[Evaluation of bypass patency in the radial artery with intermediate term observation].

After an initial learning experience in the early 70's, radial artery is now used as the second arterial graft of choice (after both ITAs). The aim of the study was to compare patency rates of venous and arterial grafts--especially radial artery--in mid-term follow up period. 19 patients with stable angina and 11 with unstable angina underwent coronary artery bypass grafting with CPB. The type of conduits used for grafting were the same in all patients. All patients underwent catheterization control. 28 LIMA grafts and 27 radial artery grafts were patent 31 months after CABG. Vein grafts were found patent in 80%.
