[Reoperative coronary revascularization without cardiopulmonary bypass]

We report a case of successful reoperation of coronary revascularization without cardiopulmonary bypass. The patient was a 62-year-old man, who had undergone coronary artery bypass grafting (CABG) to the LAD and CX with two saphenous vein grafts (SVG) for the left main lesion 12 years before. He required reoperation for unstable angina due to progressive ischemic heart disease and the diseased SVG. Preoperative coronary angiogram revealed total occlusion of major 3 branches and the diseased SVG to the LAD. The reoperation was performed without cardiopulmonary bypass through the repeated median sternotomy for revascularization of the LAD and RCA. The left internal thoracic artery and the gastroepiploic artery were anastomosed to the LAD and RCA under the beating heart without any hemodynamic or electrocardiographic deteriorations. The operation was uneventfully finished in 3 hr 40 min. without the use of blood products. Postoperative angiogram showed both new grafts were widely patent, and he was discharged 14 days after the operation without angina. We also performed 4 other cases of reoperative CABG without cardiopulmonary bypass, and conclude that this technique is a safe and effective alternative in a carefully selected group of patients for reoperative CABG to reduce several technical problems related to coronary reoperation.
