The pipeline device will not be returned for evaluation as it was implanted in the patient.Based on the reported information, there did not appear to have been any defect of the device during implantation.The event occurred in the patient post-procedure and its cause is not known.Tsai, y., <(>&<)> wong, h.(2016, june).Spontaneous migration of the pipeline embolization device: case report and review of the literature [abstract].Interventional neuroradiology, 22(1s), 21.Doi: 10.1177/1591019916648040.

Medtronic received information from literature that a pipeline migrated after implantation.The patient underwent pipeline embolization device implantation and coil embolization of an unruptured, giant aneurysm in the distal internal carotid artery (ica).It was reported that at the three-month follow-up ct angiogram, distal migration of the pipeline was noted.The patient underwent placement of a second pipeline for coverage of the aneurysm.In the one-year follow-up angiogram, complete obliteration of the aneurysm was noted.
