions that, in the opinion of the investigator, preclude them from receiving the pretreatment, required treatment, and post-treatment procedures and evaluations. * Anatomical exclusion criteria such as significant occlusive disease, tortuosity or calcification that would prevent endovascular access. * proximal seal site with a circumferential thrombus/atheroma * inability to maintain at least one hypogastric artery. * shaggy aorta * patient is not amenable to a temporary or permanent open surgical or endovascular conduit. * Thrombus or excessive calcification within the neck of the aneurysm
