Continuous Perfusion of Saphenous Vein by Oxygenated Blood during Beating Coronary Surgery

The saphenous vein remains the most commonly used conduit for coronary artery bypass surgery (CABG). However, the long-term success of surgical revascularization is largely limited by development of occlusion in vein grafts.. We sought to reduce graft ischemia by maintaining the blood flow into the harvested vein throughout surgery at lowest costs and without special devices..Patients and This study was conducted on three hundred patients aged 58.5 ± 8 years undergoing elective first-time off-pump CABG with saphenous veins.. In addition to preserving nutritional materials and oxygen, the veins harvested via this novel technique did not go into spasm and were not subjected to high-pressure distension, eventually resulting in minimal damage to the endothelium.. This technique confers favorable myocardial function and protection in the presence of left ventricular dysfunction, especially in elderly patients..
