The following information was received from the
Colorado Department of Health via email:
On January 21, 2025, at 1400 MST, an authorized medical physicist for Community Hospital, reported a medical event to the Radiation Program of the Colorado Department of Public Health and Environment resulting from a yttrium-90 (Y-90) SIR-Sphere administration. The licensee reported that 78.8 percent (14.9 mCi) of the prescribed 18.9 mCi Y-90 dose was delivered to the treatment site and the remaining approximately 21.2 percent (4.4 mCi) of the prescribed dose remained in the delivery line post-procedure.
The licensee reported and confirmed that there was no shunting or other blockage and the patient did not experience any emergent medical conditions during the treatment that would have resulted in the medical event. At the conclusion of the case, the authorized user was delivering the dose as normal and did not encounter increased pressure or stasis. The licensee confirmed through post treatment radiation area surveys that no spills had occurred and that there was no additional significant radioactive material that was not accounted for. The Colorado Radiation program is continuing to investigate this medical event.
