[Two cases of coronary artery bypass grafting following radical mastectomy using bilateral internal thoracic arterial grafts].

We report two cases of coronary artery bypass grafting following radical mastectomy using bilateral internal thoracic arterial grafts. One was a 68-year-old woman with angina pectoris, and the other was a 71-year-old woman with old myocardial infarction. Dissection of the internal thoracic arterial pedicles from the chest wall was not so difficult in both cases. The pedicles had good patency and each free flow of them was enough. They had no postoperative complications. It may be a useful method to use the internal thoracic arterial grafts for a case of coronary artery bypass grafting after radical mastectomy.
