The physician was attempting to use an evercross pta balloon during an upper extremity fistulogram.The physician first dilated the balloon to nominal pressure with lack of resolution of the stenosis.It was reported the balloon was then dilated to less than burst-pressure and the balloon ruptured in the midline in a transverse manner (not along the long axis of the balloon).There were 2 free ends of the balloon still located on the treatment wire.The balloon could not be removed through the sheath.A snare catheter was advanced to the end of the most central end of the balloon, while keeping on the wire, and the entire system, including the sheath, was withdrawn over the wire.The procedure then proceeded, and the patient was treated without rupture of the vessel.No further patient injury was reported.
