It was reported that during a procedure of the moderately tortuous, radial/brachial artery, the balance middleweight guide wire was advanced and positioned in the armpit artery without difficulty.Additional attempts to move/position the guide wire met resistance and were unsuccessful but not due to the anatomy.Under fluoroscopy a distal 30 cm guide wire separation was confirmed.The fragment was removed surgically.There was no reported clinically significant delay in the procedure.No additional information was provided.
