“…Miana compared RA and RITA as a second graft, demonstrating similar immediate results, but with a longer operative time in the RITA group [ 14 ] . In our previous studies, there was no time measurement for RA harvesting, but it was always harvested simultaneously with the sternum opening; it was always ready before the LITA harvesting was finished, thus wasting no time.…”

Introduction Left internal thoracic artery to left anterior descending artery (LITA-LADA) grafting has become a fundamental part of coronary artery bypass grafting (CABG). This grafting has led to an increased use of other arterial conduits, of which the radial artery (RA) is the most popular. Whether RA can have the same long-term patency as LITA is controversial. The objective of this study is to access the long-term clinical follow-up and, when available, the patency rate of RA grafts. Methods Twenty-six patients from a previous study with critical stenosis in all target vessels underwent complete arterial CABG with LITA and RA grafts from 1996 to 2003. They all underwent midterm multidetector computed tomography after surgery with the association of at least one patent LITA and one patent RA graft. Results Twelve patients (46%) are alive with no angina symptoms. Six patients underwent a second image exam 12 to 16 years (average of 14 years) after surgery, with a total of six LITA-LADA and 14 RA grafts with 100% patency rate. Clinical follow-up five to 23 years after surgery (average of 14 years) showed only one death 12 years after surgery related to coronary artery disease (CAD) (3,8%). Another 12 patients died of non-CAD. Conclusion Patients with midterm associated LITA and RA patent grafts show similar optimal long-term patency rates of both types of grafts with excellent clinical outcome.

“…Miana et al [21] presented a study utilizing the RITA (20 patients) or the radial artery (38 patients) as the second arterial graft. The authors did not observe statistical differences in the immediate evolution of the patients when death, reoperation for bleeding and mediastinitis were assessed.…”

Dupla artéria torácica esqueletizada versus convencional na revascularização do miocárdio sem CEC em diabéticosDouble skeletonized internal thoracic artery vs. double conventional internal thoracic artery in diabetic patients submitted to OPCAB Abstract Objective: To evaluate the influence of the technique used in the dissection of thoracic arteries in the evolution of diabetic patients submitted to OPCAB.Methods: Seventy diabetic patients submitted to OPCAB using bilateral thoracic arteries were evaluated. In Group A, thoracic arteries were dissected as a pedicle, while in Group B they were skeletonized.Results: The mean age of patients in Group A was 52.14 ± 7.35 years old versus 55.71 ± 8.1 years for Group B (p=0.057). In Group A, six patients (17.1%) were insulin dependent against nine (25.7%) in Group B (p = 0.561). The EUROSCORE was 3.97 ± 2.49 for Group A opposed to 4.14 ± 3.06 for Group B (p = 0.879). The number of distal anastomoses in Group A was 3 ± 0.77 versus 3.03 ± 0.89 in Group B (p = 0.981). Three patients (8.57%) from Group A presented with mediastinitis. Insulin dependence was the only significant risk factor (p=0.008) for mediastinitis. In this group the use of skeletonized ITAs significantly decreased the incidence of mediastinitis (p = 0.044).Conclusion: The incidence of mediastinitis was lower in the group for which thoracic arteries were dissected using skeletonization. Among insulin-dependent diabetics, 50% of the patients from the group in which the pedicled internal thoracic artery was utilized presented with mediastinitis; the utilization of skeletonized ITAs significantly decreases the incidence of mediastinitis.

“…Meireles et al5 compared the effectiveness of diamond-like carbon coated stainless steel stent versus uncoated stent implantation in patients with coronary artery disease, but conclude that no better outcomes resulted from the use of the coated stent. Miana et al6 discuss immediate results of right internal thoracic artery and radial artery as the second arterial graft in myocardial revascularization and find that 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. Viaro et al7, examined endothelial dysfunction caused by acute pressure distension of human Saphenous Vein used for myocardial revascularization and find that although vascular reactivity impairment was not demonstrated in vitro, the CD34 expression, measured by imunohistochemistry, shows there is endothelium dysfunction at pressures of 300 mmHg.…”
