The Radial Artery: Current Concepts on Its Use in Coronary Artery Revascularization

The radial artery (RA) can be used as part of an arterial revascularization strategy in coronary artery bypass grafting (CABG). It is easy to harvest. and several randomized controlled trials and meta-analyses have reported superior long-term patency over saphenous vein grafts. However, the RA is not used as frequently as the saphenous vein and questions remain regarding its optimum use as a conduit. This article comprehensively appraises current evidence surrounding outcomes, patient selection, harvesting technique, intraoperative strategy, and graft spasm prophylaxis to provide a contemporary review of the use of the RA as a conduit in CABG.
