Recurrent aortoenteric fistula (AEF) is rare. This case study shows staged bridge solutions, including allograft in situ replacement and endovascular grafting, successfully treated recurrent AEF before definitive surgery.

Area of Science:

  • Vascular Surgery
  • Graft Management
  • Minimally Invasive Procedures

Background:

  • Recurrent aortoenteric fistula (AEF) is a rare and life-threatening complication following aortic graft surgery.
  • Current treatment options, such as graft excision and extra-anatomic bypass, carry high rates of mortality and morbidity.
  • Limited evidence exists for managing recurrent AEF, necessitating novel approaches.

Observation:

  • A patient with a recurrent aortoenteric fistula (AEF) was managed with a two-stage approach prior to definitive treatment.
  • The initial stage involved allograft in situ replacement of the affected aortic segment.
  • The second stage utilized endovascular grafting as a bridge solution.

Findings:

  • The staged approach involving allograft in situ replacement followed by endovascular grafting proved effective in managing the recurrent AEF.

  • The patient remained asymptomatic and active at 1, 3, and 6-month follow-ups.
  • This strategy potentially offers a lower morbidity alternative to immediate graft excision and extra-anatomic bypass.

    • Implications:

    • Staged bridge solutions may represent a viable treatment option for select patients with recurrent aortoenteric fistula.
    • This approach could potentially reduce the significant risks associated with traditional surgical interventions.
    • Further research and case studies are warranted to validate the long-term efficacy and safety of this management strategy.
