Percutaneous transluminal angioplasty of radial artery grafts

The radial artery is being used with increasing frequency to replace the saphenous vein as a coronary artery bypass graft, in the belief that it will provide improved long-term patency. Several centers have confirmed that the early results of surgery using the radial artery seem to be better than those obtained with saphenous grafts. Despite these apparent gains, early failure of the radial artery graft can occur and is frequently associated with symptomatic myocardial ischemia. Percutaneous angioplasty is an alternative to reoperation to treat lesions occurring on radial artery grafts. We report on 4 patients who underwent angioplasty of radial artery grafts.
