Question

In Coronary Artery Bypass Grafting (CABG), in order to bypass the blocked region of the coronary artery surgeon uses?

• A. Only arteries from another part of body
• B. Only veins from another part of body
• C. Artery or a vein from another part of body
• D. Only artificial arteries made from porous plastic fibres of dacron or teflon

Answer 1

Answer: (C)

Artery or a vein from another part of body

During CABG, a healthy artery or vein from the body is connected, or grafted, to the blocked coronary artery. The grafted artery or vein bypasses (that is, goes around) the blocked portion of the coronary artery. This creates a new passage, and oxygen-rich blood is routed around the blockage to the heart muscle.

So, the correct answer is (C)
