title: [Experiences of reoperative coronary artery bypass grafting by left thoracotomy without aortic clamping].
abstract: We reported two cases which had reoperative coronary artery bypass grafting (CABG) through the left thoracotomy approach without aortic clamping with good results. Case 1. A 50-year-old man, who underwent a double CABG to left anterior descending coronary artery (LAD) and right coronary artery (RCA) in 1983, had a recurrent unstable angina due to new significant stenosis of the diagonal branch (DG) and obtuse marginal branch (OM) in 1989. He was reoperated upon, having a new double CABG to DG and OM through the left thoracotomy using hypothermic ventricular fibrillation without aortic clamping for the myocardial protection without any blood transfusion. Case 2. A 61-year-old man, who underwent a double CABG to LAD and RCA in 1982, had a recurrent unstable angina and a left ventricular aneurysm in 1991. He had a reoperation of a single CABG to OM combined with left ventricular aneurysmectomy by the same approach. Both cases showed satisfactory recoveries of the left ventricular function in the early postoperative period and patent grafts on postoperative angiograms. The left thoracotomy approach is a preferable alternative to median resternotomy for the reoperative CABG to OM, DG and left ventricular aneurysmectomy.
