BACKGROUND: A 61-year-old man with a previous endovascular repair and stage 5 chronic kidney disease presented with a symptomatic 4.5-cm left internal iliac artery aneurysm. The decision was made to proceed with endovascular repair. METHODS: The preoperative magnetic resonance angiography (MRA) scan was linked to on-table rotational imaging using the Artis zeego Fusion program (Siemens AG, Forchheim, Germany). Using the fused image as a road map, we undertook coil embolization of the left internal iliac artery, and a tapered stent graft was extended from the previous graft into the external iliac artery. RESULTS: Completion angiography revealed exclusion of the aneurysm sac. Three milliliters of contrast were used throughout the procedure. A follow-up magnetic resonance angiography scan at 1 month and duplex ultrasonography at 1 year revealed continued exclusion of the aneurysm sac. The patient's renal function remained unchanged. CONCLUSIONS: This case shows that in a patient with severe chronic kidney disease, fusion of preoperative imaging with intraoperative rotational imaging is feasible and can limit significantly the amount of contrast used during a complex endovascular procedure.
