Use of the eSVS Mesh: External Vein Support Does Not Negatively Impact Early Graft Patency

Abstract

The aim of this study was to assess early graft patency in eSVS Mesh-covered saphenous vein grafts (SVGs) in patients undergoing coronary artery bypass grafting. In 20 patients meeting criteria for double arterial grafting to the left-sided coronary system and eSVS Mesh-covered SVG to the right-sided coronary system, patency was evaluated intraoperatively by transit time flow measurement and at 5 days postoperatively by computed tomographic angiography. Twenty patients underwent 49 arterial and 22 venous grafts (mean, 3.55/patient) using off-pump techniques. All grafts were determined to be patent intraoperatively. On computed tomographic angiography, arterial graft patency was 100%. In one venous anastomosis, the distal limb of a sequential graft was occluded, for an overall patency rate of 95%. The eSVS Mesh does not compromise early SVG patency.
