Event Description
|
It was reported that stent deployment issues occurred, the stent elongated, the tip detached, and it was difficult to remove the delivery system.The target lesion was located in the totally occluded minimally calcified superficial femoral artery (sfa).The lesion was predilated and a contralateral approach was used to access the lesion.A 6x100 75 cm eluvia¿ drug-eluting vascular stent system was selected for the procedure.Upon stent deployment, the proximal part of the stent remained attached to the unspecified 45cm 6fr delivery sheath.When the delivery system was attempted to be removed, it became stuck.The delivery system was pulled very hard and the stent released.Due to the stent being trapped in the sheath when removal was performed, the stent elongated from 100mm to 200mm and became damaged.After removal, it was noticed that the tip of the delivery catheter was missing.The tip was located further down in the sfa.Another stent was deployed in the distal sfa to jail the tip of the delivery system.An additional stent was placed at the proximal end of the eluvia stent to keep it open due to the damage.The procedure was completed and the vessel was patent.No further complications were reported.The patient's condition was noted as stable.
