Abstract:
A 65-year-old patient underwent double coronary artery bypass grafting using the left internal thoracic artery on the left anterior descending coronary artery and nitinol alloy mesh [external Saphenous Vein Support (eSVS)]-covered saphenous vein graft to the right posterior descending coronary artery. Transit-time flow measurements (TTFMs) were obtained on meshed and bare parts of the vein graft. There was no difference in TTFM parameters (flow, pulsatility index, and diastolic fraction values) obtained from the eSVS mesh-covered and the uncovered parts of the venous graft. This observation confirms that eSVS mesh does not interfere with TTFM on venous coronary bypass conduits.
