[Infection and digestive bleeding: late complications of aortofemoral bypass surgery]

Graft-enteric fistulas and (the most uncommon) graft-enteric erosions are feared complications of aortic reconstructive surgery and infection and hemorrhage are their major clinical manifestations. A case considered unusual due to the simultaneous presence of two graft-enteric erosions: duodenal and sigmoid is reported. The first erosion was revealed by endoscopy performed for gastrointestinal bleeding. The role played by infection and mechanical factors in the pathogenesis of these complications is then discussed.
