The following information was obtained from the Commonwealth of
Pennsylvania via fax:
Event Description: The event involved a patient who was scheduled to be treated with 11.87 mCi of Y-90 microspheres (TheraSphere), but only received an estimated 5.07 mCi, or 43% of the prescribed dose. The licensee reported the event to the Department [Pennsylvania Department of Environmental Protection] on April 25, 2017. Initial indication is that there was a faulty connection on the catheter line that allowed a leak to occur. The patient and referring physician were notified the day of the procedure. No Jefferson personnel skin contamination occurred. However, gloves, drapes and the patient's skin were contaminated. The patient was quickly decontaminated with alcohol wipes. All remaining areas were also decontaminated. A skin calculation is currently being completed by the licensee to determine the patient's exposure, if any. No overexposure is believed to have occurred.
Cause of the Event: Unknown at this time. Suspected human error.
Actions: The Department will perform a reactive inspection. The licensee will update their procedure to include additional checks of the Y-90 administration kit. More information will be provided upon receipt.
