Event Description

Medtronic received information regarding a mirage guidewire that had difficulty navigating the marathon catheter to the intended location and catheter occlusion that occurred in the same case.The patient was undergoing a procedure for glue treatment of a dural arteriovenous fistula via middle meningeal artery access.Vessel tortuosity was severe.Access vessel diameter was 1.65mm.It was reported that the devices were prepared as indicated in the instructions for use.First, it was attempted to navigate the marathon catheter to the treatment location along a mirage guidewire.However, the marathon was not able to navigate on the mirage.The mirage guidewire was removed and replaced with a hybrid 010 wire which was used successfully with the marathon catheter.The catheter reached the target site and was flushed first with saline, followed by 5% dextrose.The glue injection was started but the glue did not come out the distal end of the catheter; there was resistance and the catheter was clogged.There were no associated patient symptoms and no injury.Additional information was received that the case was abandoned.The mirage wire lost its shape due to artery tortuosity, no damage was seen on the marathon per doctor.Additional information was received that the case was planned after few days with all competition materials in black up.It was performed with magic catheter and glue.The outcome was good.There was no patient harm due to case abandoned as it was an elective case.Additional information was received that the case was abandoned as the artery went in spasm and the fistula site was not seen.Even nimodipine didn't help.And hence it was planned dsa later and sos embolization.
