The following was received from the State … The following was received from the State of Minnesota via email:</br>Please note the medical event reported today to the Minnesota Department of Health Radioactive Materials Unit by Mayo Clinic in Rochester, MN.</br>The licensee reports that on April 29, 2015, a male patient was treated with Y-90 TheraSpheres. The written directive prescribed 62.1 mCi of Y-90 (120 Gy dose). The administration proceeded as expected with the assistance of interventional radiology and nuclear medicine. As part of the procedure, the licensee uses a survey meter to survey the Y-90 microsphere vial to determine that microspheres have been administered to the patient. The procedure was described as 'uneventful' and following the initial flushing the dose rate from the vial/tubing had not decreased to zero. The physician continued with three additional flushes as part of the normal procedure. The vial/tubing dose rate did not reduce to zero.</br>The waste material was collected and counted according the manufacturer's instructions. The licensee determined approximately 33% of the Y-90 activity was not delivered to the patient. Administered activity was estimated to be 41.85 mCi (84 Gy). Physicians anticipate no negative impact to the patient since the 'tumoricidal' dose, according to the manufacturer, is 80-150 Gy,</br>The patient has been notified. The referring physician was out of town on the day of the event and the licensee notified his fellow.</br>The licensee is continuing with an investigation. </br>The Minnesota Department of Health considers this investigation open and will provide more information will be as it becomes available.</br>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.necessarily result in harm to the patient. +
