The inferior epigastric artery was used as a free graft for direct myocardial revascularization in 22 patients from October 1987 to July 1988. The artery was used either alone or along with internal mammary artery or saphenous vein grafts. The inferior epigastric artery was dissected through an infraumbilical incision without entrance into the peritoneal(More)
From January 1980 to December 1988, 44 patients with chronic aortic dissection and aortic insufficiency underwent operation. This group of patients was analyzed to evaluate the outcome of those in whom the aortic valve was preserved compared with those having valve replacement. The overall preoperative characteristics of the two groups were similar except(More)
CABG was performed in a patient with severe angina pectoris who had previous successful renal transplantation. Renal function, blood biochemistry and lymphocytes T and B did not show significant changes in the postoperative period. No postoperative complications were observed.

Twenty-four mongrel dogs, weighing 13 to 24 kg, were used to study the effectiveness of anastomosis by Argon Laser beam. After anesthesia, intubation and controlled ventilation, they were submitted to three types of vascular anastomoses: saphenous vein intercarotid artery bypass; left mammary artery/left anterior descending coronary artery bypass; and(More)
The cases of 3 patients with an aneurysm of the innominate artery treated surgically are reported. The clinical manifestations were different, and the surgical procedures employed also varied. In 1 patient, the neck of the aneurysm was isolated and clamped near the aortic arch. It was closed, and a graft was interposed between the ascending aorta and the(More)
Heart valve replacement has initiated special research efforts and has led to debate among surgeons from different surgical services. It is in this area of cardiac surgery that complications are frequent. This paper is a summarized review of the problems related to valve replacement by the Starr-Edwards prosthesis at the University of Sao Paulo Medical(More)
