arterial conduit
Patient's own artery used as a bypass graft in coronary artery surgery, typically offering superior long-term patency.
Full Definition
An arterial conduit is a native artery harvested from the patient and used to create a bypass around blocked coronary arteries. Common arterial conduits include the left internal mammary artery (LIMA), right internal mammary artery (RIMA), radial artery, and gastroepiploic artery. These grafts generally provide better long-term patency rates compared to venous grafts due to their resistance to atherosclerosis and superior endothelial function.
Usage
Usage note: Specify the source artery when editing surgical reports.
