Selection of saphenous vein bypass gradt diameter to support patency of the stenosed coronary artery.
Injudicious selection of a saphenous vein graft can adversely affect the the late postoperative patency of the proximal coronary artery which it bypasses. The purpose of this investigation was to deduce an upper bound for graft diameter, at small angle of distal anastomosis, below which the stenosed artery will remain patent, from a mathematical model of aortocoronary bypass haemodynamics.
