Radial Artery Patency After transradial Access: effective and easy way to reducethe radial artery occlusion rate, results of the CRASOC(Compression Of Radial Arteries Without Occlusion) Study


From January 2009 to June 2011, we randomized 2107 TRA to low (13cc of air) versus ultra low (10 cc) inflation volume in the TR Band™ compression device. If bleeding occurred, 2 cc were added. After device positioning, type of compression was assessed (“patent hemostasis” or not). Compression was maintained for at least 4 hours. Radial artery patency was evaluated at 24 h by pulse oximetry during ulnar compression. Factors related to patency defined as positive pulse oximetry (PPO) were analyzed.
