The procedure that requires the use of a healthy vein or artery to circumvent a coronary artery occlusion is **CABG** (Coronary Artery Bypass Grafting). In CABG, a graft is created using a healthy blood vessel taken from another part of the body (such as a vein from the leg or an artery from the chest) to bypass the blocked coronary arteries.
The other procedures listed:
- **Stent**: Involves placing a small mesh tube (stent) in a narrowed or blocked artery to keep it open, but does not involve bypassing the blockage with another vessel.
- **PTCA**: Stands for Percutaneous Transluminal Coronary Angioplasty, which is a procedure to widen narrowed or obstructed coronary arteries without using a graft.
- **Angioplasty**: Generally refers to the same process as PTCA, where a balloon is used to expand the artery, and does not involve bypassing with another vessel.
Therefore, the answer is **CABG**.
