The following information was obtained from the
Illinois Emergency Management Agency (Agency) via email:
The licensee's radiation safety officer contacted the Agency to advise that a patient scheduled to receive Y-90 microsphere therapy (SirSpheres) for hepatocellular cancer on August 24, 2021, received only 77% of the dose prescribed in the written directive. This administration called for only 16.2 mCi of activity. The licensee's radiation safety officer is reviewing the delivery system as well as the specifics of the administration to determine root cause. The licensee suspects a clogged catheter but is currently investigating. No personnel or area contamination was reported. It is unclear at this point if the referring physician or the patient has been notified. An update has been requested within one hour and Agency staff noted the 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> notification requirement.
