saphenous vein graft
Pronunciation: sah-FEE-nuss
A conduit harvested from the patient's leg and used to bypass blocked coronary arteries, commonly requiring intervention due to accelerated atherosclerosis.
Full Definition
Saphenous vein grafts (SVGs) are conduits created using the patient's great saphenous vein to bypass occluded coronary arteries during cardiac surgery. These grafts are prone to accelerated atherosclerosis and often require percutaneous intervention within 5-10 years of implantation. SVG interventions present unique challenges including higher embolic risk, no-reflow phenomenon, and the need for embolic protection devices. The clinical approach to SVG disease differs significantly from native vessel intervention.
Usage
Usage note: Often abbreviated as SVG; avoid confusing with saphenous artery which is not commonly used for grafting.
