It was reported that procedure was to treat a lesion in a heavily calcified, 80% stenosed, right superficial femoral artery.
A 6 x 60 mm armada 35 percutaneous transluminal angioplasty (pta) catheter was advanced to the lesion without resistance.
The balloon was inflated to 10 atmospheres, but on the second inflation the balloon ruptured before reaching nominal pressure.
During removal of the pta catheter from the anatomy, the balloon caught on the edge of the unspecified 6f short introducer sheath and a portion of the balloon separated from the shaft.
The pta catheter was removed from the anatomy.
The 6f short introducer sheath was removed from the anatomy and replaced with a longer introducer sheath in an unsuccessful attempt to capture the balloon fragment.
A cut down procedure was performed to remove the balloon fragment from the anatomy.
The procedure was completed with the successful deployment of an unspecified stent implant.
No additional information provided.
