The physician was using the surefire precision infusion system to deliver y90 radioembolization spheres to a tumor in the liver.Prior to infusion of the radioembolization spheres, the physician coiled the right gastric artery to prevent flow of embolics to the stomach.The surefire precision was placed distal to the coiled vessel.During infusion no slow flow or reflux of the radioembolization spheres was observed.Following the radioembolization procedure a pet ct image showed radiation activity in the antrum of the stomach.Patient was admitted to the hospital and discharged after 5 days.Endoscopy showed 2 small ulcers in the stomach.No other medical or surgical interventions were reported.Based upon discussion with the physician, user error in device positioning and appropriate device selection for the vessel size may have contributed to the event.Based upon no observation of slow flow or reflux during the procedure, the event is potentially due to a secondary unidentified vessel leading to stomach, but no images of the procedure were provided to confirm.
