REVASCULARIZACIÓN MIOCÁRDICA CON AMBAS ARTERIAS MAMARIAS INTERNAS, UN RETO PARA LOS CIRUJANOS CARDIOVASCULARES ACTUALES / Myocardial revascularization with both internal mammary arteries, a challenge for cardiovascular surgeons nowadays

Abstract

The left internal mammary artery is currently the most common graft in surgical myocardial revascularization. However, in spite of the works showing the effectiveness of the use of both mammary arteries, this technique remains a controversial topic in medical literature nowadays. Among the factors discouraging its use we have the good results of the myocardial revascularization with left internal mammary artery and with saphenous vein, a greater technicaldifficulty and a prolonged surgical time; as well as an increase in sternal complications. The advantages and disadvantages in the use of this procedure are discussed in this work, as well as the results presented by several authors. The surgical technique is also described.
