    Endovascular approach to thrombosed limb of aortoiliac endoprosthetic stent graft following abdominal endovascular aneurysm repair
    (Elsevier, 2022-07-20) Willhite, Sydney R.; Warner, Adam C.; Hain, Julius S.; Nickerson, Margaret C.; Peterson, David A.; Cuddy, Duangnapa S.; Graduate Medical Education, School of Medicine
    The increasing use of endovascular aneurysm repair to treat abdominal aortic aneurysms has mandated solutions to the limitations of this operation, including the requirement for additional procedures. A 64-year-old man had presented with symptomatic thrombosis of the left iliac limb after endovascular aneurysm repair. We have reported the use of an innovative endovascular repair for our patient.

    Expanded Utility of Human Acellular Vessel in Hemodialysis Access Surgery and Arterial Aneurysm Repair
    (Springer Nature, 2023-10-01) Nickerson, Margaret C.; Thamba, Aish; Rao, Varun; Peterson, David B.; Peterson, David A.; Cuddy, Duangnapa S.; Surgery, School of Medicine
    Vascular access is essential for hemodialysis (HD) in patients with end-stage renal disease (ESRD). When the standard of care arteriovenous fistula (AVF) is limited, secondary to aneurysmal degeneration, trauma, and thrombus, interposition grafting is a reasonable reconstruction approach. As these grafts and comorbidities place ESRD patients at sustained risk of complications, reconstructions with regenerative medicine biologic conduits hold promise in improving safety and efficacy. Here, a biocompatible human acellular vessel (HAV) is our conduit of interest. With United States Food and Drug Administration use authorization under the Expanded Access Program, we report three cases of complex vascular access surgery with four aneurysm repairs using HAV. Patient selection focused on meeting unmet needs for those without adequate care alternatives, including active access and endoprosthetic stent graft infections, right heart failure due to high-output AVF, and arterial and access outflow aneurysms. In this high-risk expanded access population, operative technical success and interval success for patients given their inherent comorbidities, offer potential expanded utility of HAV in HD access surgery and arterial aneurysm repair.
