CABG conduit
Vessels used as bypass grafts in coronary artery bypass surgery, including arterial and venous grafts.
Full Definition
CABG conduits are the vessels used to create bypass grafts during coronary artery bypass surgery. Common conduits include the left internal mammary artery (LIMA), right internal mammary artery (RIMA), radial artery, and saphenous vein grafts (SVG). In cardiovascular radiology reports, editors must distinguish between different conduit types as they have varying patency rates and clinical implications. Arterial conduits generally provide superior long-term outcomes compared to venous grafts.
Usage
Usage note: Always specify the type of conduit (arterial vs. venous). CABG should remain capitalized when used as an adjective.
