How is coronary artery bypass graft performed?

Carefully. The distal end of the internal mammary artery is anastomosed to the coronary artery distal to the atheromatous plaque using 8-0 polypropilene and high power magnification. Radial artery or grater saphenous vein grafts are anastomosed to the ascending aorta and tho the coronary distal to the plaque. Obviously the thorax has to be entered and cardiopulmonary bypass may or not be used, .
By surgery. When an artery is blocked, the flow of blood is impeded and blood flow distal to the blockage is through meager collateral arteries. The tissues that are dependent on that blood flow become ischemic or wanting blood/oxygen. Blood flow has to be restored by using another blood vessel, e.g., mammary/radial artery or saphenous vein, to divert/bypass the blocked artery under cardiopulmonary bypass.
