“…A similar controversy exists about the best place for the proximal anastomosis of the radial artery. Although most studies did not find clinical or angiographic differences between the two techniques [41][42][43], Italian researchers suggested that there is a better behavior of the graft anastomosed to the aorta when the degree of coronary artery obstruction is between 70 and 90% [43].…”

Resultados imediatos da artéria torácica interna direita e artéria radial como segundo enxerto arterial em revascularização do miocárdioImmediate results of right internal thoracic artery and radial artery as the second arterial graft in myocardial revascularization Abstract Objective: We sought to compare early clinical outcomes in patients receiving a right internal thoracic artery or a radial artery as the second arterial graft in myocardial revascularization.Methods: We retrospectively studied 58 consecutive patients who underwent coronary artery bypass surgery and received both a left internal thoracic artery graft and either a right internal thoracic artery (n=20) or a radial artery graft (n=38), between January 2004 and March 2006. Hospital mortality, pleural drainage, operative time and postoperative complications were analyzed.Results: There were no significant preoperative differences between groups. There was only one (1.7%) in-hospital death which occurred in the Radial Group. Operative times was significantly higher in the Right Internal Thoracic Group (p-value = 0.0018), but were not associated with increased Intensive Care Unit stays, mechanical ventilation or other postoperative complications. We were able to perform significantly more distal anastomosis using the radial artery than the right internal thoracic artery (1.57 versus 1.05: pvalue =0.003).Conclusion: In our group of patients, the use of a right internal thoracic artery as a second arterial graft was associated with a prolonged operative time, but had no interference with the immediate clinical outcomes. 61MIANA, LA ET AL -Immediate results of right internal thoracic artery and radial artery as the second arterial graft in myocardial revascularization Braz J Cardiovasc Surg 2007; 22(1): 60-67

“…The incidence of perioperative myocardial infarction in CABG ranges from 2 to 15% [ 16 ] , and this variation can be explained by the absence of a gold standard test in the specific situation of infarction after coronary revascularization. In addition, electrocardiographic changes and elevation of cardiac enzymes in the postoperative period, even in patients without myocardial ischemia may occur [ 17 , 18 ] .…”

Introduction The most common method used for myocardial protection is administering cardioplegic solution in the coronary circulation. Nevertheless, protection may be achieved by intermittent perfusion of the coronary system with patient's own blood. The intermittent perfusion may be performed by multiple sequences of clamping and opening of the aortic clamp or due single clamping and accessory cannulation of the aortic root as in the improved technique proposed in this study, reperfusion without the need for multiple clamping of the aorta. Objective To evaluate the clinical outcome and the occurrence of neurological events in in-hospital patients submitted to myocardial revascularization surgery with the "improved technique" of intermittent perfusion of the aortic root with single clamping. Methods This is a prospective, cross-sectional, observational study that describes a myocardial management technique that consists of intermittent perfusion of the aortic root with single clamping in which 50 patients (mean age 58.5±7.19 years old) have been submitted to the myocardial revasculrization surgery under the proposed technique. Clinical and laboratory variables, pre- and post-surgery, have been assessed. Results The mean peak level of post-surgery CKMB was 51.64±27.10 U/L in the second post-surgery and of troponin I was 3.35±4.39 ng/ml in the fourth post-surgery, within normal limits. No deaths have occurred and one patient presented mild neurological disorder. Hemodynamic monitoring has not indicated any changes. Conclusion The myocardial revascularization surgery by perfusion with the improved technique with intermittent aortic root with single clamping proved to be safe, enabling satisfactory clinical results.

“…For these peculiarities, several comparative studies have been presented in the international literature identifying the radial artery as an anatomic site susceptible to atherosclerotic and pre-atherosclerotic lesions [13][14][15][16], especially in the elderly [17].…”
