[Redo Coronary Artery Bypass Grafting Through Left Thoracotomy in Patient with Patent Left Internal Thoracic Artery Graft;Report of a Case].

A 61-year-old man was admitted because of unstable angina. The patient had a history of CABG [LITA-left anterior descending artery(LAD), aorta-saphenous vein graft(SVG)-posterolateral branch (PL)-diagonal branch (D1)]4 years ago. Coronary angiography revealed an occlusion of old SVG at proximal anastomosis site and a stenosis of native high lateral artery (HL). To reduce the risk of cardiac injury and damage to the patent grafts due at sternal reentry, we performed redo CABG through left thoracotomy. The proximal site of SVG was anastomosed to descending aorta using automated proximal anastomosis system. The SVG was anastomosed to the HL and old SVG in a sequential mode. Postoperative course was uneventful and the patient was discharged on postoperative day 14. Redo CABG through left thoracotomy provides safe and effective surgical approach in patient who requires revascularization of left circumflex territory.
