Medtronic received information that the patient developed a cerebral infarction a few days after medtronic liquid embolic embolization treatment.Prior to the event, the medtronic liquid embolic was injected from the distal end of the left pica.It was reported that there was difficulty removing the microcatheter because the tip was stuck.Once the catheter was removed, there was separation and movement of an medtronic liquid embolic lump.The patient was undergoing embolization treatment of an arteriovenous malformation (avm).The medtronic liquid embolic embolization was performed in the left pica, but the postoperative mri confirmed cerebral infarction in the pc area.This event occurred during the treatment of an arteriovenous malformation (avm), the feeder was severely tortuous.Onyx was injected at 0.25 / 90 seconds.It was reported that there was onyx reflux to the catheter, there was some resistance, but it was not hard to remove the catheter.Removal of nidus was performed.There was no vasospasm.Some left visual field disorder remained.The condition was not very good since bleeding occurred originally.The patient was planned to be transferred to a rehabilitation facility later.
