Extraabdominal Rupture of an Inflammatory Abdominal Aortic Aneurysm in a Patient With Aortodecubital Fistula: A Case Report.

Aortodecubital fistula is a pathologic communication between aorta and a decubitus ulcer. It is very rarely encountered vascular condition in abdominal aortic aneurysms (AAA), with difficult diagnostics and high mortality. Patients often present with systemic and local infection and are at risk for hemorrhage. We present a paraplegic patient with fistulous communication between an inflamed abdominal aortic aneurysm and a sacral decubitus ulcer, leading to intermittent bleeding episodes and finally to exsanguination. While extremely rare, this case emphasizes the need for early, accurate diagnosis and salvage intervention when possible.
