case_images: CT findings: (a) axial view of the fistula (arrow) between the AAA and the IVC:atheroma/thrombus surrounds the defect, (b) coronal view of the fistula (arrow) between the AAA and the IVC:atheroma/thrombus is seen around the defect, and (c) compression of the IVC (arrowhead) by the AAA.. CT: computed tomography; AAA: abdominal aortic aneurysm; IVC: inferior vena cava.

case_images: Enhanced CT showed an infrarenal AAA (92 x 75 mm2) and a short fistula (7 mm) running between the right lateral wall of the AAA and the inferior vena cava (IVC) (Figure 1(a) and (b)). The IVC was compressed by the aneurysm (Figure 1(c)).
case_images: Intraoperative photographs: (a) the fistula is 7.0 mm in diameter and atheroma/thrombus surrounds the defect (arrow) and (b) closure of the fistula with running 5-0 polypropylene sutures and a Dacron patch.

case_images: Then, we detected a fistula communicating with the IVC via a 7-mm defect in the right lateral wall of the aorta at 3 cm proximal to its bifurcation (Figure 2(a)), corresponding to the lesion detected preoperatively by CT. It was closed with running sutures of 5-0 polypropylene and a Dacron patch (Figure 2(b)).
