In addition to conventional bypass surgery, endovascular treatment of popliteal artery aneurysms has recently been increasingly reported. However, there are few reports of peripheral stent grafts for the treatment of pseudoaneurysms after femoropopliteal bypass, as in the present case. An 82-year-old man underwent right superficial femoral-left popliteal artery bypass and right common iliac-external iliac artery stenting for arteriosclerosis obliterans 7 years ago. He visited our outpatient clinic for popliteal pain persisting for one month. Enhanced CT revealed a pseudoaneurysm of the distal anastomosis site. Peripheral stentgraft, VIABAHN (W. L. Gore, Flagstaff, AZ, USA), was urgently implanted to cover the distal anastomosis. And the patient was discharged 5 days after surgery with no perioperative complications.
