    Summary
    This summary is machine-generated.

    Inflammatory abdominal aortic aneurysms are rare but may be a variant of atherosclerotic aneurysms. Recognizing their features can help avoid surgical complications.

    Area of Science:

    • Vascular Surgery
    • Gastroenterology

    Background:

    • Inflammatory abdominal aortic aneurysms (IAAA) are infrequently reported.
    • There is ongoing debate regarding whether IAAAs are a distinct entity or a variant of atherosclerotic abdominal aortic aneurysms (AAA).

    Purpose of the Study:

    • To review operative reports of patients with IAAAs.
    • To determine the characteristics and outcomes of IAAAs.
    • To assess the relationship between IAAAs and atherosclerotic AAAs.

    Main Methods:

    • Retrospective review of operative reports from 24 patients diagnosed with IAAAs.
    • Analysis of aneurysm size, patient symptoms, diagnostic imaging findings, and surgical procedures.
    • Evaluation of intraoperative complications and patient outcomes.

    Main Results:

    • Of 24 patients, 21 had intact IAAAs (5-12 cm) and 3 had ruptured IAAAs (5-10 cm).
    • Nine patients with intact IAAAs experienced abdominal or back pain.
    • Excretory pyelography revealed obstruction in only 3 of 13 patients.
    • Surgical interventions included tube grafts (9), aortoiliac grafts (10), and aortofemoral grafts (5).
    • One duodenal injury and one left renal vein division occurred intraoperatively.

    Conclusions:

    • The study suggests that inflammatory abdominal aortic aneurysms are a variant of atherosclerotic abdominal aortic aneurysms.
    • Awareness of the pathological features of IAAAs can aid in preventing intraoperative complications.
