Two patients who underwent "redo" aortic graft replacement in which the original thrombosed graft was oversewn but not removed subsequently devel oped graft-enteric erosions that involved the oversewn graft. Each patient un derwent successful removal of all intraabdominal graft material, oversewing of the aortic stump and extraanatomical bypass. These cases emphasize the need to remove any defunctionalized graft material and to cover all new and retained graft with soft tissue at the time of aortic graft reoperation if graft-enteric ero sion is to be avoided.
