RESUMO
Coronary artery bypass grafting (CABG) without cardiopulmonary bypass (off-pump CABG) was performed on a patient with a brain tumor. A patient with effort angina of the left anterior descending artery (LAD), and diagonal branch stenosis was referred to us for CABG. He had a mass lesion in the brain that was diagnosed as meningioma involving the internal carotid artery and a middle cerebral artery. To avoid brain complications, we performed off-pump CABG using the internal thoracic and radial arteries to the LAD and a diagonal branch. Off-pump CABG was an effective method to avoid brain complications for patients with a brain tumor involving cerebral vessels.

BACKGROUND: Multiple arterial revascularization is feasible because of the excellent long-term patency of the arterial grafts compared with venous grafts. We present a new operative technique for multiple arterial revascularization using composite radial and internal thoracic arterial grafts. METHODS: Between January and September 1997, 12 patients had coronary artery bypass grafting with inverted T graft. The indications for inverted T graft were aortic calcification in 4 patients, repeat coronary artery bypass grafting in 1 patient, and total arterial revascularization in 7 young patients. The inverted T graft was constructed by interconnecting the coronary arteries and radial artery with end-to-side and side-to-side anastomoses, and by anastomosing the internal thoracic artery to the side of radial artery. RESULTS: Overall, 38 distal anastomoses (average number per patient, 3.2) were made with an inverted T graft. There were no deaths or perioperative myocardial infarctions. Postoperative angiography disclosed that all of the anastomoses were patent. CONCLUSION: This technique allows multiple arterial revascularizations without technical difficulty. It is useful in patients with aortic calcification, repeat coronary artery bypass grafting patients, and young patients who are candidates for total arterial revascularization.
