We present a case of true aneurysm of the brachial artery which is an extremely rare type of peripheral aneurysm. A 74-year-old man was admitted to our hospital because of a large brachial mass. He had a history of chronic renal failure due to diabetic nephropathy and had received hemodialysis for 10 years. He had an operation of surfaced brachial artery 4 years earlier. After this operation, the surgical wound became infected, and the surfaced brachial artery could not be used for hemodialysis. Digital subtraction angiography revealed a large aneurysm of the left brachial artery. Therefore, we treated the brachial arterial aneurysm with a saphenous vein graft. Although we had believed the aneurysm to be a pseudoaneurysm because of the history of wound infection after a previous operation, it was diagnosed as a true aneurysm on the basis of the pathological findings.
