It was reported that the procedure was to treat the right common and superficial femoral arteries with calcification.During the procedure, the 7.0x80 mm armada 35 percutaneous transluminal angioplasty (pta) catheter was being used to post-dilate a stent.The balloon was inflated to 8 atmospheres and when it was attempted to increase the pressure, the balloon ruptured.Resistance was noted during removal with the sheath and it was tried to push the balloon and withdraw it together with the sheath.When pulled, a portion separated and the patient had to be sent to surgery to retrieve the separated portion of the balloon.The patient recovered well.No additional information was provided.
