The following information was provided by the
Ohio Bureau of Radiation Protection via email:
A patient was scheduled to receive 30 mCi Y-90 to the right lobe of the liver in segments 5/6, but only 11.2 mCi was delivered. This is an underdose of 63 percent.
The authorized user (AU) and interventional radiologist physician verified catheter placement by contrast injection and fluoroscopy prior to the procedure and continued to monitor the catheter position during the treatment. During the procedure, the AU noted that saline was leaking from the top of the acrylic vial holder inside the delivery box and that there was insufficient pressure to mix/suspend the microspheres in the dose vial. It was also noted the catheter had moved from the original target. The AU determined the dose could not be delivered as prescribed and abandoned the procedure.
The patient and referring physician were notified.
Investigation is pending.
