saphenous vein graft
Pronunciation: sah-FEE-nus
Vein harvested from the leg used as a conduit for coronary artery bypass surgery.
Full Definition
Saphenous vein graft (SVG) refers to a segment of the saphenous vein harvested from the patient's leg and used as a bypass conduit to reroute blood around blocked coronary arteries. The great saphenous vein is the most commonly used conduit for coronary artery bypass grafting, though it has lower long-term patency rates compared to arterial conduits. Proper documentation includes the harvesting technique (open versus endoscopic), conduit quality, and anastomotic sites.
Usage
Usage note: Commonly abbreviated as SVG. Note correct spelling of 'saphenous' (not 'safenous').
