CABG anatomy
Post-surgical coronary anatomy including bypass grafts, native vessels, and anastomotic sites.
Full Definition
CABG anatomy encompasses the complex post-surgical coronary circulation including arterial and venous bypass grafts, native coronary vessels, and anastomotic connections. Understanding CABG anatomy is essential for angiographic interpretation, as bypass grafts create alternative perfusion pathways that may compete with native vessel flow. Arterial grafts (LIMA, RIMA, radial artery) typically demonstrate different flow characteristics compared to saphenous vein grafts and have superior long-term patency. Angiographic evaluation requires systematic assessment of all grafts, native vessels, and anastomotic sites to identify stenosis, occlusion, or competitive flow. The complexity increases with multiple grafts and sequential anastomoses.
Usage
Usage note: Document all grafts systematically and note competitive flow when present.
