It was reported, a patient was undergoing a planned procedure to dilate a severely calcified common iliac artery which had been stented some years before, implant date and stent manufacturer unknown.Another manufacturer's introducer caught on the stent and an effort was made to re-modulate the stent using advance pta 5 balloon catheters, which perforated.These were easily removed from the patient's anatomy.Subsequently, a stent-in-stent procedure was performed while post-dilating the stent with an advance 35 lp low profile balloon catheter.The balloon catheter ruptured circumferentially during the first inflation at 7 atmospheres just prior to reaching nominal pressure.Another manufacturer's inflation device was used for the inflation.Ultravist contrast and normal saline were used in a 1 to 1 ratio.While trying to remove the ruptured advance 35 lp low profile balloon catheter through another manufacturer's introducer the balloon tore at the top.An attempt was made to retrieve the torn piece through a second 8 french (fr) introducer using a snare device but this was not successful.The procedure was aborted at this point and the patient required surgery to completely remove the retained piece of the balloon.The surgery was successful and the patient was fine.The original procedure was rescheduled for another date.No further adverse effects have been reported.
