- Análise da medida de fluxo por tempo de trânsito da artéria torácica interna direita anastomosada para a artéria interventricular anterior comparada com a artéria torácica interna esquerda Rodrigo Milani Daniela de Moraes Aline Sanches Rodrigo Jardim Thais Lumikoski Gabriela Miotto Vitor Hugo Santana Paulo Roberto Brofman Medicina off Pump Mammary Arteries Internal Mammary Coronary Artery Bypass Introduction: We evaluated with transit time flow the perfor - mance of the right and left thoracic arteries when used as a graft for the left anterior descending artery. Methods: Fifty patients undergoing surgery for myocardial revascularization without cardiopulmonary bypass were divided into two groups. In group A patients received graft of right inter - nal mammary artery to the anterior interventricular branch. In group B patients received graft of left internal mammary artery to the same branch. At the end of the operation the flow was assessed by measuring transit time. Results: In group A, mean age was 60.6±9.49 years. The average height and weight of the group was 80.4±10.32 kg and 169.2±6.86 cm. The average number of grafts per patient in this group was 3.28±1.49. The mean flow and distal resistance obtained in right internal thoracic artery was 42.1±23.4 ml/min and 2.8±0.9 respectively. In group B, the mean age was 59.8±9.7 years. The average height and weight of this group was 77.7±14.22 kg and 166.0±8.2 cm. The average number of grafts per patient in this group was 3.08 ±0.82. The mean flow and distal resistance observed in this group was 34.2±19.1 ml/min and 2.0±0.7. There were no deaths in this series. Conclusion: Right internal mammary artery presented a similar behavior to left internal mammary artery when anasto - mosed to the anterior interventricular branch of the left coronary artery. There was no statistical difference between the measured flow obtained between both arteries. 2014 artículo científico 0102-7638 https://www.redalyc.org/articulo.oa?id=398941893007 pt http://www.redalyc.org/revista.oa?id=3989 Revista Brasileira de Cirurgia Cardiovascular/Brazilian Journal of Cardiovascular Surgery application/pdf Sociedade Brasileira de Cirurgia Cardiovascular Revista Brasileira de Cirurgia Cardiovascular/Brazilian Journal of Cardiovascular Surgery (Brasil) Num.2 Vol.29
