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® 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.
The aim of this study is to assess whether external stenting of SVG affects perioperative TTFM.
Mesh covered SVG (n = 13)
Bare SVG (n = 13)
Simultaneous concomitant operation
CBP time (min)
Cross Clamp Time (min)
There was no significant difference between two groups regarding pre and peri-operative parameters, although more patients in the eSVS® mesh group had concomitant procedures (3, 23% vs. 2, 15%, P > 0.99). All SVG were patent in both groups at the end of the surgical procedure and TTFM values were similar. eSVS® mesh group had a trend for longer cardiopulmonary and aortic cross clamping times, which didn't reach statistical significance.
External stenting of SVG by eSVS® mesh does not extend the operative times. All SVG showed excellent flow and eSVS® mesh coverage didn't impede TTFM or provide graft flow different to controls.
