[Redo coronary artery bypass grafting after pneumonectomy]

A 77-year-old man who had undergone left pneumonectomy 16 years and quadruple coronary artery bypass grafting (CABG) 4 years previously presented with unstable angina pectoris. Coronary angiography revealed severe stenosis of the left main trunk and the proximal left anterior descending artery(LAD), and the severely narrowed left internal thoracic artery (LITA)-LAD graft. Computed tomography(CT) presented a marked shift of the heart and great vessels into the left hemithorax with a hyperinflated right lung crossing the midline. The LAD would not seem to be accessible by median sternotomy. Off-pump coronary artery bypass grafting (OPCAB) with a saphenous vein graft to LAD was performed through a rib-cross left thoracotomy. The patient's postoperative course was uneventful, and postoperative CT revealed a patent graft. OPCAB through rib-cross thoracotomy is safe and useful and can be an option for redo CABG, particularly in instances of previous pneumonectomy.
