Question

Which vessel is most commonly used to bypass a damaged coronary artery in coronary bypass surgery?

O azygos vein
O internal carotid artery
O femoral artery
O great saphenous vein

Answer 1

The great saphenous vein is the most commonly used vessel for coronary bypass surgery to create a new path around a blocked coronary artery. Therefore, the correct option is D.

Step-by-step explanation:

The vessel most commonly used to bypass a damaged coronary artery in coronary bypass surgery is the great saphenous vein. This vein is preferred because it is long, easily accessible, and has the right diameter for bypassing the occluded areas in the coronary arteries. During the procedure, the great saphenous vein is harvested from the leg and used to create a new path around the blocked coronary artery, restoring blood flow to the heart muscle.
