    Abstract:
    Abstract Background: We describe our experience with the limited left thoracotomy strategy for reoperative coronary artery bypass graft (CABG)to the circumflex coronary artery system, emphasizing the indications, our particular operative technique, and early clinical follow-up. Methods: From January 2001 to January 2002, 8 consecutive patients underwent redo revascularization via limited left thoracotomy and without cardiopulmonary bypass. This operation was indicated for patients with recurrent myocardial ischemia confined to the lateral wall of the left ventricle, especially if a patent left internal thoracic artery (LITA)-to-left anterior descending coronary artery (LAD)graft was present. Results: All 8 patients underwent successful redo revascularization via limited left thoracotomy. Eight patients received 14 saphenous vein grafts (mean 1.7 grafts/patient). No instances of postoperative myocardial infarction or death occurred. During a follow-up period ranging from 1 to 12 months (mean, 5. 2 months), all patients were asymptomatic and without evidence of ischemia or infarction. Conclusions: For select patients who have patent LITA grafted into the LAD and who need redo CABG to the coronary artery circumflex system, the limited left thoracotomy approach without cardiopulmonary bypass is a safe operation and a less invasive alternative to repeat sternotomy and conventional CABG.
