On September 6, 2012, the [Pennsylvania Department of Environmental Protection, Bureau of Radiation Protection (PADEPBRP)] Central Office received notification via a phone call about this medical event.
The patient received an administration of approximately 1.4 millicuries (mCi) of Y-90 microspheres to the wrong treatment site. The intended treatment was to administer approximately 24 mCi to the left lobe of the liver through three different arteries. During the administration of one of the split doses, the Interventional Radiologist (IR) incorrectly positioned the catheter in the right hepatic artery. A portion of the one split dose was administered to the right lobe of the liver before the IR realized that the catheter was not in the correct artery.
Cause of the event: Human Error.
Actions: Both the referring physician and the patient have been notified of the medical event. The [PADEPBRP] plans to do a reactive inspection.
