We sometimes encounter the case that we have to make an anastomosis between a prosthetic graft and an autologous vein graft in revascularization of a lower extremity. However, it is said that the intimal hyperplasia in the anastomosis site of a prosthetic graft and autologous vein graft has a tendency to become severe in the long term postoperatively. We herein report a case in which a vein cuff（St. Mary’s boot）technique was very useful to prevent recurrent stenosis due to intimal hyperplasia. No recurrence of stenosis in repair lesion has been detected for 7.5 years after operation.
