Angiographic results after the use of a sutureless aortic connector for proximal vein graft anastomoses

Early and midterm patency of the proximal anastomoses of saphenous vein grafts made with a Symmetry Aortic Connector System

“…Concerning early graft patency, Donsky and colleagues 12 reported thrombotic occlusions of ACS sites, and there have been several reports of early occlusion with ACS associated with graft kinking or inadequate graft angle. 7,8 In this study, results showed acceptable early graft patency. We selected target vessels that seemed to possess enough runoff to distinguish the cause of early occlusion as being from the aortic device rather than from poor runoff.…”

Análise dos resultados imediatos de estudo comparativo entre anastomose mecânica aortosafena versus convencional

“…Antona et al [11] have found a 94.7% patency in the catheterism performed in the postoperative period. In a study by Mack et al [12], comprising 36 patients, it was observed a patency of 86.6%; Wiklund et al [13] have found a permeability of 90% supported by angiography. Endo et al [7], in a group of 15 patients, have found on the postoperative angiography all the anastomoses patent and only in two was found 30% of stenoses.…”

Assessment of Coronary Artery Bypass Graft (CABG) Patency and Graft Disease Using Multidetector Computed Tomography (MDCT)

“…The device, called the Symmetry Bypass System aortic connector (St Jude Medical, St Paul, Minn), alters the common appearance of the bypass graft by requiring the aortic connector to be anastomosed perpendicularly to the aorta (Mack et al, 2003;Poston et al, 2004). Recent reports have documented the development of significant stenosis and occlusion in 13.7%-15.5% of vein grafts attached with the aortic connector (Carrel et al, 2003;Wiklund et al, 2002). In order to support the course of the aortovenous anastomosis, the left-sided SVG is connected to the left side of the aorta, stabilizing the graft on top of the main pulmonary artery.…”
