Aorto-enteric fistula is a serious complication to aortic surgery. Modern trends in diagnosis and therapy

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. (C) 2003 The International Society for Cardiovascular Surgery.
