Coronary artery bypass grafts: conduits and illustrated destinations
THE CONTEXT
Coronary artery bypass graft surgery bypasses narrowed or stenosed coronary arteries using saphenous vein grafts or the internal mammary artery. The passage describes an example reconstructed using multidetector CT.
Bypass conduits
•
Narrowed or stenosed arteries can be bypassed using saphenous vein grafts connected to the aorta or by utilising the internal mammary artery.
Grafts shown in the CT example
•
The three-dimensional CT reconstruction shows patent saphenous vein grafts (SVG) to the right coronary artery (RCA), obtuse marginal branch (OM) and diagonal branch (LADD).
•
It also shows a left internal mammary artery graft (LIMA) to the left anterior descending (LAD) coronary artery.
