Objective: Complete myocardial revascularization is the gold standard in the treatment of multivessel coronary artery disease (CAD). However, the success of this procedure is limited by low patency of venous grafts. Left internal mammary artery (LIMA) is the conduit with best patency and best clinical results. For this reason in the last years the use of arterial conduits as radial artery is increased. The aim of this study is to value patency of radial artery by-pass graft used in composite conduits at mid term follow up. Methods: 50 patients who underwent from January to March 2008 to surgical off pump revascularization with composite arterial conduits were studied with 64-slices Multidetector Computed Tomography (MDCT). Mean number of grafts was 2.5; Index of Completeness of Revascularization (ICOR) was 0.95%. We studied 104 conduits ( 49 LIMA; 52 R.A.; 3 RIMA), 50 composite grafts ( 4 K graft; 42 Y graft; 2 π graft; 2 I conduit ),94 distal anastomosis, 40 Safenous Vein Grafts (SVG).

For this reason in the last years the use of arterial conduits as radial artery is increased. The aim of this study is to value patency of radial artery by-pass graft used in composite conduits at mid term follow up.
