Event or Problem Description
It was reported the physician selected a gore® viatorr® tips endoprosthesis with controlled expansion for a transjugular intrahepatic portosystemic shunt procedure.The stent was successfully placed; however, when the stent was approximately 80% deployed, the deployment line broke and the end of the covered portion of the stent remained constrained.Additional manipulation of the introducer sheath and delivery system freed the remaining portion of deployment line and the stent fully deployed.The small piece of deployment line that was still attached to the stent remained in the patient, most likely constrained between the liver and stent.The patient was doing well following the procedure.
