A 90-year-old man was referred to our hospital for lower abdominal pain and ecchymotic discoloration around the anus. A laboratory test revealed severe anemia（hemoglobin level, 5.7g/dl), and computed tomography（CT）showed a ruptured left internal iliac artery aneurysm（diameter, 60×44mm). Consequently, emergency endovascular stent-grafting treatment was performed. Under local anesthesia, the stent-graft was successfully inserted in the left common and external iliac arteries, covering the ostia of the internal iliac artery. A follow-up CT scan showed complete thrombosis of the left internal iliac artery aneurysm and no evidence of an endoleak. After the procedure, the patient was treated with hemodialysis for acute-on-chronic renal failure and was discharged after 2 months.
