• Types of grafts
  • Arterial graft
    • Internal thoracic artery (internal mammary artery)
      • Good accessibility, close proximity to the heart
      • Left thoracic artery is suitable for bridging stenoses in the left anterior descending artery due to their close spatial proximity.
    • Radial artery: performance modified Allen test before CABG
  • Venous graft (aortocoronary saphenous vein bypass, or ACVB)
    • Great saphenous vein (first choice in vein bypass grafts because of good surgical access to the long, superficial leg vein with suitable vessel cross-section)
