Aortoduodenal fistula

K J Hardy, B F Buxton, K J Millar

    The Medical Journal of Australia
    |May 8, 1976
    PubMed
    Summary

    Aortoduodenal fistulas, often linked to aortic aneurysms or surgical repairs, present with gastrointestinal bleeding. Early diagnosis and surgical intervention are crucial for managing this rare but serious condition.

    Area of Science:

    • Vascular Surgery
    • Gastroenterology

    Background:

    • Aortoduodenal fistula is a rare but life-threatening condition.
    • It can be primary, associated with aortic aneurysms, or secondary, related to aortic surgery.

    Observation:

    • Primary fistulas typically present with gastrointestinal bleeding (hematemesis or melena), abdominal pain, and a pulsatile mass.
    • Secondary fistulas manifest similarly but are linked to a history of aortic resection and anastomotic leaks.

    Findings:

    • Diagnosis involves identifying the connection between the aorta and duodenum, often during laparotomy.
    • Initial hemorrhage may not be fatal, allowing a critical window for surgical planning.

    Implications:

    • Treatment involves closing the duodenal defect and resecting any associated aneurysm.
    • Reconstruction techniques include aortic grafting or extra-anatomical bypass, depending on contamination levels.
