Fig. 3From: Patency of conduits in patients who received internal mammary artery, radial artery and saphenous vein graftsConduit patency and perfect patency (GLMM) n = 196 anastomoses. Arterial conduit patency was high, not different from each other despite differing coronary territory grafting and all but one was also perfectly patent. However, vein graft had lower patency and very low perfect patency with progressive decline over time expected.
