autologous conduit
A patient's own vessel used as graft material for bypass surgery. Editorial note: preferred over 'autogenous' in formal medical writing.
Full Definition
Autologous conduit refers to vascular graft material harvested from the patient's own body, most commonly the saphenous vein or internal mammary artery. This terminology is critical in vascular surgery documentation as it distinguishes from synthetic (prosthetic) grafts and allografts. Editors should note that 'autologous' is the preferred medical term over the colloquial 'autogenous,' and the term 'conduit' specifically refers to the vessel's function as a bypass channel rather than its anatomical origin.
Usage
Usage note: Always use 'autologous' rather than 'autogenous' in formal medical documentation.
