The licensee notified the Department on June 7, 2021 at 1300 [EDT] that it had determined at 1200 [EDT] a medical event had occurred because of a Y-90 Therasphere procedure that occurred on June 4, 2021. The licensee is reporting that the administered dose differed from the prescribed dose by more that 20 percent. The written directive specified that the patient was to be administered with 135.5 mCi of Y-90 Therasphere to the left lobe of the liver. During the procedure it was discovered that there was an apparent leak in the microcatheter. The dose delivered calculated to be less than 93 mCi. The remainder of the dose had leaked onto the floor. The licensee has decontaminated the room. The On-call Duty Officer is meeting with the licensee's Radiation Safety Officer on June 8, 2021 to investigate this incident. This is an initial notification and further updates will be forthcoming once the investigation is complete.
