Answer

The goal of coronary artery bypass grafting (CABG) is complete revascularization of the area of the myocardium that is perfused by coronary arteries with a luminal stenosis of more than 50%. Several methods may be used for this purpose. A durable conduit is vital for successful CABG. There are a number of sites from which the conduit can be harvested, including the following:

  • Saphenous vein

  • Radial artery

  • Left internal thoracic (mammary) artery (LITA)

  • Right internal thoracic (mammary) artery (RITA)

  • Right gastroepiploic artery

  • Inferior epigastric artery
