Radial artery conduits for coronary artery bypass grafting: current perspective.

250 The Journal of Thoracic and Cardio T otal arterial revascularization offers the potential to avoid the problems associated with vein graft failure. Bilateral internal thoracic arteries (ITAs) are the conduits of first choice because of excellent shortand long-term patency and the possibility of improved survival. The radial artery (RA) is easily harvested, versatile, has excellent handling characteristics, and has become the arterial conduit of third choice. Issues remain concerning its optimal use, however, particularly with reference to preoperative assessment, harvesting techniques, vasospasm prophylaxis, grafting strategy, and long-term patency. This article critically examines the current evidence for these important aspects of RA use.
