RESUMO
In the years 1994 and 1995, 1087 patients underwent coronary artery bypass grafting at our institution. Of these, 297 were operated on without cardiopulmonary bypass. 239 were male, and 58 were female. Their ages ranged from 28 to 81 years (54.43 +/- 9.63). Of the total, 294 were operated on electively, two as a coronary reoperations, and one as an emergency after a failed percutaneous transluminal coronary angioplasty procedure. In all patients complete revascularization was the aim, and a cardiopulmonary bypass team was kept on standby. Median sternotomy was performed as the exposure in all patients, except a patient who underwent a coronary reoperation through a left thoracotomy incision. The average of the distal anastomoses was 1.51 +/- 0.6, ranging from 1 to 3. The left internal thoracic artery was used in 292 operations, which was an individual graft in 284, a sequential graft in five, and a free graft in four. Major complications in the early postoperative period were noted in three patients as reoperation for excessive bleeding. One patient had reoperation for left internal thoracic artery spasm, and one patient had lower extremity ischemia caused by intraoartic balloon counterpulsation. Hospital mortality was 0.3% with one patient. It is our belief that in selected cases coronary artery bypass grafting without cardiopulmonary bypass is a safe procedure with the advantage of improvement in recovery during the postoperative period.

Coronary bypass surgery in a patient with functioning renal graft is reported. Surgery was carried out using standard operative techniques providing some precautions for renal graft protection: i.e. adequate mean perfusion pressure, volume replacement, and renal outflow during cardiopulmonary bypass, and appropriate prophylactic antibiotic and immunosuppressive therapy. Postoperative course was uneventful and blood urea nitrogen and serum creatinine levels were comparable to the preoperative levels. Three months after operation the patient was found to be asymptomatic.
