Event Description
|
It was reported that the stent partially deployed and fractured.Vascular access was obtained via contralateral approach.The greater than 90% stenosed target lesion was located in the moderately tortuous and severely calcified superficial femoral artery (sfa).A 6x120x130 eluvia drug-eluting vascular stent system was selected for use.A filter was placed below the lesion with high resistance prior to balloon dilatation and stent deployment.The lesion was pre-dilated.During deployment after use of the thumbwheel, the pull grip was extended to its max length and broke.About a quarter of the stent was deployed into the patient when the mechanism failed.The stent was pulled into the sheath; however the stent broke.The quarter of the stent that was deployed was left inside the patient and covered with a separate stent.The other part of the undeployed stent was successfully pulled out of the patient.The procedure was completed as planned and the patients status is fine.There were no patient complications.
