It was reported that the procedure was to treat an 100% stenosed lesion in left superficial femoral artery (sfa) and popliteal artery.For post dilatation a 5x200mm armada 18 balloon dilatation catheter (bdc) was used; however, the balloon ruptured after 3 inflations at 8 atmospheres.Therefore, the bdc was removed from the patient without issue.Another same size armada 18 bdc was then used to continue post dilation; however, during the first inflation the second armada balloon was noted to have a leak of contrast at the base of the inflation port.During removal, the second bdc became stuck with the stent that had been implanted and could not be removed from the patient.Therefore, cut-down surgery was performed to remove the bdc.There was no adverse patient sequela.No additional information was provided.
