Transradial artery catheterization has become an accepted alternative approach to performing diagnostic and interventional coronary procedures. However, its usefulness can be limited by access site failure. We report on 12 patients in whom there was failure to cannulate the radial artery. Angiograms of the hand were performed on all patients through the ulnar sheath to determine the possible mechanism of failure to cannulate the radial artery and to determine the source of the blood supply to the hand. Irrespective of the mechanism of failure, each of the 12 procedures was subsequently successfully completed using the ipsilateral ulnar artery approach.
