TI  - The Risk Factor Analysis for the Late Graft Failure of Radial Artery Graft in
      Coronary Artery Bypass Grafting.

AB  - OBJECTIVE: The aim of this retrospective study was to investigate the early
      operative results and detect the factors influencing the fate of radial artery
      grafts (RAGs) by evaluating the mid-term patency. METHODS: We retrospectively
      reviewed 410 patients who underwent isolated coronary artery bypass grafting
      using RAG. RAGs were anastomosed to 526 coronary arteries. Mid-term angiography
      was performed in 214 patients at an average 4.9 years after the operation.
      RESULTS: The early patency of RAGs was 97.6%. Cumulative 5-year patency was 86.5%
      for RAG, 94.1% for LITA graft, and 81.0% for saphenous vein graft (SVG). RAG was 
      significantly superior to SVG in mid-term patency. Individual grafting (not
      sequential grafting) (hazard ratio [HR]: 2.535; 95% confidence interval [CI]:
      1.293-5.281; p = 0.006) and grafting to the target coronary artery with </=75%
      proximal stenosis (HR: 1.947; 95% CI: 1.090-3.484; p = 0.025) were found to be
      independent risk factors influencing late RAG patency. CONCLUSIONS: The patency
      of RAGs was superior to that of SVGs in the studied population. When using RAGs, 
      grafting to the target vessel with severe proximal stenosis is favorable. The RAG
      is suitable for sequential grafting.
