CABG stands for which medical procedure?

• A. Cardiac Artery Bypass Graft
• B. Cerebral Artery Bypass Graft
• C. Coronary Aorta Bypass Graft
• D. Coronary Artery Bypass Graft

Answer: (D)

Understanding what this abbreviation stands for and what the procedure does is key. CABG means Coronary Artery Bypass Graft. It’s a heart surgery used when coronary arteries are narrowed or blocked and heart muscle isn’t getting enough blood. A graft vessel is connected to create a new route for blood to flow around the blocked segment, typically from the aorta to a point beyond the blockage in the coronary artery. Grafts usually come from the internal thoracic artery, a saphenous vein, or the radial artery. This restores blood supply to the heart muscle and helps relieve angina and reduce heart attack risk. Other options point to arteries in the brain or change the target to the aorta, which isn’t how this heart procedure is described.
