We experienced six cases of pseudoaneurysm of the peripheral artery which occurred after stab wound or after diagnostic and operative procedures. Among 6 cases, 4 cases of pseudoaneurysm were developed in the femoral arteries, and others were the subclavian and the axillary artery. Two of 6 cases were combined with previous arterio enous fistula. Doppler imaging and angiogram were performed for the dignosis and an operation. Operative procedures were resection of the aneurysm, ligation of the involved arteries and reconstruction of the artery with the autogenous saphenous vein or the cephalic vein graft. Each operations were successfully performed without any disability.
