INTRODUCTION
The radial artery (RA) is often used for coronary angiography and percutaneous intervention. With the increased use of total arterial revascularization in accordance with recent guidelines, the RA is more commonly used in coronary artery bypass grafting (CABG).1 Studies have shown superior long-term patency rates of the RA compared to the saphenous vein.2Questions have been raised as to whether the RA should be used as an arterial graft after transradial (TR) catheterization as it may affect graft patency. Here we discuss two patients with prior TR interventions who after 8-17years, still show structural and histologic changes.
