Saphenous vein preparation for coronary artery bypass grafting using a cardioplegia delivery set.

Many techniques of saphenous vein preparation for coronary artery bypass grafting and their relation to endothelial preservation and graft patency have been published. We describe a method for final preparation of saphenous vein segments that uses the patient's undiluted heparinized blood infused at physiologic arterial pressure with a standard cardioplegia delivery apparatus. This method provides excellent demonstration of vein caliber and allows for quick identification and control of any previously undetected side branches or leaks. No additional equipment or instruments are required, and preparation can be performed before or after the institution of cardiopulmonary bypass.
