External stenting of saphenous vein bypass grafts does not affect intraoperative transit time flow measurement
Saphenous vein grafts (SVG) are the most commonly used conduits for coronary artery bypass operations (CABG) despite their sub optimal long term patency. External stenting of SVG (eSVS(r) mesh) was recently proposed to improve their long term patency. Transit time flow measurement (TTFM) is a well described method for intraoperative quality control for CABG.
