Revascularização miocárdica com artéria radial: influência da anastomose proximal na oclusão a médio e longo prazo

Abstract

Revascularização miocárdica com artéria radial: influência da anastomose proximal na oclusão a médio e longo prazo Coronary artery bypass grafting using the radial artery: influence of proximal anastomosis site in mid-term and long-term graft patency Abstract Objective: To determine whether the proximal anastomosis interferes or not in mid-and long-term patency of these grafts.Methods: One hundred twenty-three out of 481 patients who had undergone surgery using radial artery (RA) were restudied. The mean age was 58. 39CARNEIRO, LJ ET AL -Coronary artery bypass grafting using the radial artery: influence of proximal anastomosis site in mid-term and long-term graft patency Bras Cir Cardiovasc 2009; 24(1): 38-43 Rev

Myocardial revascularization in the XXI century

“…Today we know that, given its feature of spasticity, its use should be avoided in coronary arteries with lesions smaller than 70%, due to the risk of flow competition, which could eventually lead to the occurrence of string sign (diffuse tapering throughout graft) [24]. The hypothesis that the proximal anastomosis could interfere with the graft flow has not been proven [25].…”
