      There is evidence that the use of Y-grafts attached to the left internal mammary artery – to – left anterior descending artery graft may compromise the patency of the distal limb of the left internal mammary artery. We describe a technique (split radial technique) that avoids the use of Y-grafts by constructing two aorto-coronary grafts from a single radial artery. The split radial technique requires the harvesting of the radial artery in its entirety from the brachial bifurcation to the radial styloid. The first radial artery distal anastomosis is performed and the required length of conduit is determined. The conduit is transected, leaving a sufficiently long radial segment for a second aorto-coronary graft. A clinical follow-up 41 weeks after surgery of the first 37 patients in whom the split radial technique was used showed no deaths or major complications. This suggests that the split radial technique is a useful and safe way to maximise the use of radial artery conduit and to avoid the potential risk of compromising internal mammary artery patency with Y-grafts.
