Secondary aorto-enteric fistula (AEF) is a serious, but rare, complication following surgery of the abdominal aorta. AEF occurs in 0.3–2%, but is associated with a hospital mortality between 25–90%. It is also associated with an important morbidity with a lower limb amputation rate of 9%, and a 15% risk for renewed graft infection.
Nine secondary AEF were surgically treated. The hospital mortality was high, 44% (4/9). Recurrent AEF was observed in 1 patient 2 years after the first operation. During follow-up 2 patients had mild infections which were resolved by antibiotic treatment.
Diagnostic modalities, and recent advancements in surgical treatment as well as preventive measures are discussed.
