Btg medical assessment: the (b)(6) the pet images acquired after the treatment showed no concordance with the previous work up image (spect maa) as an important part of the activity was outside the liver.The system was set up correctly and the microcatheter was positioned in the left hepatic artery.The administration of the therapy was normal.It is unknown if the catheter moved during the therasphere administration leading to therasphere migration the possible cause could be due to vasospasm of the hepatic artery that led to a reflux of therasphere leading to therasphere migration.The patient is receiving prophylactic treatment with ondansetron and analgesia and is under observation and they are going to repeat the pet acquisition today.The site of the microsphere migration is not reported and they did not provide an estimation of the dose which went out of the liver.Conclusion: non-target disposition: severity - unknown; related to device; anticipated adverse event listed in the ifu/risk management documentation; seriousness - yes, prolongation of the hospitalisation and preventive measures to prevent deterioration of body structure/function.No batch review was possible for this case as the batch number has not been provided and the product was not returned for evaluation (device remains implanted in the patient).Additional information has been requested regarding the batch number; location of the extra hepatic deposition of therasphere; measurement of the dose deposition out of the liver; results of the next pet scan and any further prescribed treatment to the patient i.E.Antibiotics, proton pump inhibitor.No corrective/preventative action has been identified.Should we receive any information to enable further investigations, a follow-up report will be submitted.At this time this report is considered final.
