Multidetector computed tomography imaging of aortoenteric fistula.

Three case reports illustrating multidetector computed tomography (CT) imaging findings of secondary aortoenteric fistula (AEF) are described and presented in axial sections, multiplanar reformats, and 3-dimensional reconstruction. Fistulae occurred in the early and late postgrafting period and involved both end-to-end and end-to-side aortic graft anastomoses. Multidetector CT is quick and accurate in the diagnosis of bleeding AEF.
