The following was received from the Commonwealth of
Virginia (the Agency) via email:
On December 1, 2021 at 0525 EST, the Virginia Radioactive Materials Program (RMP) received a report from the licensee that a medical event involving Yttrium-90 microspheres occurred on 11/30/2021 (procedure date). According to the written directive, the prescribed dose to the right liver (treatment site) was 27.6 millicuries (mCi). The procedure was interrupted due to the artery spasm, which could not be identified before the treatment began and as a result, only 14.5 mCi of the prescribed dosage was delivered to the treatment site (right liver). The administered dosage was estimated to be 47% less than the prescribed dose. According to the licensee's preliminary report, no healthy tissue or organ other than the treatment site was exposed because of this event and the patient was notified. The RMP will schedule to investigate the event and this report will be updated when the final investigation report is available.
