These areas are identified prior to surgery by cardiac catheterization. The vein is measured to provide enough length to reach the ascending aorta, both when the heart is contracting and expanding. The vein is cut to the appropriate length. Additional bypass grafts are performed as needed by the same procedure. In most patients, more than one coronary artery develops blockages.
Surgeons frequently perform several bypass grafts in a single operation.
