Contrast-enhanced CT revealed a 23 mm pseudoaneurysm in the right RA and a solitary 23 mm aneurysm in the left internal iliac artery (Fig. 1).
Intraoperative digital angiography of the right renal artery.. Aortogram before the stent graft replacement shows the slightly enhanced origin of the right renal artery and blood pool to the right of aorta (arrow) (A). The right renal artery was excluded, and the pseudoaneurysm was no longer observed after the stent graft replacement (B).
