conduit anastomosis
Surgical connection between a bypass graft conduit and target coronary artery or aorta.
Full Definition
Conduit anastomosis refers to the surgical connection created between a bypass graft conduit (such as internal mammary artery, saphenous vein, or radial artery) and either a coronary artery (distal anastomosis) or the aorta (proximal anastomosis). The quality and patency of these anastomoses are critical determinants of long-term graft function and patient outcomes. Technical factors affecting anastomotic success include vessel size match, surgical technique, conduit handling, and the absence of tension or kinking. Intraoperative assessment may include transit-time flow measurement and graft angiography to evaluate anastomotic integrity and ensure adequate graft flow.
