A 71-year-old man underwent a medical checkup at another hospital with principal complaint of chest discomfort, and was diagnosed by computed tomography（CT）to have a left subclavian artery aneurysm. The CT revealed a 33-mm saccular aneurysm that was located at the proximal portion of the left subclavian artery. Because of the high risk of surgery, we planned to insert a stent graft into the left subclavian artery. We could not avoid occluding the ostium of the left vertebral artery with commercially-available stent grafts, and so decided to insert a surgeon-modified stent graft, in which the fabric of the distal portion of the stent graft was stripped away. The surgeon-modified stent graft was inserted from the conduit of the left axillary artery. Postoperative course was uneventful and the postoperative examination confirmed complete exclusion of the aneurysm and patency of the left vertebral artery.
