The following information was received via email from the State of Illinois:
On June 11, the Radiation Safety Officer/Medical Physicist for Northwest Community Hospital in Arlington Heights, IL called to report a medical event. The previous morning a patient was to be administered approximately 38 milliCi of Y-90 labeled microspheres for treatment of liver cancer in the left lobe of the liver via the hepatic artery. Instead, approximately only 21 milliCi was delivered. Post treatment measurements of the delivery system showed substantially elevated readings at the catheter/vial interface suggesting either blockage or perhaps improper flow allowing the microspheres to coagulate. The physician is considering an increase in dosage for the patient's second treatment which is scheduled in two to three weeks in order that the ideal dose be delivered. However, if that cannot be accomplished, the interventional radiologist does not believe the patient's health to be adversely affected by the under dose. A written report of the event from the licensee is pending at this time.
IL Report Number: IL-14010
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.
