Aortic and iliac graft fistulae

Area of Science:

• Vascular Surgery
• Diagnostic Imaging

Background:

• Aortic and iliac graft fistulae are rare but serious complications following abdominal aortic reconstructive operations.
• Early and accurate diagnosis is essential for effective management and improved patient outcomes.

Purpose of the Study:

• To report the diagnostic experience with aortic and iliac graft fistulae.
• To highlight the key diagnostic modalities and clinical approaches.

Main Methods:

• Retrospective review of over 886 abdominal aortic reconstructive operations.
• Analysis of diagnostic methods used for patients with confirmed graft fistulae.
• Focus on radiographic studies, including angiography and barium intestinal studies.

Main Results:

• Sixteen cases of aortic and iliac graft fistulae were identified.
• Preoperative diagnosis was achieved in 12 patients, with 11 diagnosed via radiographic studies.
• Angiography and barium intestinal studies proved most effective in diagnosis.

Conclusions:

• A high index of suspicion is paramount for diagnosing graft fistulae.
• An aggressive and comprehensive radiographic approach is critical for successful preoperative identification.
