Summary

Endograft disintegration in abdominal aortic aneurysm repair can mimic endoleaks. This case highlights the importance of accurate diagnosis to prevent misdirected interventions and ensure proper treatment of aortic aneurysm complications.

Area of Science:

  • Vascular Surgery
  • Endovascular Aneurysm Repair (EVAR)
  • Aortic Aneurysm Management

Background:

  • Endovascular aneurysm repair (EVAR) is a common treatment for abdominal aortic aneurysms (AAAs).
  • Post-EVAR endoleaks are a known complication requiring careful monitoring and management.
  • Accurate differentiation between endoleak types and graft failure is crucial for successful outcomes.

Observation:

  • An 86-year-old male patient presented with a persistent endoleak after EVAR for AAA.
  • Multiple embolization attempts for the presumed type II endoleak were unsuccessful.
  • Aneurysm sac enlargement persisted despite interventions, prompting surgical exploration.

Findings:

  • Surgical findings revealed endograft disintegration with small holes in the graft fabric as the source of the 'endoleak'.

  • The degenerated endograft was successfully removed and replaced with a woven aortobi-iliac graft.
  • The initial diagnosis of a type II endoleak was incorrect, stemming from graft failure.

    • Implications:

    • Chronic endograft failure can present insidiously, mimicking other complications like endoleaks.
    • Diagnostic challenges in EVAR require thorough investigation to identify the true source of leaks or sac expansion.
    • Prompt and accurate diagnosis of graft failure is essential to prevent further aneurysm growth and potential rupture.
