Medtronic received a report of pipeline flex incomplete opening during a procedure.Information that pipeline flex device flattened and stretched during the procedure.The pipeline did not open.Fistula happened during advancement of the navien and phenom 027 in an attempt to open the flattened area.The patient was undergoing embolization treatment for an unruptured amorphous aneurysm located in right internal carotid artery (ica) landing zone distal 3.2mm proximal 4.7mm.The vessel was observed moderately tortuous.It was reported that pipeline was prepped per ifu, no issues during deployment.Pipeline did appear to be stretching before detachment and was detached over a bend which resulted in flattening of the device.The physician advanced a guide catheter and microcatheter to open the flattened area.A run with contrast revealed a fistula that the physician believes was catheter induced.The physician decided to ¿sack¿ the vessel as the right ica on imaging was being well fed from contralateral flow.Right ica was sacrificed; the patient¿s contralateral flow was feeding right circulation.There were no patient symptoms or complications associated with this event.
