Minimally invasive direct coronary artery bypass grafting using the saphenous vein in redo CABG.
We describe a patient who underwent minimally invasive direct coronary artery bypass (MIDCAB), who had previously undergone coronary artery bypass grafting (CABG) through a median sternotomy with a left internal mammary artery (LIMA) graft to the left anterior descending artery (LAD) and a right gastroepiploic artery (GEA) graft to the posterior descending artery. MIDCAB was less invasive and was an effective alternative procedure for the second operation. Because the patient had no LIMA or GEA available for a graft because of prior use, we used a saphenous vein graft (SVG) for bypassing from the left subclavian artery to the coronary artery by MIDCAB via a left minithoracotomy. The left subclavian artery was selected as the proximal anastomotic site because this artery was less diseased and was easier to reach. The SVG-to-coronary artery anastomosis was facilitated by firm adhesion between the epicardium and the pericardium, which reduced the motion of the epicardium itself. These results suggest that the procedure is safe and promising in selected cases of redo CABG.
