Aorto-enteric Fistula Secondary to the Cannibalization of an Aortic Graft

The incidence of graft-enteric fistulae following aortic aneurysm repair ranges from 0.4 to 2.4% with duodenal involvement in 75% of cases and carries a mortality rate approaching 55%. Graft-enteric erosion is an even rarer complication of aortic surgery. We report a case of graft-enteric erosion following trouser graft for aorto-iliac occlusive disease that involved complete cannibalization of the limb of the graft into the ileal lumen.
