Bleeding caused by an aortoenteric fistula may be confusing, and must be differentiated, because immediate operation is mandatory.¹ Aortoenteric fistulization, first reported by Salmon² in 1843, frequently results from rupture of an abdominal aortic aneurysm into the bowel.

The incidence of this complication is higher today, consequent to frequent vascular surgical and aortic reconstructive procedures, and has been reported in up to 5% of cases.³ In 1963, Humphries et al³ reported 70 cases of aortoenteric fistula after aortic surgery, including 26 cases of their own, noting that preventive measures had reduced, but not abolished, this complication.

Although aortoenteric fistula following abdominal aortic aneurysm or aortoiliac reconstructive surgery has been reported by many investigators,^4-7 a vascular enteric fistula after a renal artery bypass graft has been reported only once.^8.9 Our . . . [Full Text PDF of this Article]
