[Percutaneous intervention to a radial coronary artery graft.  Initial results and follow-up]. 
The use of radial artery grafts for coronary bypass surgery is becoming more frequent.  However, experience with percutaneous coronary intervention for radial artery graft failure is limited.  We describe a patient with a radial artery graft in whom angina reappeared because of de novo stenosis in the graft.  The patient was successfully treated with balloon angioplasty and stenting.  At 6 months he again had angina due to a second de novo stenosis of the radial artery graft, which was also treated with angioplasty.  At follow-up the patient remained asymptomatic with no evidence of ischemia.
