Inflammatory abdominal aortic aneurysm (IAAA) is a distinct condition with specific clinical and histological features. This review highlights key characteristics differentiating IAAA from atherosclerotic abdominal aortic aneurysms.

Area of Science:

  • Vascular Surgery
  • Pathology
  • Immunology

Context:

  • Inflammatory abdominal aortic aneurysm (IAAA) presents unique clinical and pathological findings.
  • Distinguishing IAAA from atherosclerotic AAA is crucial for diagnosis and management.
  • The pathogenesis of IAAA remains incompletely understood.

Purpose:

  • To describe the clinical and histological features of IAAA.
  • To compare and contrast IAAA with atherosclerotic abdominal aortic aneurysm (AAA).
  • To review existing literature and present findings from six IAAA cases.

Summary:

  • IAAA is characterized by specific symptoms (e.g., back pain, elevated ESR), lymphoplasmacytic infiltration, and significant periaortic fibrosis.
  • Histological hallmarks include marked lamellar fibrosis replacing aortic wall layers, lymphocytic infiltration (primarily B cells), and endarteritis obliterans.

  • IAAA shares some features with atherosclerotic AAA but possesses distinct pathological characteristics.

    • Impact:

    • Provides a clearer understanding of IAAA as a distinct entity.
    • Aids in differentiating IAAA from atherosclerotic AAA, potentially improving diagnostic accuracy.
    • Contributes to the ongoing research into the pathogenesis of aortic aneurysms.
