It was reported that the procedure was to treat a lesion in the right tibial perineal artery with calcification and tortuosity.The 4x48mm xience skypoint stent was advanced to the target lesion and the stent was implanted; however, the stent balloon fail to deflate.Therefore, an unspecified guide wire (gw) was used to puncture the balloon to remove the delivery system, ending the procedure.The stent was noted to be fully opposed to the vessel was and successfully implanted.There was no adverse patient sequela and no clinically significant delay reported in the procedure.No additional information was provided.
