Sepsis and bleeding can lead to life-threatening complications, such as stent-graft infection and pseudoaneurysm, after stent-graft implantation. An 83 year-old woman was admitted to our hospital for sepsis 14 months after treatment with a balloon-expandable stent-graft for an arterio-ureteral fistula (AUF) between the right external iliac artery and the right ureter. Blood cultures were positive for methicillin-resistant Staphylococcus aureus and Candida tropicalis. A giant infectious pseudoaneurysm (44 × 70 mm) at the distal edge of the stent-graft was suspected of having caused the sepsis. Although endovascular therapy (EVT) was planned to correct the pseudoaneurysm, the right iliac artery spontaneously became occluded from the ostium of the right common iliac artery to the common femoral artery 5 days after diagnosing the pseudoaneurysm; hence, EVT was not performed. Antibiotic administration was continued, and blood culture results were negative. Although EVT using a stent graft for AUFs is effective, data on the chronic phase outcomes are limited. Therefore, patients with AUFs treated using stent-grafts should be carefully followed up.
