Medtronic received information that during treatment, the pipeline flex (ped) device migrated proximal after placement.The patient was undergoing flow diversion of a small unruptured saccular aneurysm located in left internal carotid artery, measuring 7mmx5mm, landing zone distal 3mm, proximal 4mm.The vessel was observed as severely tortuous.It was reported that ped was delivered without incident.The proximal end was lazy open; however, it opened once fully deployed.A non-medtronic guidewire was used to smooth expand the ped at the proximal end.The ped looked fully opened and apposed.When the distal end was released, the device was alleged to have migrated proximally.The ped is now partially crossing the neck but not fully covering the neck of the aneurysm.Multiple times were made to cross the ped with the idea to delivery another ped distal to the first.However, the wire was unable to navigate distally.The patient will be retreated.The patient was reported to be asymptomatic and no other complications were reported.The patient was dual antiplatelet treatment.The pru level was 130.
