摘要
Coronary artery bypass without cardioplegia remains the preferred technique at many centers around the world. This report describes in detail a technique that emphasizes intermittent cross-clamping of the aorta at mild hypothermia (30-degrees-C). Since coronary bypass procedures require brief interruptions of coronary blood flow only for the distal anastomoses, the duration of myocardial ischemia with this technique is not prolonged by unexpected changes in the operative plan. Many bypass grafts can also be carried out without cross-clamping of the aorta by using local control of the coronary arteries. The increasing number of elderly patients with atherosclerotic aortas that cannot be safely clamped makes it helpful for all cardiac surgeons to be familiar with noncardioplegic techniques.
