It was reported the procedure was to treat a mildly calcified 70% stenosed, de novo lesion in the superficial femoral artery.The armada 18 balloon dilatation catheter (bdc) was inserted through a 4f introducer sheath and percutaneous transluminal angioplasty was performed in the left leg.The armada 18 balloon was removed; however the bdc could not be reinserted through the introducer sheath.To treat the right leg, another antegrade puncture was performed and a 6f introducer sheath was used.The armada bdc was reinserted through the 6f introducer sheath however during the first inflation, the balloon ruptured at nominal pressure (8 atmospheres).The armada bdc was removed and the procedure was completed with an unspecified bdc.There were no adverse patient effects and no clinically significant delay in the procedure.No additional information was provided.
