It was reported during procedure to perform acute blood circulation recanalization therapy for m2 obstruction, a microcatheter and a retriever was guided using guidewire.It was reported that the patient¿s anatomy was very tortuous which caused difficulty in advancing the devices to the target site.Stent retriever was able to cross the obstruction site and was deployed.Accompanying microcatheter was removed and subject distal access catheter was placed along the retriever wire.Physician confirmed bleeding from the lesion site via imaging immediately after induction, integration with the stent retriever and removal from the body.A balloon catheter was expanded and waited for several minutes under blood collection blockage, but hemostasis was not obtained.The physician then guided another microcatheter and vascular embolization was performed using 3 coils and nbca (n-butyl cyanoacrylate).After the procedure patient was noted to have paralysis and aphasia.Preoperative condition of the patient is unknown and it is unable to confirm whether the symptom have worsened.No further information was provided.
