Long-Term Patency of 1108 Radial Arterial-Coronary Angiograms Over 10 Years

To avoid late vein graft atheroma and failure, we have used arterial grafts extensively in coronary operations. The radial artery (RA) is the conduit of second choice. This study determined the long-term patency of the RA as a coronary graft.Two independent observers evaluated 1108 consecutive postoperative RA conduit angiograms performed between January 1997 and June 2007 for cardiac symptoms.
