On 5 … The following was received via email:</br>On 5/4/20, Piedmont Athens Regional Medical Center (GA 4-1) experienced a misadministration of BTG's TheraSphere Y-90 product. The plan of treatment was for (the treating physician) to deliver 120 Gy to the patient's left hepatic lobe with 1.62 GBq (43.78 milliCuries) of Y-90. The treating physician positioned the microcatheter in the left hepatic artery and verified positioning with a left hepatic arteriogram. With the microcatheter in this position, the treating physician began administering the microspheres. However, only a portion of the dose was delivered as the catheter quickly became occluded. Because of the patient's tortuous hepatic vasculature, the assessment is that a kink in the microcatheter prevented the majority of the dose from being delivered.</br>The delivered activity was calculated by comparing pre- and post-treatment survey meter measurements of the administration equipment as outlined in TheraSphere's administration procedure. The delivered activity to the patient was 0.28 GBq (7.52 milliCuries). The delivered activity is approximately 83 percent less than the prescribed activity. Post treatment surveys of all gowns, syringes, gloves, drapes, floor coverings, and trash revealed no contamination of the surgical suite. Post treatment planar imaging revealed no extrahepatic deposition of activity. The treating physician explained our inability to deliver the full dose with the patient and a plan was made for the patient to return on 6/5/20 for a second attempt at treating the left hepatic lobe.</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. +
