[The second coronary reoperation via the left thoracotomy without cardiopulmonary bypass].

A 75-year-old female who had underwent coronary artery bypass grafting (CABG) reoperation 2 years before was readmitted because of unstable angina. Two arterial grafts and one saphenous vein graft (SVG) were all occluded one and half year after the primary operation. The second operation was approached via the repeated sternotomy. LAD and RCA were revascularized with a Y-shaped SVG which had only one inflow. Coronary angiogram revealed stenosis of LMT and RCA and occlusion of the inflow of the Y-shaped SVG. We performed the 3rd CABG via the left thoracotomy without cardiopulmonary bypass for revascularization of the LAD area. A new SVG was anastomosed from the descending aorta to the old SVG just proximal to the anastomotic site with LAD. Local coronary occlusion time was 7 min without any hemodynamic or electrocardiographic deteriorations. The operation was successfully performed in 3 hr 55 min. The patient recovered well uneventfully. Postoperative angiogram showed that the new SVG was adequately patent and she was discharged without angina. We conclude that CABG without cardiopulmonary bypass via the left thoracotomy is an useful alternative to decrease mortality and morbidity for reoperative myocardial reveascularization.
