About this trial

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.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Provision of signed and dated informed consent form

Male or female, aged ≥18 years

Expected survival beyond 1 year following successful aneurysm repair

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

Disqualifiers

Moderate-to-severe aortic neck calcification, thrombus, or tortuosity

Severe iliac stenosis, calcification, or tortuosity with no ability to perform a conduit

Proximal landing within zone 0 or 1

Inability to maintain at least one patent hypogastric artery

Trial design

Design model

Single group

Treatments tested in this trial

  • PMEG

    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.

Trial outcomes

Primary outcomes

1

Number of subjects with 30-day major adverse events from primary procedure

Major adverse events include: aortic-related mortality, major stroke, myocardial Infarction, permanent spinal cord ischemia, renal failure, bowel Ischemia (requiring laparotomy/bowel resection), respiratory failure (mechanical ventilation \>72 hours or requiring tracheostomy), lower extremity ischemia, blood loss ≥1,000cc

Time frame
Day 30
2

Number of subjects with treatment success

Treatment success is defined as a composite of: technical success, device integrity (freedom from stent fractures), freedom from aortic enlargement ≥5mm compared to preoperative CT imaging, freedom from aortic rupture, freedom from reintervention for type I or III endoleak or patency-related event, freedom from conversion to open aneurysm repair, freedom from aneurysm-related mortality.

Time frame
Month 12

Secondary outcomes

1

Number of subjects with mortality, major adverse events, spinal cord ischemia

Mortality includes all-cause mortality. Major adverse events include: aortic-related mortality, major stroke, myocardial Infarction, permanent spinal cord ischemia, renal failure, bowel Ischemia (requiring laparotomy/bowel resection), respiratory failure (mechanical ventilation \>72 hours or requiring tracheostomy), lower extremity ischemia, blood loss ≥1,000cc. Spinal cord ischemia data will include all incidence and degree of spinal cord ischemia.

Time frame
Day 30, Month 6, Month 12, Month 24, Month 36, Month 48, Month 60
2

Number of subjects with treatment success and freedom from secondary intervention

Treatment success is defined as a composite of: technical success, device integrity (freedom from stent fractures), freedom from aortic enlargement ≥5mm compared to preoperative CT imaging, freedom from aortic rupture, freedom from reintervention for type I or III endoleak or patency-related event, freedom from conversion to open aneurysm repair, freedom from aneurysm-related mortality. Freedom from secondary interventions includes interventions to treat malperfusion, rupture, aneurysm formation, aortic expansion, endoleak, device stenosis/occlusion, or access site complication.
