Foldback technique for aortic anastomosis of free right internal thoracic artery in coronary artery bypass grafting.
We herein report a new technique that we term "foldback plasty" for stenosis-free proximal anastomosis of free arterial grafts without using any other interposition materials. The arterial graft is first anastomosed to the aorta in side-to-side fashion, leaving 1 cm of remnant tissue at the proximal end. The reverse side of the graft is then opened longitudinally, starting at the proximal end, to just distal to the aortic anastomosis site. The new proximal graft flap is folded back and sutured onto the graft to close the longitudinal opening. The proximal anastomosis site is enlarged only by the graft tissue, and stenosis can be avoided even if the graft has a small caliber.
