POTENTIAL MEDICAL EVENT
The following information was provided by the licensee via phone and email:
"In accordance with 10 CFR 35.3045, [Henry Ford Hospital is] reporting a potential medical event.
"On May 8, 2023, a patient was treated with Y-90 TheraSpheres. The total activity prescribed in the written directive was 11.5 mCi to the left lobe of the liver and 11.37 mCi was delivered (99.2 percent). The therapeutic dose was prescribed to be delivered to segment 4 of the left lobe of the liver. During treatment, the position of the catheter was verified and was determined by the physician to be in the correct position. However, post-treatment bremsstrahlung imaging reviewed today on 5/9/2023 indicated some activity was shunted unexpectedly to segments 2 and 3 of the left lobe of the liver. Based on preliminary calculations, this discrepancy could be categorized as a medical event."

The following information was provided by the licensee via phone:
Since the exposure was due to shunting, the licensee determined that this event is not reportable in accordance with the licensing guide. This event is being retracted.
Notified R3DO (Feliz-Adorno), NMSS (Rivera-Capella), and NMSS Events Notification.
A Medical Event may indicate potential problems in a medical facility's use of radioactive materials. It does not necessarily result in harm to the patient.

After the procedure, it was determined that the patient received doses differed from the prescribed doses by more than 20 percent. The patient was prescribed doses of 14.5 mCi and 21.7 mCi. The patient received 5.3 mCi (for the syringe dose of 14.2 mCi) and 12.31 mCi (for the syringe dose of 21.5 mCi). Delivered doses differed by 37.3 percent and 57.2 percent respectively.

EMERGENCY EXHAUST INOPERABLE
The following information was provided by the licensee via phone and email:
"At 1127 CDT on 5/16/2023, during the reperformance of test procedure 'STS PE-006, Charcoal Adsorber In-Place Leak Test' due to a failure from the previous day, both trains of emergency exhaust were rendered inoperable due to incorrect performance of the procedure. Performers incorrectly de-energized the humidity control heating coil for the unit not under test, rendering it inoperable. This issue was identified and rectified at 1138 CDT on 5/16/2023, exiting the LCO [limiting condition of operation] for both trains inoperable at that time. There was no impact to the health and safety of the public."
